Our TCAT-2 family of general purpose PID Autotuning Controllers provides accurate temperature control in a variety of laboratory applications. Combined with a heat lamp or heating pad, the TCAT-2 may be used to maintain the body temperature of anesthetized animals during surgery or stereotaxic procedures. Small animal cages are easily warmed with a heat lamp. The TCAT-2 may also be used in cooling applications, such as to control independent perfusate cooling systems. Realizing that laboratory applications are diverse, Physitemp can provide several versions of the TCAT Controller. The model specified depends on whether a laboratory has a general or specific need for the controller


This version controls only AC powered heating or cooling devices such as a heat lamp. It is the least costly.

For low voltage models with DC output for electrically sensitive applications where AC frequencies might interfere with other monitoring devices see TCAT-2LV and TCAT-2DF.

All TCAT-2 versions may be used with any of our extensive line of accurate Type T thermocouple probes, which act as the temperature feedback sensor. Most commonly used are the RET series of animal rectal probes, but the IT series of implantable flexible probes and MT series of needle probes may also be used depending on the specific application. All instruments are designed to operate on a 110V or 230V AC supply. Must specify voltage when ordering.

The unit comes in a durable baked enamel painted aluminum housing. Adjustable front feet allow the user to raise the front of controller to provide a more convenient viewing angle.

A heat/cool switch is provided when using the controller with cooling devices such as small refrigeration compressors or thermoelectric stages. In the cooling mode it inverts the control function and shuts off the load when feedback sensor temperature falls below the set point. A small lamp on the front of the control unit indicates when power is being applied to the load.

The TCAT-2 is simple to set-up; connect the feedback sensor to the animal and to the back of the controller, connect the heating pad, blanket, lamp or cooling device to the appropriate outlet on the rear of the controller. Adjust the set temperature as required (lower green display) according to the instruction label on top of the instrument. The set temperature is stored in memory after the unit is switched off.
