Metrel MI 3201 TERAOHM 5 KV PLUS

MI 3201 TeraOhm 5 kV insulation tester is a portable instrument intended to measure insulation resistance through the use of high voltage DC test voltages up to 5 kV. The large LCD screen allows real-time R(t) graphs to be displayed


  • Automated testing – PI, DD, DAR calculations with automated resistance ranging (AR). All data is displayed during one single measurement.
  • Fault finding – Fully programmable step voltage and withstanding voltage test functions to assist in diagnosing faults in insulation.
  • R(t) graph – Real time resistance against time graph plotting facility to graphically illustrate the response of a material to an applied test voltage.
  • Faster testing – High 5 mA charging current quickly charges capacitive loads.
  • Accurate – Selectable noise rejection filters (up to 5 mA) and shielded cables as standard ensure accurate readings.
  • Safe – High CAT IV, 600 V voltage protection
  • Portable – Lightweight 3 kg design with carry handle and shoulder strap
