Project Description


HT9910 Hipo tester
  • The withstanding voltage test (also called dielectric strength test, hipot test, hi-pot test, breakdown test or flash test) is made to stress the device under test to an AC or DC high voltage and check that there is no breakdown nor perforation happening.
  • HT99xx hipot tester includes 3 models of HT9910/9912/9922.
  • Each model combines AC/DC withstanding test and insulation resistance (IR) function tests.
  • With optional RS485 interface and MODBUS protocol,HT99XX series Hipot Tester can be easily realized instrument network.


  • AC/DC/IR 3 in 1 hipot tester (HT9922 only)
  • AC/DC voltage output to 5kV and 6kV
  • Insulation resistance test from 100KΩ ~ 100GΩ
  • With ARC detection and over power detection
  • 6 test modes available can be programmed to realize automatic and continuous testing.
  • Various interface configuration suitable for automated test system


  • Automated test systems
  • Household appliances
  • Transformers
  • Motors
  • Electrical equipment
  • Heating appliances
  • Photovoltaic industry
  • New energy vehicles
  • Electronic components
  • Medical equipmen
