Electronic component aging tests, material weathering tests and pharmaceutical stability studies all need equipment that holds temperature and humidity precisely for long periods. The JHHWS-260BE has a 260 L working volume, 0–70 °C range with ±0.1 °C control precision and 30–98% RH humidity. Its 8K mirror stainless steel liner resists corrosion and cleans easily; the unit weighs about 100 kg and moves on casters. A 24-segment programmable controller supports time-segmented settings, and ultrasonic humidification works with condensing dehumidification for steady humidity control. Multiple safety protections (over-temperature cutoff, compressor overpressure, sensor fault alarm) support long unattended running.
