Libratherm offers low cost temperature and humidity indicators & controllers, which are best suited for indicating and controlling of the temperature and relative humidity for generalpurpose application. These models accept input from the std. Rtd [pt-100] temperature sensor for temperature and the capacitive type rh sensor for sensing relative humidity. The instrument displays the temperature o in the range 0.0-100.0 c and humidity in the range 0.0 - 100.0 rh on 4 digit 7-segment red led display. The on/off control action is provided for controlling temperature and relative humidity. For example to maintain the controlled climatic condition in a room to maintain the desired level of temperature and %rh, these control outputs can be used to regulate the air heater, air conditioner, de humidifier or moisture/steam / water vapor generator. The control output can also be in the form high or low alarm to indicate the high or low level of temperature / %rh from the desired set points.
Features of the digital temperature & humidity indicator / controller are:
Microcontroller based design.
Elegant appearance and compact in size.
Designed for industrial use.
