NOVOTHERM
Temperature Control System

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.
Features
- 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

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.
