ThermElc TE-04 Buffered Probe temperature digital data logger is a continuous temperature monitoring device mainly used in pharmaceuticals, vaccines shipping and storage. The detachable propylene glycol bottle external temperature probe as a thermal buffer would reflect more accurate and stable readings, which is to simulate the vaccine storage condition. Max/Min value display on the large LCD screen makes monitoring easy and convenient.
The data logger gives audible and light alerts when the temperature is out of setting range. The logging interval can be customized depending on your need for convenience.
- Multi-use temperature and humidity data logger records up to 35,000 temperature points
- 1 external detachable buffered temperature probe with glycol vial attached(3 meters)
- Wide temperature measurement range from -40℃ to 185℃. Accuracy up to ±0.5℃;
- Pre-programmed sampling rate and alarm limit in the free software.
- Multi-Alarm notifications: Buzzer, LED Indicators, Screen Display.
- The large LCD screen, convenient for direct viewings of key information including temperature, alarm status and etc.
- 1 year warranty.
How Does a Thermal Buffer such as Glycol Provide More Accurate Readings?
According to the CDC guidelines for vaccine storage, a detachable probe in a bottle filled with a thermal buffer, such as glycol, more closely reflects vaccine temperatures. As indicated before, vaccine temperatures have been found to be more thermo-stable than air temperature which fluctuates with door openings/closings and defrost cycles. Suspending a probe in a sealed glycol bottle helps to prevent intermittent air currents from throwing the readings off and averages out the temperatures of the surroundings, consequently reflecting the actual temperature of vaccines inside refrigerators.
