Drummond Test Lamp MTL20

Bright LED indication of voltage between 50V and 500V AC/DC

Four distinct bands of illumination above 50, 100, 200 and 400V AC/DC with a 360o viewing angle even in bright sunlight

Identifies potentially lethal voltages at 50V and distinguishes between 110V, 230V and phase to phase voltages in 3 phase systems

Additional two button test allows the unit to draw a high current to differentiate between potentially hazardous phantom voltages and hazardous persistent voltages

Finger shields and insulated probe tips with only 4mm of exposed metal

Double insulated cable with white inner insulation gives a clear warning of abrasion and is heat and oil resistant

Meets the UK Health and Safety Executive guidance notes on electrician’s test lamp (GS38)

Complies with BS EN 61243-3 and BS EN 61010. CAT IV 600V, CAT III 1000V

No batteries required

Mains Voltage Indicators - Contact

Caution

Test lamps should be proved safe before and after use, by testing on a known live circuit, using the continuity tester, or through the Martindale PD690 proving unit.

Supplied with

Right angled probe tip, two straight tips and instructions
