Multi Testers: Measure with Precision, Work with Confidence

Diagnose, test, and measure every electrical parameter with absolute accuracy using our comprehensive Multi Tester lineup — the essential toolkit for electricians, HVAC technicians, maintenance engineers, and industrial professionals who cannot afford to guess. Our collection spans the full range of electrical measurement instruments: digital multimeters for measuring AC and DC voltage up to 600V, current, resistance, continuity, diode and transistor testing with non-contact voltage detection built in; digital clamp meters that combine full multimeter capability with jaw-style AC and DC current measurement up to 1,000 amperes without breaking the circuit; fork testers for fast live-wire current checks on conductors too tight for standard clamp jaws; single-pole phase testers certified to international safety standards for quick live-wire identification; insulation resistance testers operating at 500V and 1,000V test voltages for verifying wiring integrity up to 2,000 MΩ in residential and co
