Product Introduction

ETCR EM9310B Large Caliber U-shaped Wireless H/L Current Meter, also known as U-shaped H/L Clamp Current Meter, overhead line load tester, high voltage load tester, high altitude current tester, high voltage current telemeter, which is used for measurement of H/L AC current of overhead line below 110kV. The unique U-shaped opening structure realizes unhindered measurement, and on-site testing is particularly convenient. It is widely used in substation, power plant, industrial and mining enterprise, testing station, electrician maintenance department for current detection and field electrician operation,etc.

ETCR EM9310B Large Caliber U-shaped Wireless H/L Current Meter is composed of u-shaped clamp jaw, receiver and insulating rod. Testing below 110kV requires insulating rod (testing below 500kV can be customized), no request insulating rod when measure below 600V. The meter has data hold, memory function, etc.

1.Unique U-shaped opening structure realizes unhindered measurement, and on-site testing is particularly convenient.

2.Testing below 110kV requires insulating rod (testing below 500kV can be customized).
3.Ultra-wide current range: 0.00A~9999A.
4.Adopt with wireless transmission method, transmission distance 100m.
5.Memory: data storage 99 groups.
