ETCR EM9100B Wireless H/L Voltage Clamp Current Meter , also known as overhead line load tester, high voltage load tester, high altitude current tester, high voltage current telemeter, which is used for measurement of H/L voltage of overhead line. The meter is composed of dedicated clamp type current meter and high voltage insulation rod. If do not use an insulating rod, it can also be used as high-precision low-voltage clamp ammeter. 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 EM9100B Wireless H/L Voltage Clamp Current Meter is composed of clamp jaw, receiver and insulating rod, the wireless communication distance between the clamp jaw  and receiver is 30m. The innovative integrated design of clamp jaw and guidance zone can quickly and easily clamp or remove the tested wire by pressing or pulling the insulating rod, which is safe and fast.The meter also has functions such as data hold, and memory, etc.

1.Suitable for line voltage below 60kV, the insulated rod should be required when measure above 600V.
2.Innovative automatic plug-in/out structure, clamp or remove the tested wire by pressing or pulling the insulating rod, which is safe, efficient and fast.
3.Can be used to measure leakage current.
4.Wireless communication distance: 30m
5.Memory: data storage 99 groups.
