ENVIRONMENTAL CHAMBERS
Temp.&Humidity Environmental Chamber
Temperature and Temperature/Humidity test chambers
provide superior performance over a wide range of
applications. From prototype to durability to product
component screening tests, the chambers has been
designed to meet quality standards while still offering
flexibility uniformity and control accuracy for cost-effective
testing. Available in a multitude of chamber sizes, MRC
is sure to have the exact chamber that best meets your
environmental test criteria. For testing smaller products or for
customers with limited space, MRC offers chambers starting
at 36Liter capacity up to 800 Liters. MRC Test Chambers are
able to perform both high and low temperature tests. Many
of these chambers have a temperature range of -70°C to
+150°C. Hermetically sealed compressors provide moderate
temp. change rates while allowing the chamber to
consume less power than comparable chambers. Temp./
Humidity models are equipped with a reliable, accurate
and efficient full range humidity system capable of
simulating conditions from 20 to 98% RH.

the compressor will only be disconnected if cooling
capacity has not been required for a prolonged period
●
Heating system: low mass electric resistance heater is
located directly in front of the recirculating air blower. The
PID microprocessor controllers with the solid state relays
allows extremely precise and constant control.
