The Test Equity Half-cube 105 is a compact environmental test chamber engineered for precise temperature and humidity simulation across a -70°C to +150°C operating range. Designed for component and product validation in space-constrained laboratories, this unit delivers ±0.5°C temperature tolerance and ±3% RH humidity control with minimal footprint. The 1.0 cubic foot chamber maintains ±1.0°C temperature uniformity and supports programmable multi-zone testing protocols via digital controller with RS-232 data logging.
