Temperature Humidity Controllers are micro controller based highly versatile controllers for combined control of temperature and humidity. Controller is available with PID control algorithm. Control parameters are user configurable on site. Controllers are available which can accept input from different type of humidity sensors as well as RTD sensor for dry bulb / wet bulb measurement techniques. Useful in pharmaceutical industry, environment chambers, green house rooms etc.
