Designed for high accuracy, long-term stability, and flexible test programming, this cabinet provides a controlled environment for electronics, automotive parts, aerospace components, polymer materials, batteries, sensors, and research applications that demand strict thermo-humidity regulation.

With wide thermal capability (–70°C to +150°C), humidity precision of ±2.5%RH, and ±0.5°C temperature uniformity, this alternative humidity and temperature control cabinet provides repeatable conditions for evaluating moisture resistance, corrosion tendencies, dimensional stability, electronic reliability, and hydro-thermal aging behavior. By exposing materials to combined heat and moisture stresses-including swelling, delamination, oxidation, insulation breakdown, and solder fatigue-the cabinet helps engineers identify vulnerabilities and validate performance for R&D, quality screening, and lifecycle assessment.
