High Temperature Constant Humidity Test Chamber ToronTTHC-250G
High Temperature Constant Humidity Test Chamber ToronTTHC-250G is designed for advanced material testing across academic institutions, research centers, and industrial facilities.
This chamber supports tests under both high and low temperature conditions, enabling tensile, compression, bending, and shearing evaluations on metal and non-metal materials. It’s especially suitable for specialized industries such as plastics and rubber.
Engineered for flexibility, it works in tandem with your existing testing system—no modifications to the main testing machine are needed. Built-in tracks allow the chamber to be easily moved for ambient temperature tests, simplifying operation and saving time.
Key Features
-
The chamber exterior features a durable electrostatic powder-coated finish, while the interior is constructed from mirror-finished stainless steel. An observation window with an anti-fog function is built into the front door, along with interior lighting to facilitate clear monitoring during tests.
-
The temperature control system uses PID control with a display accuracy of 0.1°C, ensuring precise and stable temperature regulation.
-
A centrifugal fan enables forced air circulation within the chamber, maintaining uniform airflow and ensuring temperature consistency that meets test standard requirements.
-
The chamber is equipped with a built-in guide rail system, allowing smooth movement in and out of the main testing machine space.
-
“U”-shaped cutouts on the top and bottom ends, along with integrated seals, make it easy to position the chamber within the testing machine without compromising the test environment.
-
A constant humidity system is included, enabling tests to be conducted in a controlled temperature and humidity environment.
