The SRTH-2A temperature and humidity monitoring device is mainly designed and manufactured for monitoring the temperature and humidity of outdoor electrical terminal boxes, high-voltage distribution devices, and switch operating mechanisms, effectively preventing corrosion of electrical terminals, accidents caused by insulation creepage, and structural failures caused by low temperature environments.  

1. Using software standard technology to compensate for voltage temperature drift counting errors and component nominal errors, the measurement accuracy is high and not affected by usage time. 2. The digital display alternately displays real-time temperature and temperature environment monitoring values with a cycle of 2 seconds, and conveniently controls temperature and humidity control values through three functional keys.
3. Humidity setting range: 40% to 90% RH
4. Temperature setting range: 5 ℃~25 ℃
5. Humidity control error: ≤ 5% RH
6. Temperature control error: ≤ 20
7. Aluminum alloy comb shaped heating rated power: 50W~500W
