Criterion Temperature Benchtop Chambers

BTZ-133 with optional window

The ESPEC Criterion benchtop temperature chamber series provides a economical and space-saving solution for a variety of temperature testing requirements. The chamber's 1.5 cu. ft. interior size is 3.5 inches wider than traditional benchtops. The BTZ-133 chamber uses 115V power, meaning no special power hook-ups.

The BTZ-175 chamber models can achieve 5°C per minute temperature change rates. All done with cascade refrigeration, so no liquid nitrogen supply is needed. A 50mm (2") diameter cable port in the left side of the chamber allows wires and cables to be run to your samples. 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.

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 save 30 minutes or more per cycle.
