The Drummond MTL20 test lamp safe voltage indication from 50 - 500V AC / DC. In addition to the 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.

A unique feature of this 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
