Megger MIT320-EN Insulation Tester, 1000 Megaohms Resistance, 250V, 500V, 1000V Test Voltage

The Megger MIT300 series insulation resistance tester measures insulation resistance, voltage, and continuity in electrical installations, building maintenance, and electrical testing. The average-sensing meter provides accurate readings when measuring linear loads, where the current or voltage has a sinusoidal waveform. The dual LCD screen indicates test results either digitally or with an analog arc function to replicate the response of analog meters. The tester measures insulation resistance from 0 to 1,000 megohms, voltage from 0 to 600V, and continuity from 0.01 to 100 ohms. The unit has a test inhibit function that prevents testing on circuits carrying over 50V. The tester is safety rated to European Standard EN61010-1, Category III, 600V. The unit is also Ingress Protection 54 (IP54)-rated for protection against dust and splashing water. The unit has a rubberized outer case for protection against bumps and short drops. The Megger MIT300 series is commonly used by electricians and electrical contractors.

Specifications

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. Available in handheld or benchtop form, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit, and multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form using digits or a graphic representation on an LED screen. Meters have electrical properties that are to be measured and the anticipated range of results, and should have a rating that is higher than the maximum value of the anticipated range. An electrical test meter has multiple settings corresponding to potential ranges of values for the properties it can measure. A manual ranging meter requires the operator to flip through different settings until the correct range is reached. An autoranging meter cycles through range settings automatically until it reaches the correct range.

Megger manufactures equipment for cable fault locating, protective relay testing, telecommunications and data integrity, and power quality testing under multiple brand names, among them Megger, Biddle, States, and AVO. The company, founded in 1889, is headquartered in Dover, England, and meets International Organization for Standardization (ISO) 9001:2008 standards.
