High and Low Temperature Humidity Chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2), IEC60068-2-78, IEC60598-1, GB/T2423.17, GB/T5170.2, GB/T5170.5. It is used to test the CFL/LED which meets IES LM-80-08, electricity products, electronic components, material and so on.

Specifications:
•The chamber is made of SUS304 Steel. The thermal insulation layer is made of polyurethane hard foam ultra-fine glass fiber. The heat-insulated doorframe uses high temperature aging silicone rubber sealing strip.
•The temperature controller includes Korean TEMI display in English/Chinese and German Siemens PLC. It can communicate with PC via RS-232. The temperature accuracy is 0.1℃ and humidity accuracy is 0.1%R.H
•The temperature sensor is platinum PT100Ω/MV
•The independant heating system uses nickel-chrome electric heater
•The refrigerating system is fully enclosed air-cooled single-stage compression refrigeration mode, and the compressor is from France TECUMSEH brand which can allow you get after sales support from many other countries
•The circulation system uses temperature resistant and low noise air-conditioned motor and multi-blade centrifugal wind wheel
•The safety protection system includes electric leakage, short circuit, over temperature, motor overheating, compressor pressure, overload, over-current protection
•Working Voltage: AC380V±10% 3phases and frequency 50Hz/60Hz
•Working Environmental: Temperature is 5℃～+30℃  Humidity ≤85%R.H

 The * in GDJS-225*/GDJW-225* means the temperature range A: -20℃-150℃, B: -40℃-150℃,  C: -60℃-150℃，D: -70℃-150℃
