temperature and humidity recorder
Wall mounted digital temperature and humidity recorder
Wall mounted digital temperature and humidity recorder adopts digital temperature and humidity sensors and low-power MCU technology. The products have the characteristics of short response time, high accuracy and long term stability. The product has the function of 485 output and field display, and has the function of recording and storing. It can not only record and store the local data, but also record the record data at the same time.
The method has the advantages of good consistency, long service life, fast response, small temperature coefficient, wide range, high precision, good stability and small annual drift;
Interchangeability is good, compatible with a variety of brands of temperature and humidity sensors on the market, sensors can be interchanged;
The transmitter is fully calibrated and output without calibration. It can be used for simultaneous detection of multiple points while the longest transmission distance is 1200 meters.
