About the ETSP-TH Series Environmental Chamber
The ETSP-TH series from ETSP, South Korea, are climatic chambers with temperature and humidity control, for testing the durability or operating status of parts and products in extreme conditions as defined in IEC 60068-3-5:2001, IEC 60068-3-6:2001, MIL-STD-810G and NATO STANAG 4370. The series addresses noise, poor humidity control and condensation, slow temperature and humidity variations, and unbalanced air distribution inside the chamber.
The temperature range is -40 °C to +150 °C with a single-stage refrigeration system, or -70 °C to +150 °C with a cascade refrigeration system, with accuracy of less than ±0.3 °C. The humidity range is 10% to 95% RH with stability of less than ±1.5% RH, and automatic, precise water level control maintains accurate control of relative humidity and temperature.
Eight models, ETSP-TH 150 to ETSP-TH 1800, offer useful capacity from 150 to 1,800 litres, and custom-designed chambers are available on demand. The ETSP-TH series is manufactured according to Total Quality procedures, in compliance with the ISO 9001 standard.
