Leakage marking tester is a special testing instrument designed and manufactured according to GB4207, IEC60112 and other standards. It is suitable for the measurement of leakage marking index and leakage resistance marking index of electrical and electronic products, solid insulation materials of household appliances and their products simulated under wet conditions. It has the characteristics of simple, accurate, reliable and practical

Leakage marking tester conforms to GB/T4207 test standard. The rectangular platinum electrode was used, and the force of the two poles on the sample was 1.0N respectively. 0.05N. The applied voltage is adjustable between 100 ~ 600V(48 ~ 60Hz), and the short circuit current is 1.0; When 0.1A, the voltage drop should not exceed 10%, when the test circuit, short circuit leakage current is equal to or greater than 0.5A, the time is maintained for 2 seconds, the relay action, cut off the current, indicating that the specimen is unqualified. The time constant of the drop device is adjustable, and the drop amount is accurately controlled by 44 ~ 50 drops /cm3 and the drop time interval is 30

Rectangular platinum electrode was used in the leakage marking tester, and the force of the two poles on the sample was 1.0N±0.05N respectively. The applied voltage is adjustable between 100 ~ 600V (48 ~ 60Hz), when the short-circuit current is 1.0±0.1A, the voltage drop should not exceed 10%, when the short-circuit leakage current is equal to or greater than 0.5A in the test loop, the time is maintained for 2 seconds, the relay operates, cuts off the current, indicating that the specimen is unqualified. The time constant of the dropping device is adjustable, and the drop amount is accurately controlled by 44 ~ 50 drops /cm3 and the drop time interval is 30±5 seconds.
Leakage marking tester conforms to GB/T4207 test standard.
