A unipolar temperature controller, the RHM5K-CH provides precision control at off-ambient temperatures. Using a PID control loop to drive resistive heaters or thermoelectric coolers, the component offers a high level of stability and can supply up to 5A. Its 12-turn trimpots control temperature set point, proportional gain, and output voltage limit and a single 10-pin terminal strip provides access to the dc supply, sensor, resistive heater, and measurement connections. Features include a less than 0.003 °C stability (24-hour). WAVELENGTH ELECTRONICS INC., Bozeman, MT. (406) 587-4910.
