High/Low Temperature Constant Humidity Test Chamber (49 L,-70 °C)

This product is a high and low temperature constant humidity test chamber designed for the rigorous environmental testing of battery cells and related materials under controlled thermal and moisture conditions. With a 49-liter working volume and a low temperature capability down to -70°C, it enables reliable simulation of extreme climatic stresses, essential for evaluating the performance, safety, and durability of lithium-ion, solid-state, metal lithium, and other advanced battery chemistries. The chamber supports precise humidity regulation alongside programmable temperature cycling, making it suitable for standard test protocols such as charge/discharge stability, thermal shock resistance, and aging studies. Its compact footprint and robust refrigeration system facilitate integration into research labs for R&D of prismatic, cylindrical, pouch, and stacked battery assemblies. The unit’s wide temperature range and uniform conditioning are particularly relevant for characterizing electrochemical stability under cold and damp-heat conditions, supporting both material development and quality assurance in battery manufacturing lines.
