Digital dual-phase voltammetry table clamp SMG2000B

1、 Product Overview

This instrument is a high precision, low price, hand-held, dual channel input measuring instrument designed for field measurement of voltage, current and phase. With this meter, it is very convenient to measure the phase between U-U, I-I and U-I on site, judge the phase sequence of inductive and capacitive circuits and three-phase voltage, detect the connection group of transformer, test the secondary circuit and bus differential protection system, read out the phase relationship between CT groups of differential protection, and check whether the wiring of watt hour meter is correct. Clamp type current transformer is used to input the measured current, so the measured line does not need to be disconnected during measurement. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, so that the short circuit of the line under test caused by the possible wrong wiring is completely avoided, resulting in the burning of the measuring instrument. The display screen adopts a high contrast liquid crystal display, with characters up to 25 mm, and the screen angle can be freely converted to about 70 ° to obtain the best visual effect.

The instrument shell is made of engineering insulating materials and equipped with rubber anti vibration protective sleeve, which is safe and reliable.
