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 MEWOI2000D 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!
|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.
|LED dynamic display, intuitive and clear
Sensitive and reliable
|More sensitive MEWOI2000D 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 MEWOI2000D 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.
