Explosion-proof temperature and humidity recorder

Explosion-proof temperature and humidity recorder temperature and humidity detection principle: uses digital temperature and humidity sensors, packages the thermal resistor and humidity-sensitive capacitor into a small chip, uses full-scale multi-segment calibration, and stores the calibration data into the chip.

The Explosion-proof temperature and humidity recorder is mainly used to monitor and record the temperature and humidity data of food, medicine, chemical products and other products during storage and transportation.
