EJ Series High/Low Temperature & Humidity Test Chamber

Environmental simulation chamber for testing materials by simulating conditions at desired temperature and humidity levels

These chambers provide an economical option for simulating a variety of temperature and humidity conditions. They are suitable for high- and low-temperature tests, constant climate exposure, and alternating cycles to check how materials and components respond to changing environments.

Features
  • Quiet design with maximum noise levels of 60 dB(A) or less
  • Stable operation, low failure rates, and excellent cost-effectiveness

Condensing method Air-cooled/water-cooled
(Models ending with “A” are configured as air-cooled,while those ending with “W” are water-cooled versions. For example,ER-02JA refers to an air-cooled chamber,and ER-02JW indicates a water-cooled chamber.)

For air-cooled models, performance specifications are based on an ambient temperature of +25 °C and relative humidity of ≤85% measured with the chamber empty. For water-cooled models, reference conditions are an ambient temperature between +15 °C and +35 °C, relative humidity of ≤85%, and cooling water temperature of ≤+28℃, also measured without test samples inside the chamber.

Start by thinking about the materials you need to test and the exact conditions you plan to recreate. Once you share those details with us, our team can suggest a test chamber that matches your testing process and performance targets.

Yes. To maintain stable operation, it’s important to use purified water with controlled levels of resistivity, conductivity, and total dissolved solids (TDS). This helps avoid mineral buildup and keeps humidity readings accurate.

Of course. If you need official verification, we can arrange calibration reports issued by certified third-party labs to confirm the test chamber’s performance.

Both cooling methods are effective, but your choice depends on your facility layout and utility connections. If you’re unsure which one fits your environment best, our specialists will walk you through the pros and cons of each option.
