Temperature Control System

Novotherm is an economical turnkey temperature control system for applications in material research. In contrast to the cryosystems, Novotherm works with air instead of liquid nitrogen from ambient to 400 °C. It can be used with all Novocontrol sample cells for dielectric and impedance spectroscopy.

The system sets or ramps the temperature of the sample under test. It is modular and can be combined with any Novocontrol BDS dielectric or impedance spectrometer.

Novotherm was designed for easy, safe and fully automatic operation enabling computer controlled experiments over several days without supervision as required for low frequency measurements.


  • high quality turn key temperature control system
  • temperature range ambient ... 400 °C
  • temperature ramps from 0.01 .. 20 °C/min
  • 0.1 °C temperature accuracy and stability
  • temperature overshooting after setpoint step typically < 1 °C
  • stabilization times typically < 5 minutes (for 0.1 °C stability)
  • microprocessor controller with 24 bit ADC and GPIB communication port

Principle of operation

Principle of Operation
The intended temperature (setpoint) is set at the controller unit either manually or by computer control. The actual temperature at the lower plate of the sample electrode is measured by a Pt100 temperature sensor. A high pressure fan creates an air stream which passes a heating element and flows around the sample under test. The controller adjusts the air stream temperature in order to match the actual sample temperature to the setpoint.
