1 review for Amprobe AMB-55 Industrial High-Voltage Insulation Tester

  1. Lombard

    Nice unit but unreliable

    I bought this units, the specs are very nice, I love the shielded cables, but after a few months the pushbuttons began to fail, now the unit is not even generating high voltage and warranty just expired, heard that several users have the same problem, avoid this and the 10 KV unit

    ✘ No, I do not recommend this product
