Temperature Test Chamber

Temperature Test Chamber

The MHW-25-S Constant Temperature Test Chamber (25L) is a compact, high-precision solution designed for small pouch cells and coin cell temperature testing. With an internal volume of 25L and an inner size of W280 × D250 × H360 mm, it delivers stable and uniform conditions in a small footprint, ideal for labs with limited space. Operating in the 0℃ to 60℃ range, the chamber ensures excellent stability with temperature fluctuation ≤1℃ and temperature deviation ±2.0℃ (no load, stable state).

Built with a stainless steel SUS304 inner chamber and a cold-rolled steel outer body with sprayed finish, it offers durability and corrosion resistance. The 50 mm polyurethane foam insulation enhances thermal efficiency, maintaining consistent conditions while reducing energy loss. Heating from 25℃ to 60℃ within 30 minutes and cooling from 25℃ to 0℃ within 50 minutes, it provides rapid temperature transitions for efficient test cycles. Combined with an axial flow fan, evaporator and heater, the MHW-25-S ensures uniform airflow, making it a reliable choice for battery R&D labs focused on safety, repeatability, and controlled temperature testing. Note: the chamber is not suitable for flammable, explosive, corrosive, radioactive, highly toxic, or strong electromagnetic emission samples.
