HJ Series High/Low Temperature & Humidity Test Chamber

HJ Series High/Low Temperature & Humidity Test Chamber

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

Designed to handle a broad mix of testing needs, these chambers make it possible to replicate everything from steady high temperatures to fluctuating cycles of heat, cold, and moisture. They’re suitable for labs and production facilities that need consistent conditions for checking product stability, durability, and performance under demanding scenarios.

Typical Test Applications
  • High-temperature exposure
  • Low-temperature testing
  • Constant temperature and humidity conditions
  • Alternating high and low temperatures
  • Combined cycles of temperature and humidity
Our temperature and humidity test chamber models comply with the following standards:
  • EN IEC 61000-6-2:2019
  • EN IEC 61000-6-4:2019
  • EN 61010-1:2010+A1:2019

Condensing method Air-cooled/water-cooled

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.
