Sealey MM20HV 8 Function Digital Multimeter

The Sealey MM20HV is a heavy duty digital multimeter designed for accurate electrical diagnostics and testing across eight essential functions. Built to withstand the demands of professional use, this general purpose multimeter combines reliable performance with practical features that electricians, engineers and maintenance technicians require on site. Housed in a rugged rubber boot with an integral stand, the MM20HV offers excellent protection against workshop knocks and drops whilst providing hands free operation when needed. The clear, easy to read LCD display features 6 digit readout with 12mm height digits, ensuring measurements are visible even in challenging lighting conditions. A low battery indicator prevents unexpected power loss during critical testing work. This multimeter measures AC and DC voltage up to 600V, DC current up to 10A, and resistance up to 2MO with accuracy ratings from ±0.5% to ±2% depending on the range selected. The integrated temperature probe extends its versatility significantly, measuring from 40°C to 1000°C, making it ideal for HVAC diagnostics, electrical panel monitoring and industrial equipment testing. Additional functions include audible continuity testing for quick circuit verification, plus diode and transistor test modes for component level troubleshooting. The data hold function allows readings to be frozen on screen for recording in awkward locations or confined spaces. Supplied complete with a full set of leads and probes, the MM20HV arrives ready for immediate use and conforms to IEC 1010 safety standards.
