Model TC-1000 Temperature Controller monitors and controls the body temperature of small animals. This instrument features a low-voltage DC proportional controller to provide artifact-free heating using a resistive heating pad. The smooth Proportional-Integral-Derivative (PID) control eliminates the electrical transients common to on/off type controllers. A front-panel LCD panel displays the current body temperature, the targeted set-point temperature, alarm settings, and a heater power bar graph. An analog output provides a linear voltage corresponding to temperature.
The controller uses standard YSI-400 series (or compatible) thermistor probes. These interchangeable probes are available from CWE in a variety of sizes to suit the animal being monitored. Resistive heating blankets are available in mouse, rat, or cat size. Other resistive-type heating devices (such as immersion heaters) can be connected, as long as the current draw is less than 3A at 12VDC. Heater currents up to 10A are possible using an external battery or power supply, accessible using binding posts on the rear panel.
Operation: The TC-1000 controller is simple to operate. After plugging in the probe and heating blanket, the animal’s temperature is shown on the display. The adjustable set-point temperature and alarm band is also displayed, both being adjustable using a single knob. An over/under temperature alarm with adjustable hysteresis is pushbutton activated. The unit automatically detects fault conditions such as a defective or disconnected probe or heating blanket. Initial setup procedure selects animal size to provide optimal control to prevent accidental overheating.
