98x Teraohmmeter/Insulation Resistance (IR) Tester

The 98x Series Teraohmmeter meets today’s demanding requirements for higher voltage IR (insulation resistance) testing.

In a never ending race for higher efficiency, electric vehicles and solar panel arrays are now operating with voltage rails up to 2.5 KV.  This is no place for a 1 KV tester, it’ time to step up to a Vitrek 98x!

Built upon the same DSP technology that has established Vitrek as a leader in hipot test systems, the 98xi devices feature a unique combination of performance features including:

  • Multi-dwell Functionality (multiple steps without having to return to zero between steps)
  • High-speed Testing (with dwell times as low as 100 ms)
  • Pico-Amp Leakage Measurement (with stable and precise 50 Teraohm IR readings)
  • Continuously Variable IR Test Voltage (adjustable over the full output range of the instrument)
  • Multi-mode Insulation Resistance Tests (three test modes – end on time, end on pass, end on fail)
  • Capacitance Test Modes (critical for solar panels, cable harnesses and other capacitive loads)

For applications requiring insulation resistance tests of multiple conductors, the Vitrek 98×1 IR Testers have the capability of directly controlling up to four 64-channel Vitrek 964i high-voltage scanners. Utilizing a PC equipped with Vitrek’s QT Enterprise™ software, the same instrument can handle up to 1020 test points.
