The main performance of equipment:
Water jacket (UL 1703 test condition, option)
Double-deck Layer P.P., Good performance of insulation
Automatic water supply, water shortage can automatically supplement.
Double door, ensure the water and gas no leakage.
Precision glass nozzle, mist diffusion uniform.
Double over-temperature protection, water level warning, ensure safe use.
Temperature control precision: 0.5°C ( resolution 0.1°C )
Heating, humidification, gas delivery system, from the outside to the inside.
Compressed air fast exclusion of mist after test.
The PLC programmable control, English operation interface.
Test subject and pass criteria:
① UL 1703-2008:
after the test, the corrosion products formed on the test sample shall not be more than that formed on the reference sample as determined by visual observation. Corrosion in the scribed line area is judged by the spread of corrosion from the scribed line.
② IEC 61701 Ed.2:
Visual inspection, Maximum power determination, Insulation test, Bypass diode thermal test, Wet leakage current test, Ground continuity test.
