Product introduction

SMG20000E Digital Display Clamp-on Phase Meter is special designed for voltage, current and phase tests, it is in high-precision, low price, portable hand-held, dual-channel input measuring. It's easy to measure the phase between U-U, I-I and U-I, identify the inductive circuit ,capacitive circuit and the phase sequence of three-phase voltage, detect the wiring group of transformer, test the secondary circuit and bus differential protection system, display the phase relationship among the CT groups of a differential protection system, and check if the wire of electric meter was correctly connected. When testing customers do not need cut off the tested current which input by clamp-current transformer. When measuring the phase between U1 and U2, the two input circuit loop are completely isolated, so the possible misconnection is absolutely avoided, which may result in short circuit and may even burn the meter. The monitor of the device is high-contrast LCD screen, and the character in big size, which helps to obtain the best visual effects.

Alternative name

Phase meters, double clamp phase meter, two-phase voltammetry table clamp, clamp phase meter, clamp phase voltammetry table, digital dual clamp phase meter, digital dual clamp phase meter, low voltammetry phase detection table, handheld digital dual phase voltammetry table clamp, double clamp digital phase meter, double clamp digital phase meter

The Characteristics of the products
