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.
