Criterion Temperature Benchtop Chambers
The Criterion temperature chamber series provides an economical and space-saving solution for a variety of temperature testing requirements. The chamber's interior size is 3.5 inches wider than traditional benchtops, yet the exterior is 20% narrower. The BTZ-133 chamber uses 115V power, meaning no special power hook-ups.
- Lowest temperature: -20, -35, or -70C (-4, -35, or -100F)
- Highest temperature: 180C (354F)
- Chamber sizes: 1.5 or 4 cubic feet
- Fully programmable with Watlow F4 controller
The extended temperature ranges of the Criterion 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 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.
The conditioning components are laid out in a vertical configuration to save bench space. |
The Criterion chambers respond quickly to setpoint changes. The BTZ-175 can |
