Heating bath circulation thermostats with a stainless steel bath allow the temperature control of internal and external thermoregulation tasks. Items can be directly thermoregulated by placing them in a thermostat bath and the control of externally connected applications is also possible. The units are suitable for a number of typical temperature control tasks such as sample temperature control, materials testing, quality control, etc. The devices are fitted with overtemperature and low level protection in line with Safty Class III/FL according to DIN 12876. A powerful pressure/suction pump ensures optimal circulation and temperature homogeneity in the thermostat bath and also allows temperature control of externally connected applications.

The new multi-touch controller Pilot ONE offers a brilliant 5.7 touchscreen with graphic functions and a comfortable navigation menu. All important operating parameters and temperature values are neatly displayed on the touchscreen. Thanks to the new favourites menu, the one-click operation and the integrated technical glossary the operation is very easy, just like on a smartphone. Integrated USB and Ethernet ports allows connection to a PC or network, e.g. for remote control or data transmission.
