Description
Overview:
The Sealey Digital Multimeter 8 Function with Thermocouple, Part No. MM20, is a handheld electrical measuring instrument for workshop, site, and garage use. It combines AC and DC voltage, DC current, and resistance measurement in one unit, with additional checks for continuity, diodes, and basic transistor verification. A clear LCD display makes readings easy to see, while a protective rubber boot with an integral stand helps resist knocks and allows stable bench use. Supplied with standard test leads and a thermocouple temperature probe, it can take contact temperature readings alongside electrical tests. It is suitable for maintaining and fault-finding on power tools, small plant, garden machinery, generators, chargers, and vehicles. Model names used: Sealey MM20 and Digital Multimeter 8 Function with Thermocouple.
Key Features:
- 8-function instrument: AC/DC voltage, DC current, resistance, continuity buzzer, diode check, transistor verification, temperature, and data-hold
- Thermocouple temperature probe included for contact thermal readings alongside electrical tests
- Data-hold function freezes the display to capture and record results
- Audible continuity testing for quick wiring and fuse checks without looking away
- Durable rubber boot with integral stand for protection and hands-on or hands-free use
- Clear LCD with easy-to-read digits for reliable visibility on site or at the bench
- Supplied ready to use with test leads, probes, and temperature sensor
- Compact, lightweight form factor that fits easily in a tool bag or service pouch
- Suitable for basic component verification, including diodes and simple transistor testing modes
- Battery powered for convenient use in the field without mains power
Typical Applications:
Electrical diagnosis and maintenance on small plant, garden machinery, workshop tools, and vehicles; checking battery and charging circuits; tracing shorts and open circuits in cables and switches; verifying fuses, connectors, and earths; measuring resistance of sensors and heating elements; and taking surface or contact temperature readings on components, housings, and cooling systems during fault-finding or routine servicing.
Also known as:
VOM, DVM, multi-tester, continuity checker, voltage/resistance tester, diagnostic tester for electrical circuits, temperature tester with thermocouple, general-purpose test meter for maintenance and troubleshooting.
