The Criterion temperature chamber series provides an economical and space-saving solution for a variety of testing requirements. The chamber's interior size is 3.5 inches wider than traditional benchtops, yet the exterior is 20% narrower. Some models use 115V power, meaning no special power hook-ups.
- Lowest temperature: -20 or -70°C (-4 or -94°F)
- Highest temperature: 180°C (354°F)
- Chamber size: 1.5 or 4 cubic feet
- Touch-screen Watlow F4T programmer with Ethernet access
The four cubic foot workspace is the largest to be found in a benchtop unit, while requiring less footprint than even smaller comparable chambers. The vertical configuration saves bench space, plus the refrigeration’s ventilation design allows installation against a wall for even more space savings.
The programmer includes a temperature alarm as just one part of ESPEC'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.
