High and Low Temperature Chamber for Thermal Cycling Test Engine
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.
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.
