Extech VT30 LCD Multifunction Voltage TesterKey Features At A Glance EN61010-1 CAT IV 600V and CAT III 600V safety rating for high-energy electrical environments LCD AC/DC voltage indication at discrete steps: 6V, 12V, 24V, 50V, 230V, 400V, 690V Polarity detection LEDs for positive and negative DC identification Continuity test with audible tone for fast circuit verification Two-handed operation supports low-impedance testing Built-in flashlight illuminates tight or poorly lit test areas Rubberized double-molded IP64 housing — splashproof and dustproof Compact 9.4 x 3 x 1.6 in (240 x 78 x 40 mm) form factor at 8.4 oz (237 g) The Extech VT30 is a handheld digital voltage, continuity, and phase tester featuring a large backlit LCD with bargraph display, designed for electrical verification across AC and DC circuits. The dual-probe tester combines voltage indication, polarity detection, continuity checking, and phase identification in a single rubberized, double-molded instrument intended for everyday electrical work in residential, commercial, and industrial settings.The VT30 covers AC/DC voltage indication at discrete steps of 6V, 12V, 24V, 50V, 230V, 400V, and 690V, with polarity LEDs indicating positive or negative DC. Continuity is verified by an audible tone, and the unit supports two-handed operation for low-impedance testing — useful when distinguishing live conductors from induced or ghost voltages. A built-in flashlight illuminates the test point itself, allowing the user to identify terminals inside panels, junction boxes, or other confined areas without a second light source.Brand HeritageExtech Instruments became part of the FLIR Systems family of brands and now operates under the Teledyne FLIR umbrella following Teledyne Technologies' acquisition of FLIR in 2021. The Extech name and product line have been maintained through these transitions as a recognized brand for handheld electrical and environmental test instruments.Accessories Supplied 2 AAA batteries Protective cap Pouch case Product Core & Specifications Specification Value Display Large backlit LCD with bargraph LCD AC/DC Voltage Indication 6V, 12V, 24V, 50V, 230V, 400V, 690V Polarity Detection LEDs for positive and negative DC Continuity Test Audible tone Operation Two-handed operation for low impedance testing Flashlight Built-in for testing in tight areas Housing Rubberized double-molded IP64 Safety Rating EN61010-1 CAT IV 600V and CAT III 600V Dimensions 9.4 x 3 x 1.6 in.
