Temperature and Humidity Transmitter with Digital LCD Display

Temperature and humidity transmitter with LCD display converts the air temperature and humidity into 4-20mA standard signal, and mounts in duct or on the wall.

Application: Temperature and humidity transmitter is widely used in meteorology, tobacco, chemicals, medical and health, food industry and other occasions that need air temperature and humidity measurement and control.

Built-in switch setting for measuring range of temperature:

Tips: Why should temperature and humidity sensor/transmitter be calibrated regularly?

1. The temperature and humidity sensor cannot be sealed and protected.
2. The measuring part is always in contact with dust and chemicals in the measuring medium.
3. The electrical part of the temp and humidity sensor will change due to the passage of time, temperature change and mechanical vibration.
4. The above factors will cause the temperature and humidity sensor to drift.

The purpose of calibration:

1. Determine the error of the indication value, and determine whether it is within the expected allowable error range.
2. Get the report value of the deviation of the nominal value, which can adjust the temperature and humidity sensor or correct the indicated value.
3. Ensure that the value given by the temperature and humidity sensor is accurate to achieve traceability.
4. Calibration is the execution of a predefined process to determine the relationship between known input values and output values, which is carried out under specified conditions.
