Megger MET1000 True RMS Electrical Tester
Built for electricians and electrical engineers, the Megger MET1000 True RMS Electrical Tester combines voltage, current, resistance and continuity functions in a robust handheld instrument with detachable test leads. LED and 10,000-count LCD displays show measurement information, while the built-in clamp measures AC current up to 200 A. Auto-ranging voltage testing reaches 999.9 V AC or DC, and the instrument carries CAT IV 600 V and CAT III 1000 V ratings within an IP65 housing.
True RMS measurement applies to AC voltage and AC current, supported by phase rotation and single-pole phase checks for additional electrical testing tasks. Voltage can still be measured without batteries within the stated operating limits, while data hold, a self-diagnostic check and automatic power control support routine use. A bright LED torch assists in poorly lit conditions, and the protective finger guard, carrying holster and rear probe mounting help protect the user and instrument during work and transport.
Key Benefits
- Combines auto-ranging voltage, continuity, resistance and AC current measurement in one handheld tester
- True RMS measurement supports AC voltage and AC current testing
- Detachable test probes and a built-in clamp support different measurement methods
