Puncture / Insulation Tester –LH
Product Introduction


Specially for production line and QC

Testing instrument for electric appliances for industrial safety, necessary for insulation and Hi-Pot testing conditions, R & D, QC, experiment, production, it may be of sole unit, timed, remote control, determination and automatic test and instrument for applying safety standard of any country in the world.



Hi-Pot testing instruments of the Company are specialized in the Hi-Pot testing
of electronic products and electric components and parts that facilitate smooth
pass of CNS, UL, JIS, CE , BE standards

Updated electronic circuit gives accurate and rapid testing moves and tested article will not be damaged during the testing and when the voltage resistance and / or insulation is not qualified, audio and video alarm will be initiated

The unit can determine whether leak current is qualified or not, and performing functional tests of timing and remote control, and on relay output point resetting, disqualified output, and can do automatic tests to reduce labor power and increase efficiency

The unit has high voltage resistance epoxy resin high voltage transformer and high voltage resisting output wires, output KV meter and MΩ meter are high precision hanging wire manufacturing and vibration resistance to ensure the durability and safety of the machine
