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. |
Multi-Purpose | 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. |
