Temperature Only Test Chambers

High And Low Temperature Test Chamber

Temperature chamber models designed to save lab space

The Temperature chamber series provides an economical and space-saving solution for a variety of temperature testing requirements.

Lowest temperature: -20 or -70°C (-4 or -100°F)

Highest temperature: 180°C (354°F)

The extended temperature ranges of the Standard series make testing at extreme conditions possible without buying a larger, stand-alone chamber. Two chamber sizes are available, as well.

The programmer includes a temperature alarm as just one part of Grande's three-tiered over-temperature protection system. A thermal fuse and a user-set independent limit are also included. In addition, a specimen power terminal allows the user to safely operate powered equipment inside or with the chamber.
