Test Lamps

The Martindale Drummond MTL10 & MTL20 test lamps safe voltage indication from 50 – 500V AC / DC and and 50V to 750V DC forming part of the Martindale electrical test equipment product portfolio.

In addition to the Martindale Drummond MTL10, the new model MTL20 incorporates two test buttons, one on the body of the unit and one on the probe. Simultaneous depression of both buttons enables the unit to draw a high current, allowing the user to differentiate between phantom voltages and hazardous persistent voltages.

The robust design meets the recommendations of the Health and Safety Executive in their guidance notes on the electrician’s test lamp (GS38) as well as complying with BS EN 61243-3 and BS EN 61010, CAT III 1000V and CAT IV 600V.

A unique feature of this new Drummond test lamp are the four distinctive bands of illumination, with a 360° viewing angle, providing indication of voltages above 50, 100, 200 & 400 volts, even in bright sunlight. This allows for accurate identification of potentially lethal voltages at 50V and enables the user to distinguish between 110V, 230V and phase to phase voltages in a 3 phase system.

Both the lamp housing and the probe have a finger shield and insulated probe tip with only 4mm of exposed metal. A two layer double insulated cable with white inner insulation gives a clear warning of abrasion that might compromise the user’s safety, and is resistant against heat and oil. To enable use in most circumstances, a right angled probe tip is supplied in addition to the two straight tips. For maximum ease of use the right angled probes can be rotated through 90, 180 and 270 degrees.
