MM20 8 Function Digital Multimeter

The Sealey MM20 is an 8-function digital multimeter designed for general-purpose electrical testing and diagnostics across a wide range of trade applications. Built to withstand the demands of workshop and site use, this heavy-duty instrument features a clear 6-digit LCD display with 12mm digits for easy reading in various lighting conditions. Housed in a protective high-impact rubber boot, the MM20 combines durability with practical functionality. The rugged case includes an integral stand for hands-free operation, whilst the data-hold function allows you to freeze readings for convenient recording. This multimeter is ideal for electricians, maintenance engineers and automotive technicians who require reliable measurements of voltage, current, resistance and temperature. The unit measures both AC and DC voltage up to 600V, DC current up to 10A, and resistance up to 2MO with accuracy ratings ranging from ±0.5% to ±2% depending on the range selected. The included temperature probe extends measurement capability from -40°C to 1000°C, making this instrument particularly versatile for HVAC work, appliance testing and engine diagnostics. Additional functions include audible continuity testing for quick circuit verification, plus diode and transistor testing modes for component-level diagnostics. Supplied complete with a full set of test leads and probes, the MM20 arrives ready for immediate use. The low battery indicator ensures you're always aware of power status, and the meter conforms to IEC 1010 safety standards. At just 260g and measuring 140 x 70 x 35mm, this compact multimeter is easily portable between jobs.
