It applied with rectangle size of platinum electrode, each electrode can force to the sample is 1.0±0.05N       

Electrode Distance: 4.0mm±0.01mm, included angle: 60°±5°

Electrode Voltage: 100~600V, (48~60HZ) adjustable, when the short-circuit current at 1.0±0.1A, the voltage goes down less than 10%

The liquid drop device can make the liquid height from 30~40mm (adjustable), drops liquid size is 44~55 drops/1cm3. The interval drops of liquid is 30s±5s (adjustable)

During the testing, the short-circuit current is more than 0.5A to keep 2 seconds, then shut off current, it show the sample not pass.  Inside dimension: 0.5CBM and outside dimension: 630mm*390mm*750mm
