EW Series High/Low Temperature & Humidity Test Chamber
Environmental simulation chamber for testing materials by simulating conditions at desired temperature and humidity levels
These environmental simulations chambers offer a balanced combination of reliable performance and energy efficiency. Designed for routine testing, it integrates precise temperature and humidity control with thoughtful construction details that help maintain stable conditions and minimize the impact on surrounding areas.

Low-temperature mold testing
Uses: Enables the chamber to create controlled low-temperature and humidity conditions for mold cultivation and evaluation of material resistance to fungal growth.
- The cooling capacity is managed by an electronic expansion valve that improves energy efficiency and keeps power use in check.
- A top exhaust system that helps limit heat buildup in the surrounding workspace.
- Precise temperature and humidity control with minimal fluctuation and a broad operating range to suit diverse testing protocols.
- Standard dual cable ports on each side of the chamber for easy connections when running powered tests.

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.
