Insulating gloves tester - 70 kVDC

  • Specially developed for dielectric testing of gloves in accordance with standards ASTM D120, ASTM F496 and IEC 60903 (annex E)
  • Leakage current up to 500 μA
  • Can be fully remote controlled from an Android™ device
  • Measures output voltage and leakage current
  • "Pass / Fail" LED indicator
  • Selection of test parameters by glove class with adjustable maximum leakage current
  • Ripple <2%
  • USB and Bluetooth interface
  • Built-in memory


The dielectric tester DT70KV is an instrument specially developed to insulating gloves testing, in accordance with standards ASTM D120, ASTM F496 and IEC 60903 (annex E). It was designed with emphasis on safety, versatility and ease of use. The voltage output is adjustable (according to the glove class), with up to 70 kVDC. Its intuitive interface makes it possible to program the glove class and the maximum leakage current, allowing automatic tests.

Has one LED to indicate the presence of high voltage in the output terminal during a measurement and one bi-color LED to indicate the test result (Pass / Fail).

Meeting the most stringent security requirements, the system is divided into two modules, one for control and the other for high voltage. The high voltage module is equipped with an audible alarm and both modules have emergency stop switch. Through an Android device it’s possible to program all parameters of the hipot, besides remotely controlling the tests, further increasing the security.
