Criterion Benchtop Chambers

The Criterion temperature/humidity 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)
  • Humidity range: 10 to 95% RH
  • 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 refrigerations 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.

ESPEC can add safety options for testing lithium-ion batteries or other products. See the options tab for a list or the Battery brochure below.

ESPEC Expertise in Humidity Control

Controlling humidity in a small environmental chamber can be especially challenging. ESPEC expertise in humidity control brings intelligent design that is carefully integrated into the Criterion chambers. The humidity subsystems are designed for reliability, convenience, and performance:

  • The steam generator allows expanded humidity range and is easy to maintain.
  • A separate de-humidification coil improves low humidity control and range.
  • Wet-bulb humidity sensor is a primary measurement method” for accuracy. It is also economical, easy to maintain, and reliable because it has no risk of failure due to over-saturation. (Read why analog is preferred over digital.)
  • Direct water supply connection is standard, with options for water filtering and recirculating water tank.
