The PID temperature controller model WSD-30A is featured with low voltage direct current (DC) output for using with a low noise DC-powered heating plate. It allows accurate electrophysiological recording with minimal electromagnetic field interference (EMF). This controller offers higher sensitivity and precision than the RTD and thermocouple sensor based controllers by using thermistor type sensor. It is equipped with a rectal temperature probe suitable for both mice and rats, and a temperature senor on the heating plate for limiting the maximum surface temperature to avoid over-heating or burn injury. The setting for the maximum surface temperature limit can also be adjusted and viewed by the user. Please refer to the usermanual before using the system. Below is the summary of specifications.
