Struggling to diagnose electrical faults without a reliable, accurate metre to hand? The Sealey MM20 Digital Multimeter delivers eight measurement functions in a heavy-duty general-purpose tool built for workshop use. The clear, easy-to-read LCD display makes readings quick to check, while the rugged rubber boot and integral stand keep the metre stable and protected on the bench. A data-hold function lets you freeze readings for easy recording, and the included temperature probe extends measurement to a range of -40°C to 1000°C (±1% accuracy up to 400°C, ±2% over 400°C). AC and DC voltage is covered across ranges up to 600V, DC current up to 10A, and resistance up to 2MΩ. Audible continuity, diode test, and transistor verification mode round out the capability for thorough electrical diagnostics. Supplied complete with a full set of leads and probes, the MM20 is ready to work straight from the box.

A. The MM20 measures AC and DC voltage, DC current, resistance, temperature, audible continuity, and includes a diode and transistor verification mode - eight functions in total.
A. The MM20 measures temperature from -40°C to 1000°C, with accuracy of ±1% up to 400°C and ±2% over 400°C. A temperature probe is included in the supply.
A. For DC voltage, ranges are 200mV (±0.5%), 2V, 20V, 200V (all ±0.8%), and 600V (±0.8%). AC voltage covers 200V and 600V, both at ±2% accuracy.
A. According to the specification, the MM20 does not measure AC current. DC current is measured across four ranges: 2mA, 20mA, 200mA (all ±1-1.2%), and 10A (±2%).
A. Yes. The MM20 features a data-hold function that freezes the displayed reading, making it easier to record measurements without having to watch the display continuously.
A. The MM20 is supplied with a full set of leads and probes and a temperature probe. It is housed in a rugged rubber boot with an integral stand.
A. Yes. The MM20HV is an available variant in the same product family. Please refer to the MM20HV product listing or contact Parts for Machines for confirmation of how the specification differs.
A. Alternative multimeters include the MM01, MM03, MM102, and MM18 - each a different product offering similar diagnostic functionality. Please refer to those individual listings for specification comparisons.
