Product Description:

Two different models, both equipped with low liquid-level controllers in accordance with the latest ASTM specifications. Two-unit water analog-controlled water bath can be flush mounted in a table top if desired, and is equipped with an overflow standpipe/drain to maintain the proper depth when the pressure vessels are inserted, and a plated brass reflux condenser to minimize evaporation loss.

The four/six-unit model can be used with water or oil as a bath medium, and has microprocessor temperature control that provides quick temperature stabilization without overshoot. Dual LED displays provide setpoint and actual temperature values in C/F format. A built-in overtemperature control circuit interrupts power should the bath temperature exceed a programmed cut-off point. Both models feature double-wall insulated construction with stainless steel tanks, support racks and port covers. Order thermometer separately. The four/six unit model can be ordered with interchangeable racks for performing the ASTM D942, ASTM D323 and D1298 test methods.
