Criterion Temperature & Humidity Benchtop Chambers
Our largest benchtop humidity chamber
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. The BTL-433 model uses 115V power, meaning no special power hook-ups.
Lowest temperature: -20 or -70°C （-4 or -100°F）
Highest temperature: 180°C （354°F）
Humidity range: 10 to 95% RH
Chamber size: 4 cubic feet
Fully programmable with Watlow F4 controller
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.
HONGZHAN Expertise in Humidity Control
Controlling humidity in a small environmental chamber can be especially challenging. HONGZHAN expertise in humidity control brings inligent design that is carefully integrated into the Criterion chambers. The humidity subsystems are designed for reliability, convenience, and performance:
An external steam generator allows expanded 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.
