The Cincinnati Sub-Zero Z32 / ZPH-32-3.5-SCT/AC is a temperature and humidity test chamber engineered for precise environmental simulation across demanding industrial, commercial, and military applications. Built on the Z-Plus platform, this 3.5 cubic feet workspace chamber delivers fast ramp rates, tight control stability, and repeatable performance essential for accelerated stress testing, thermal cycling, and validation protocols. The air-cooled refrigeration system is available with single-stage or cascade architecture, enabling temperature extremes from -70°C to +190°C. Humidity control spans 10% to 98% RH with 40°F (4°C) dewpoint and 185°F (85°C) dry bulb capability.
