Temperature Only Test Chamber/High And Low Temperature Test Chamber LETO

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

  • Temperature Only Test Chambers

    • 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.
