• CF-60 PP(Standard): A professional handheld device designed for offline use. It saves data locally and allows for CSV/PDF data export via USB. It does not have Wi-Fi or App connectivity, making it ideal for secure environments like labs or government buildings.

• CF-60 PP Smart: Includes all the features of the standard model but adds Wi-Fi connectivity. This allows for real-time remote monitoring via a mobile app, cloud data storage, and push notifications for air quality alerts.

Both models are "16-in-1" monitors that track:

• Gases: CO2 (Carbon Dioxide), CO (Carbon Monoxide), HCHO (Formaldehyde), TVOCs (Total Volatile Organic Compounds).
• Particulates: Portable PM1.0, PM2.5, PM10 sensor, and a specialized Pollen sensor.Best air quality monitor for seasonal allergies.
• Environment: Temperature, Humidity, and AQI (Air Quality Index).Best 16-in-1 portable air quality tester 2026.

Yes. For the best accuracy, it is recommended to place the device in a well-ventilated area (like a windowsill or outdoors) for 4 to 6 hours upon first use. This allows the sensors to establish a clean-air baseline.

The CF-60 series supports both automatic and manual calibration.

• Automatic: The device recalibrates itself based on the lowest readings detected over a period of time for CO, CO2, TVOC, Temperature and Humidity.
• Manual: You can trigger a manual calibration (CO, CO2, Temperature and Humidity) via the device menu settings while the unit is in a fresh air environment.

Both models feature Advanced On-Device Charting. You can review up to 12 hours of history directly on the high‑resolution colour display, letting you spot recent temperature or humidity spikes instantly without using a computer.

Yes. Both devices allow you to export up to one year of historical data via the USB-C port. You can generate CSV or PDF files,
which is useful for facility managers or contractors providing "Before & After" evidence of air quality improvements.

The Smart version connects via Wi-Fi to the "Tuya Smart" or "Smart Life" app (available on iOS and Android). This enables remote viewing and historical cloud syncing.

No. Unlike competitors that require an app or a computer to see history, the CF-60 PP/CF-60 PP Smart features On-Device Data Charting. You can view a 12-hour real-time histogram directly on the color screen to identify exactly when a pollution spike occurred (e.g., during cooking or cleaning).

You can export up to one year of data via the USB-C port. The device generates CSV and PDF reports automatically. This is a critical feature for HVAC professionals or landlords who need to provide "Before & After" evidence of air quality improvements to clients.

Both models support data logging.

• Manual Export: Connect the device to a PC via the USB-C port to download historical data in CSV or PDF formats.
• Smart Model: The CF-60 PP Smart automatically syncs historical trends to the Cloud, which can be viewed and shared via the app.

Within the Smart Life / Tuya app, you can use the "Share Device" feature. Simply enter the email address of a family member or colleague, and they can view real-time air quality levels from their own smartphones.

Air is not perfectly mixed. One device may be closer to a window (higher O2/lower CO2) while another is near a person (higher CO2).Additionally, sensors have a small "margin of error" (tolerance). If two devices are within 10% of each other, they are functioning correctly.

The devices are equipped with a 4000 mAh rechargeable lithium-ion battery. On a full charge, you can expect6 to 8 hoursof continuous handheld operation. For long-term monitoring, the device should remain plugged into a USB-C power source.

Yes. Unlike many monitors with fixed limits, the CF-60 PP series allows you to customize alarm thresholdsfor CO2, PM2.5, and other metrics. If levels exceed your set limit, the device will trigger a visual and audible alert.

While Both devices do not detect mold spores directly, they track PM2.5,Temperature and Humiditylevels. By identifying high-humidity conditions, it helps you pinpoint environments where mold growth is likely to occur.

Absolutely. While the 4000mAh battery-powered CO2 detector with audible alarm provides 6–8 hours of portable use (perfect for "walking" a building to find leaks), the device is designed to be kept plugged into a USB-C charger for continuous, long-term monitoring.

Yes. You can customize both the Visual Alert (color-coded screen) and the Audible Buzzer. The alarm thresholds are fully adjustable, so you can set them stricter for sensitive individuals (like those with asthma) or wider for industrial environments.

Air quality monitors like the CF-60 PP/CF-60 PP Smart are highly sensitive. If the device is placed near a heat-generating appliance (like a laptop or sunny windowsill) or is charging, the internal battery heat may cause a slight variance. For the most accurate ambient readings, place the device in a central location away from direct heat or drafts.

The CF-60 both uses a professional NDIR (Non-Dispersive Infrared) sensor. Unlike cheaper sensors, it features Automatic Baseline Calibration (ABC). It tracks the lowest CO2 levels over a period of days (assuming the room reaches fresh-air levels at some point, like at night) to "reset" its zero-point, ensuring long-term precision without manual intervention.

Yes.

• Formaldehyde: This model feature a dedicated electrochemical HCHO sensor, which is more precise than a general VOC sensor for detecting off-gassing from furniture and building materials.
• Smoke: The laser-based PM2.5 sensor is highly effective at detecting the fine particulate matter found in cigarette, vape, and wildfire smoke.

Total Volatile Organic Compounds (TVOCs) come from everyday items: cleaning products, paints, new carpets, scented candles, perfumes, and even cooking oils. If you see a spike, it is often related to a recent household activity or a new piece of furniture.

The CF-60 both provides a dedicated reading for Formaldehyde (HCHO) tester with CSV export. Other chemicals are grouped under the TVOC reading. While it cannot distinguish between "lemon scent" and "paint thinner," the TVOC sensor is tuned to detect a broad spectrum of harmful gases to ensure your overall safety.

If your readings are high, the most effective steps are:

• Increase Ventilation: Open windows or run exhaust fans.
• Source Control: Seal or remove the off-gassing item (like a half-used paint can).
• Air Purification: Use an air purifier with a high-grade Activated Carbon filter.

• CF-20 air quality monitor(Standard): Provides real-time, high-accuracy air quality monitoring on an LCD screen. It is designed for immediate "at-a-glance" readings.
• CF-20 DL data logging air detector (Data Logger): Includes all features of the standard model but adds an internal memory chip. It can record and store up to one year of history data, which you can export to a computer as a CSV/Excel file for professional analysis.

Both the CF-20 and CF-20 DL are 10-in-1 monitors that track:

• Carbon Dioxide (CO2): Uses NDIR technology for precision.
• Particulates: PM2.5 and PM10 (Fine dust and allergens).
• Chemicals: Formaldehyde (HCHO) and TVOCs.
• Environment: Temperature, Humidity, AQI (Air Quality Index), Date, and Time.

For the most accurate results, the sensors need to establish
a baseline:

1. Take the device to a well-ventilated area or outdoors.
2. Power off the device, then long-press the three buttons together to enter calibration mode (a 200-second countdown will appear).
3. Leave the device in fresh air for at least 4 to 6 hours during its first use to stabilize the sensors.

The CF-20 series uses medical-grade NDIR (Non-Dispersive Infrared) technology for CO2 and Laser Scattering sensors for PM2.5.

• CO2 Accuracy: ±50ppm or ±5% of reading.
• PM2.5 Accuracy: ±10µg/m³.
• Lifespan: The industrial-grade CO2 sensor is rated for a service life of up to 15 years, significantly longer than standard consumer electrochemical
  sensors.

Air is not a static "soup"; it moves in
micro-climates. One device may be closer to a window (higher O2) or a corner
with stagnant air (higher CO2). Additionally, all professional sensors have a "tolerance" (margin of error). If two units are within 10% of each other, they are both functioning perfectly.

400ppm is the global baseline for "fresh outdoor air." The device is calibrated to treat 400 as the "zero point." If your indoor air is excellent or you have windows open, the reading will stay at 400. To test the
sensor, breathe directly onto the back of the unit; you should see the number
spike immediately.

Total Volatile Organic Compounds (TVOCs) are gases emitted
from solids or liquids. Common sources include:

• Household: Cleaning sprays, air fresheners, and perfumes.
• Building: New furniture (off-gassing), paints, and carpets.
• Human Activity: Cooking oils and even high concentrations of human breath in
  an unventilated room.

The TVOC sensor needs a "clean air" reference to work correctly. Upon first use, the device requires a 24-48 hour
"burn-in" period to stabilize. During this time, the sensor learns the baseline of your environment to ensure future spikes are reported accurately.

Yes. The most effective steps are:

1. Ventilation: Open windows to flush the air.
2. Source Control: Identify the "smell" or source (like a new rug) and move it to a ventilated area.
3. Purification: Use an air purifier with a thick Activated Carbon filter.

Yes.Unlike many monitors that group HCHO into a general VOC score, the CF-20 has a dedicated HCHO sensor to help you specifically monitor the off-gassing from building materials and pressed-wood furniture.

Absolutely. The Laser PM2.5 sensor is specifically designed to detect the microscopic particulates found in smoke. The CF-20 is an essential tool for residents in wildfire-prone areas to know when to seal windows and run air purifiers.

The device does not "count" mold spores, but it monitors the Mold Growth Index—specifically high humidity (>60%) and stagnant air (high CO2). By keeping your humidity between 30-50%, you can effectively prevent mold before it starts.

1. Connect the CF-20 DL to your PC or Mac using the supplied USB-C data cable.
2. The device will appear as a "Removable Drive" (like a USB stick).
3. Open the folder to find the CSV/Excel file. This allows you to create professional reports for landlords, employers, or health specialists.

• Ensure you are using the original cable provided in the box; some charging-only cables do not support data transfer.
• The device only generates a file once it has recorded at least one data point. Ensure the device has been powered on and monitoring for some time before
  exporting.

Yes. The CF-20 series features an Auto-Dimming function. After approximately 4 minutes of inactivity, the screen will dim to a low-light mode so it doesn't disturb your sleep while it continues to monitor the air.

The device features a 2600mAh rechargeable lithium battery.

• Cordless Use: Expect 4 to 8 hours of continuous monitoring on a full charge.
• Long-Term Use: For 24/7 monitoring, it is recommended to keep the device plugged into a standard 5V USB power source (like a phone charger).

Yes. When an alarm is triggered (e.g., CO2 levels exceed the healthy threshold), the display will flash red and beep. You can short-press the power button to mute the audible buzzer at any time.

If your readings seem "sticky" or inaccurate:

1. Power off the device.
2. Long-press the three buttons together to enter calibration mode (a 200s countdown will appear).
3. Leave the device in a well-ventilated, fresh-air environment for 4–6 hours.This will reset the CO2 and TVOC zero-points.

The device contains a high-capacity battery. During charging or heavy use, internal heat can cause the temperature reading to rise by 1-2°C. For the most accurate "ambient" temperature, use the device while it is unplugged or placed
in an area with a slight breeze.

400ppm is the standard concentration of CO2 in fresh outdoor air. Because this is
the natural "floor" for our atmosphere, the device is calibrated to show 400 as the cleanest possible baseline.

Chemical sensors (TVOC/HCHO) require a "burn-in" period. If the device has been in a box or a stagnant environment for a long
time, the sensors may take 24–48 hours of being powered on in fresh air to become fully responsive.
