Click to download: Selection Map
| MEWOI168BE Clamp on AC/DC current Sensor is designed for testing AC/DC current with voltage under 600V on-line. Adopt the latest CT technology and digital integrated technology. There is not any metallic conductor outside the clamps, non-contact test to ensure save. It is small in size; high accuracy can connect with multi-meter, oscilloscope, electric power quality analyzer, etc. Widely applied in electricity, communication, meteorology, railway, oilfield, construction, measurement, scientific and research teaching unit, industrial and mining enterprises. |
