These controllers are ideal for on/off control applications where a digital display and an adjustable deadband are needed over a limited temperature range. Use with packaging equipment, food cooling and chilling equipment, and more. Each controller has three push buttons for programming parameters including set point, deadband, cycle time, and ambient probe adjustment. Programmable password protection prevents accidental changes to settings. Multiple units can be set with the same program with the use of a “configuration key” (sold separately). The bright 3-digit LED display is easy to read even in dim areas Controllers are available with a thermocouple or thermistor input; the thermocouple version features two selectable alarm conditions and internal buzzer. The FM-approved limit models include field-selectable automatic or manual reset, as well as front-panel or external input reset option. Order probes separately.

  • Q:

    I am trying to design a homeostatic environment chamber for a senior design class project. My range of temperature I need is anywhere from 35-39 degrees Celcius. I am using a k-type thermocouple and a glass heater (127.8 mm x 85.6 mm). Will this type of temperature controller work for my design I am making?

      This controller is a simple on/off controller. The range fo 35 to 39 degrees Celsius is well with in the range of control and this should work just fine. However this version is a 230V version. The 115V version is available as catalog number 93520-02.
