ATC1000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The DC heater is extremely quiet in terms of electromagnetic radiation. This is essential in electrophysiological recordings which are very sensitive to electromagnetic interference.

The controller uses proportional, integral, and derivative (PID) technology in adjusting the DC voltage output. Compared with switched on/off type controllers, PID controllers provide a much more precise and stable control of temperature. The PID approach is also more immune to the variation of the experimental conditions such as change in animal size and unexpected disturbances.

The controller has dual temperature sensing inputs.

• The Probe input is used to monitor the rectal probe to control the animal temperature.
• The other is input is labeled “Output,” because it connects with the heater. It is used to monitor an internal temperature sensor in the heating plate (available separately) to prevent the localized hot spots under animal.

The ATC features an auto tuning function that utilizes a fuzzy-logic algorithm to optimize settings automatically. Parameters may also be set manually. The temperature resolution of the controller is 0.1°C. The rectal temperature probe has a 6-ft ultra-flexible shield cable and an RTD sensor.

Heating elements

The metal heating plate includes a built-in temperature sensor. Compatible with stereotaxic systems, its rigid, flat surface fits under the U-frame. All plates are washable with water and detergent.

A heating plate (order number 502195 or 502196) and a probe (order number 502197 or 503524) are required for use with this unit. Please see the Accessories tab.
