MicroTherma 2T Accepts Type T thermocouples ±0.2°C meter accuracy Self-calibrating circuitry Includes Hold, Max and Min functions Switchable °C or °F
The MicroTherma 2T is compact, easy-to-operate and reliable. A New version of the popular MicroTherma Series makes use of a unique line of high-precision type T thermocouples. The combined result gives you the best accuracy available in handheld thermocouple measurements. Self-diagnostic recalibration takes place each time the meter is powered on. Every time you check the calibration of the MicroTherma against an external standard, you’ll find it within spec – no adjustments required. Each MicroTherma includes a traceable cal certificate with actual test data. Although the precision thermocouples provide the best possible accuracy for interchangeable probes, the MicroTherma also allows a “system-cal” adjustment to offset any probe errors. Choose probes from our broad line of type T thermocouples.

	110 to 230v AC line operation
	Control Range of -100 to +400^oC
	Resolution 0.1^oC

The new TCAT-2 general purpose PID Autotuning Controller 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, TCAT-2 Controller is provided in several versions. The model specified depends on whether a laboratory has a general or specific need for the controller.

Model	Dimension	Price
TCAT-2AC	This version controls only AC powered heating or cooling devices such as a heat lamp.	$915.00/Each
TCAT-LV	This model provides a low voltage DC output for electrically sensitive applications where AC frequencies might interfere with other monitoring devices. It comes standard with a built in DC power.	$1,010.00/Each
TCAT-2DF	This is a combination version which includes both an AC outlet for controlling primarily resistance loads such as heat lamps, AC powered warming blankets and a low-voltage, low noise” DC output for heating pads. This version allows you to control a variety of different loads.	$1,135.00/Each
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 (call for details) may also be used depending on the specific application. All instruments are designed to operate on a 110V or 230V AC supply.
