Product overview
Photovoltaic Module Cyclic Salt Spray Chamber HD-E808-4C is an environmental test chamber designed to assess corrosion resistance and accelerate aging of photovoltaic (PV) modules under cyclic marine conditions (salt spray, drying, high temperature/high humidity). It reproduces cyclic corrosion mechanisms to evaluate long-term reliability.

Test standards

• IEC 61701:2020 (according IEC 60068-2-52:2027)
• ASTM G85
• ASTM B117

Application and sample capacity
Suitable for testing PV modules up to 2400×1200 mm; chamber holds two 2400×1200 mm modules simultaneously. Lab volume: 4540 L (excluding sloping roof capacity).
