The Cincinnati Sub-Zero ZPS-32-2-SC/AC is a 32 cubic foot environmental test chamber engineered for precise temperature and humidity control across demanding test scenarios. This unit simulates extreme environmental conditions from -70°C to +180°C and humidity levels from 10% RH to 95% RH, making it ideal for validation testing in quality control, R&D, and production environments. The cascade refrigeration system, electrical heating, and steam-based humidification deliver ±0.5°C temperature accuracy and ±3.0% RH humidity control. A digital programmable controller with LED/LCD display supports multi-segment profiles including ramps, soaks, and holds, while data logging and standard communication ports enable real-time monitoring and test documentation. Stainless steel construction throughout ensures durability in corrosive test environments.
