Humidity Controller
IM3700
Series Temperature Humidity controllers are Microcontroller
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
technique.Useful in pharmaceutical industry, environment
chambers, green house rooms etc.
