Instrument Calibration - Hioki 3455


The HIGH VOLTAGE INSULATION HiTESTER 3455 is made for measuring insulation resistance in high-voltage facilities.

The instrument’s powerful features include the ability to change the settings in fine steps over a wide range of voltages, and an assortment of other functions necessary for a variety of diagnostic requirements. The 3455 is packed in a compact body and offers ease of use. Careful consideration has been made in regards to safety in the design, making the instrument compatible to use almost anywhere.

  • Measure insulation of high-voltage equipment (such as transformers, cables, and motors).
  • Wide testing voltage range, up to 5.00 kV from 250 V DC.
  • Adjustable testing voltage in 25 V steps up to 1 kV, and 100 V steps from 1 kV to 5 kV.
  • Wide measurement insulation range, up to 5 TΩ (at 5 kV testing voltage, 1 TΩ=1012 Ω).
  • Diagnose the insulation of various equipment with the built-in memory for data storage.
