temperature/humidity Test Chambers SDJ40

Independent heating, cooling, humidifying, dehumidifying, special BTHC even and constant adjustment of temperature and humidity guarantees more stable and reliable running of humiture.
Fully-closed imported compressor + environment-friendly refrigerant +mechanical type single-stage/cascade low temperature loop system
Ultra wide humiture range: 20-98% RH, dehumidifying device can be installed to make humidity within 10% RH.
Special air supply ventilation system avoids dead corner of air circulation in the chamber and improves evenness of humiture of products.
Perfect security protection device guarantees more safe and reliable running of products.
Various stable and reliable humiture controllers with mature technology are convenient for users to select according to their needs.
