Sealey MM01 Auto Ranging Digital Multimeter

The Sealey MM01 is an auto-ranging digital multimeter designed to simplify electrical testing for electricians and contractors. This intelligent meter automatically detects and selects the required test function, eliminating the need for manual range selection when measuring AC/DC voltage and current, resistance, and continuity.

With 4000 count high precision measurements and accuracy ratings up to ±1% on DC voltage readings, the MM01 delivers reliable results across multiple voltage ranges up to 600V. The non-contact voltage detection (NCVD) feature enables safe one-handed operation when checking for live circuits, whilst the integrated LED worklight illuminates work areas in dimly lit environments such as consumer units or underfloor installations.

Practical features include data-hold for capturing readings, auto-power-off to preserve battery life, and a low battery indicator. The hi-impact rubber case protects the meter on site, whilst the easy-to-read LCD display with 16mm digit height ensures clear visibility. Supplied with 2 x 1.5V AAA batteries, this meter is ready for immediate use.

The MM01 conforms to EN 61010-2 CATIII 600V safety requirements, making it suitable for testing electrical installations, troubleshooting circuits, and general electrical maintenance work where compliance with recognised safety standards is essential.
