The PolyScience Division of Preston Industries, Inc. introduces a highly sophisticated, multi-function temperature controller. Designed for heating and cooling applications requiring precise, multi-level temperature control, the PolyScience Programmable Controller can be programmed with up to ten different time/temperature profiles, each of which can have as many as 50 temperature steps. Fluid temperature, setpoint and other important operating parameters are displayed simultaneously on an LCD screen and other standard features include multi-language menus, pump speed control, remote temperature probe capability and user-set temperature alarms. The controller is available on PolyScience six-, 13- and 28-liter circulators.
