Environmental Control Units
The following sections briefly describe the environmental control units for the AR Rheometers.
Peltier Plate
The Peltier Plate is the standard temperature control system for the rheometers. It uses the Peltier thermo-
electric effect to control the temperature accurately, with rapid heating and cooling. The plate consists of a
copper disc, with hard chrome plating on the upper surface. A Pt100 temperature probe is embedded in the
disc, in thermal contact with it and close to the surface. Copper is used as the disc material for its very high
thermal conductivity, ensuring negligible temperature gradients across the surface of the plate. The hard
chrome plating prevents mechanical or chemical damage to the plate.
Refer to the Peltier Plate Getting Started Guide
for additional information.
