Safe and Time Saving

Traditional phase sequence measurement methods must poke the three-phase wire terminal, and connect the three bare alligator clips or test pins of phase sequence meters to the three bare firing lines, while MEWOI2000E uses clamp non-contact measurement, without taking off the wire and no need to contact high-voltage bare fire-wire, the test can be made by directly clamping the three-phase insulating sheath by three super-sensitive high-insulated clamps. Conducting measurement on sheathed cable significantly improves the safety of field testing, effectively protect the operator’s personal safety and increase productivity!

Convenient Operation

Instrument base plate is provided with magnet, instrument can adsorbed on the metal shell when testing, the operation more convenient.


In addition to phase sequence detection, it also has the functions of live wire examination, simple power detection, fire-wire identification, phase deficiency determination, break location detection, DC line break and line maintenance, equivalent to 3 induction electric pens. 

Dynamic Display

LED dynamic display, intuitive and clear

Sensitive and reliable

More sensitive MEWOI2000E clamp, can even sense the AC voltage signal as low as a few Volts, with a wider range of live electricity.

Beautiful and scientific

The three clamps of MEWOI2000E are in three colors, Red, Yellow and Green; It is more in line with the distinction of three-phase line, and more scientific and artistic overall appearance.

Ultra-low Power Consumption

MEWOI2000E has a better power-saving performance with the maximum rated power of 100mVA.
