Specification and model: mhrmv03

1、 Scope of application:
Storage, tobacco, power, pharmaceutical and other industries; temperature and humidity instruments, plus
Wet equipment, dehumidification equipment, high-grade air conditioning and other products.  
2、 Electrical parameters:
1) Humidity sensing element: waterproof polymer humidity sensitive resistor
2) Temperature sensor: NTC thermistor, 10K ± 1%, B = 3435k ± 1%
3) Power supply: 5VDC ± 5%
4) Current consumption: 5mA max. (2mA AVG.)
5) Measurement range: humidity: 0% ‐ 100% RH temperature: - 20 ℃ ~ - 80 ℃

6) Measurement accuracy: humidity: ± 3% RH (25 ℃, 60% RH, input voltage = 5V) temperature: ± 1 ℃

7) Humidity output signal: 25 ℃, input voltage = 5V, output voltage unit (V);


5、 Application notes:
1) Avoid touching the moisture sensing elements
2) Long term use of hydrochloric acid and other gases containing strong sulfur dioxide should be avoided;
3) Avoid reverse connection of positive and negative poles of power supply;
6、 Note: the thermistor with different central resistance and b value can be selected according to the needs
