DHT - Thermal & Moisture Resistance Tester
The DHT Thermal & Moisture Resistance Tester is engineered for precise control over environmental conditions, essential for evaluating the effects of temperature and humidity on various materials. It operates between -70°C to +180°C and 20% to 98% relative humidity, ensuring conformity with standards such as GB/T 2423.3-2006 and IEC 60068-2-30/78. The tester achieves temperature uniformity within ±1.0°C and humidity accuracy within ±3.0% RH, vital for assessing materials under thermal stress and humid conditions, including insulation and corrosion effect testing. The chamber incorporates an optimized airflow system for even thermal distribution, accommodating high-density testing loads like PCB and battery modules. Constructed with a stainless steel interior and a multi-stage filtration system, it maintains test environment integrity over prolonged periods. Compliance options for 21 CFR Part 11 and robust safety features ensure it meets the rigorous demands of automotive, aerospace, and defense sectors.
The DHT® Thermal & Moisture Resistance Tester leverages DHSPLCON intelligent control technology to deliver precise temperature and humidity regulation, covering a wide operating range from -70°C to +180°C and 20% to 98% RH. It ensures temperature uniformity within ±1.0°C and humidity deviation within ±3.0% RH, fully meeting the testing requirements of GB/T 2423.3-2006 (Damp Heat, Steady State), GB/T 2423.4-2008 (Damp Heat, Cyclic), and IEC 60068-2-30/78 for evaluating material degradation, insulation performance loss, and corrosion effects under humid thermal conditions.
Engineered with an optimized airflow architecture and full cross-sectional horizontal turbulence circulation, the chamber ensures uniform thermal distribution even under high-density loads such as PCB assemblies and battery modules. The 304 stainless steel interior and four-stage chemical filtration system effectively suppress background contamination, enabling long-duration stability tests such as 96-hour saturated humidity cycles.
Additionally, the system supports real-time data traceability (21 CFR Part 11 compliance optional) and features comprehensive multi-level protection including over-temperature, short-circuit, and compressor overload safeguards. The DHT® chamber is widely adopted for sealing validation of electric drive systems in new energy vehicles, humid-thermal cycle evaluation of spacecraft thermal control materials, and environmental adaptability certification of military-grade electronic equipment.
