What is a TEMPERATURE HUMIDITY TEST CHAMBER ?
ATMARS AH series reach-in / compact environmental test chambers can create a wide range of temperature and relative humidity levels with the maximum being -80℃ to 200℃ (standard models: -70℃ to 150℃) and 1% to 98% RH (standard models: 20% to 98% RH).
Whether you need to perform temperature cycling tests or expose your specimen to a steady state temperature environments, our chambers will maintain precise and accurate temperature/humidity control throughout your test.
And you can select from a variety of sizes, ranges, and options to meet your specific environmental testing requirements. Users will enjoy high quality & reliability, the ease of use, low maintenance requirements of our temperature humidity chambers and allow you to maximize product testing efficiency without sacrificing quality.
In additional to being much more functional, ATMARS test chambers have a sleek, beautiful, contemporary appearance.
ATMARS reach-in standard models workspace volumes include: 80L, 100L, 150L, 225L, 408L, 800L, 1000L to walk-in /drive-in sizes. And interior dimensions can be customized according to specimen sizes and your testing requirements.
