  • 6.5KV Teraohmmeter/IR Tester
  • 98x series teraohmmeter / insulation resistance tester
  • 11 KV DC output voltage
  • Meets today's demanding requirements for higher voltage IR testing
  • Ideal for higher voltage IR requirements, such as electric vehicle systems and higher voltage solar arrays
  • Based on Vitrek's proven DSP technology
  • Can directly control up to four 64 channel HV scanners, right out of the box
  • Has a unique combination of performance features - multi dwell functionality, high speed testing, pico-amp leakage measurement, continuously variable IR test voltage, and more

The new 981i and 983i Teraohmmeters are designed to tackle the toughest High Resistance measurement applications. Demanding applications that most other IR testers won't measure up to. So when it's time to test higher voltage IR values like today's electric vehicle systems and higher voltage solar arrays - look to Vitrek to deliver the IR tester you need for your production line.

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 IR (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)


  • 6.5KV Teraohmmeter/IR Tester
  • Alligator test leads
  • NIST traceable calibration certificate with no data
  • Power cord
  • Operator's manual


  • Dimensions (H x W x L): 431.8 mm × 457.2 mm × 101.6 mm (17 in × 18 in × 4 in)
