Humidity Controller by Ajinkya Electronic Systems

Humidity Controller is micro-controller based highly versatile controllers for combined control of temperature and humidity. This Controller is available with PID control algorithm. Control parameters are user configurable on site. These controllers can accept input from the different type of Humidity sensors as well as RTD sensor for Dry Bulb / Wet Bulb measurement technique.

They are useful in pharmaceutical industry, environmental chambers, greenhouse rooms etc.
