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.
