Huber has developed small cooling thermostats, the Huber Ministats, which have adequate power to thermo-regulate refract meters, photometers, lab extraction hoods, mini plants, reactor vessels, distillation apparatus and viscometers.

The kits could be utilized for controlling closed applications externally or else the objects could be thermo-regulated directly inside the bath.
Three models are available, either as water or air cooled versions, whose working temperatures range between -45C to 200C, while cooling capacities of 600 W could be obtained. The maximum environmental temperature allowable for continuous operations is 40C. Optimum circulation is permitted by a variable speed suction/pressure pump, which could be controlled by utilizing an optional pressure sensor that protects fragile glassware.
The CC-Pilot controller is available with TFT display, RS232, six language options, alarm signals, adjustable safety limiting values, auto-start, clock & calendar functions and sensor calibration. It is available in three software options, which could be electronically upgraded easily for extending functionality and for activating features such as cascade control, programmer, graphic display, calendar start, user menus and ramp function.
