Contained all in one enclosure, Oven Industries Inc.'s thermoelectric module benchtop temperature controller can be plugged into the wall as a self-contained system with its own power supply. The 5R6-900 unit can also be used universally, which allows the user to access the devices wherever they are located. The solid-state MOSFET bidirectional compact bench-top unit features an internal power supply and is also capable of loading currents up to 10 A. User-friendly and PC-programmable, the 5R6-900 easily connects to a computer through the electrically isolated RS232 communications port, according to the company. The PC can be used as a connector, and the temperature controller can stand alone once the desired parameter settings are in place. The 5R6-900 is suitable for use in universities, science laboratories, and any businesses that specialize in temperature control.
