Huber’s Refrigeration bath circulators are suitable for controlling the temperature of externally connected applications and thermoregulation of objects directly in the thermostat bath. Typical applications are: photometers, refractometers, viscometers, double-jacketed reaction vessels and autoclaves. The units can be used in mini-plants and kilo laboratories, for determining the freezing point, for deep temperature calibration, for petroleum tests, for temperature control of measuring devices and experimental setups as well as for materials testing and quality control. Depending on the model, the equipment is able to meet the highest demands; this is ensured by the professional range of functions available on the Pilot ONE controller, such as a colour TFT display, programmer, Pt100 external probe connection, calibration, calendar/clock functions, autostart, RS232 interface as well as extensive safety and warning functions. One further plus point is the electronic upgrade for function extensions using a unit specific e-grade code. This activates additional functions such as the programmer, TAC cascade controlling, temperature ramps, user menus, calendar start, graphic display and process control. The units are made from high quality stainless steel and have a thermoregulated cover plate to avoid condensation and build up of ice. The bath vessel has a volume of 5 litres and can be emptied via the drain fitting over the front.
