Sealey MM20 8 Function Digital Multimeter

The Sealey MM20 is an 8-function digital multimeter designed for general-purpose electrical testing and diagnostics across a... morewide 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. Features and Benefits: • Eight measurement functions cover voltage, current, resistance, temperature, continuity and component testing • High-impact rubber boot protects against workshop knocks and drops • Data-hold function freezes readings for convenient recording • Temperature probe included for measurements from -40°C to 1000°C • Integral stand enables hands-free operation • Clear 6-digit LCD display with 12mm digits for excellent readability • Complete with test leads and probes for immediate use Specifications: Brand: Sealey Nett Weight: 260g AC Voltage (Accuracy): 200V, 600V (±2%) DC Voltage (Accuracy): 200mV (±0.5%), 2V (±0.8%), 20V (±0.8%), 200V (±0.8%), 600V (±0.8%) AC Current (Accuracy): No DC Current (Accuracy): 2mA (±1%), 20mA (±1%), 200mA (±1.2%), 10A (±2%) Resistance (Accuracy): 200O, 2kO, 20kO, 200kO (±0.8%), 2MO (±1.2%) Capacitance (Accuracy): No Temperature (Accuracy): Range; -40°C-1000°C, (±1% up to 400°C), (±2% over 400°C) Frequency (Accuracy): No Duty Cycle: No Continuity Audible: Yes Diode Test: Yes Transistor Test: Yes High-Impact Rubber Case: Yes Digits x Height: 6 x 12mm Low Battery Indicator: Yes Battery (Supplied): 1 x 9V Information: Integral Stand Size (L x W x D): 140 x 70 x 35mm Weight: 260g Conformity: IEC 1010
