Tips: Advantages of temperature and humidity sensor/transmitter
- Temperature and humidity sensor/transmitter is extremely accurate, which can achieve accurate measurement and control of temperature and humidity, so as to ensure product quality, improve production efficiency, save energy, production safety and play other roles.
- It can automatically alarm. When the measured value exceeds the upper limit alarm value, the temp and humidity monitoring machine will automatically alarm. In addition, you can also use the mobile phone remote real-time query temperature and humidity values, which is easy to achieve unattended.
- Its shell is waterproof and anti-condensation, which can work normally in bad environment.
Industrial temperature and humidity transmitter with LCD display adopts digital temp and humidity sensor AM2305 and convert the air temp and humidity into 4-20mA standard signal. It has dust protection probe and metal filter screen, measuring range from -40 to +100℃, stable and reliable.
