The Major Tech Digital Insulation Tester is a professional-grade insulation resistance meter designed for electrical contractors, technicians, and facilities managers. It features three voltage ranges (250V, 500V, 1000V) with multiple insulation resistance scales up to 2000MΩ, continuity testing, and a 1mA output for safe, accurate measurements on live and de-energised circuits. The IP54-rated casing, backlit display, bargraph readout, and CAT II 1000V / CAT III 600V safety certification make it ideal for field installation testing, maintenance diagnostics, and compliance verification on distribution boards and electrical installations.
