    Drummond MTL20PD Test Lamp and Proving Device

    The Drummond MTL20PD Test Lamp and Proving Device is an ideal solution for anyone who needs to check for voltage in a circuit before starting work. It features a test lamp, proving unit and useful carry case.

    The Drummond MTL20 is a single-pole test lamp that is capable of detecting voltage from 50V to 500V AC and 50V to 750V DC. Voltage presence is indicated by the 360˚ LED display with steps for 50V, 120V, 230V and 400V AC/DC. The lamp is supplied with a straight and right-angled prod which are easily interchangeable.

    The test lamp is capable of drawing a high current by pressing the buttons on the lamp and the probe unit, thus differentiating between phantom voltages and hazardous persistent voltages. It is safety rated as Cat III 1000V and Cat IV 600V.

    The Martindale PD440 Proving Unit produces voltage up to 440V, thus allowing the user to verify the function of the test lamp before checking for voltage presence.

    Both instruments and the test prods are supplied in a handy carry case.
