Benchtop Temperature & Humidity Chamber

Specifications
The DHT® Benchtop Temperature and Humidity Test Chamber (DHTW Series) is engineered with a focus on high-precision environmental control, compact intelligent design, and industrial-grade reliability. Within a limited footprint (0.3–1m³), it delivers a wide temperature range from -70°C to +180°C and precise humidity regulation from 20% to 98% RH. Powered by DHT’s proprietary DHSPLCON™ control system, the chamber ensures exceptional stability, with temperature fluctuations ≤±0.3°C and humidity deviations ≤±1.5% RH.
Its modular stainless-steel inner structure features advanced anti-condensation design, supporting alternating tests and optional rapid temperature change rates up to 5°C/min. The unit is equipped with a high-resolution color touchscreen and IoT capabilities, enabling remote monitoring, program downloads, and USB/Ethernet data export. Multiple safety protections—including compressor overheat safeguard, leakage circuit breaker, and humidity anomaly alarms—ensure reliable unattended operation.
Fully compliant with GB/T 2423.3 and IEC 60068-2-78 standards, the DHTW Series provides a cost-effective and dependable testing solution for laboratory applications in medical electronics, semiconductor packaging, and precision component evaluation.
