The Cincinnati Sub-Zero CT-64-6-6-S/RAC is a 64 cubic foot environmental test chamber designed for precise temperature and humidity simulation across extended ranges. This unit delivers temperature control from -70°C to +180°C with ±0.5°C accuracy and humidity control from 10% to 95% RH with ±3% RH accuracy. The cascade refrigeration system achieves cooling rates up to 5°C/minute and heating rates up to 3°C/minute, enabling rapid profile transitions. Built with stainless steel interior construction and high-density polyurethane insulation, the chamber accommodates varied test samples while maintaining strict environmental uniformity. A digital programmable controller enables multi-segment profiling with real-time data logging and out-of-tolerance alarm functions.
