Supplier: Elf Electronics Pty Ltd playlist_addCompare

The Elf Electronics, HV INSULATOR TESTER has been developed as a field useable insulator testing instrument.

Price Guide (Inc GST): POA

The HV HV INSULATOR TESTER will measure the voltage across an insulator in a live line insulator string, to enable speedy and accurate identification and replacement of faulty insulators.

The large 25mm high display allow easy and safe readings to be made.

The construction is rugged for field use and when not in use a strong ABS moulded case protects the tester against transport vibration.


Any task requiring staff to come into close proximity of high voltages should be classed as a risk, and therefore should only be undertaken by properly trained and skilled persons

The HV INSULATOR TESTER is to be used only for the purpose specified and in the manner specified in these operation instructions. Use of the unit for other purposes and not in accordance with these instructions may result in electric shock causing serious injury or death.
