MEWOI1000A Bluetooth Version H/L voltage Clamp Current Meter is designed and manufactured for measuring high voltage current below 110KV, high altitude current (need to install insulating rod) and low voltage current. The instrument adopts precision CT technology and mask digital integration technology. The instrument is composed of a special clamp ammeter , Bluetooth APP and insulating rods, when testing high-voltage lines above 600V, insulating rods must be installed. The clamp head guide area of the clamp meter adopts an innovative integrated design, and the clamp head iron core is made of permalloy material, which can test the leakage current. The instrument has Bluetooth function. After downloading the APP on the mobile phone, the test can be performed and the test data can be viewed in real time.

      MEWOI1000A Bluetooth Version H/L Voltage Clamp Current Meter has the functions of peak value hold, data hold, data storage, bluetooth and so on. High precision, high reliability and high stability of uninterrupted testing throughout the year. Widely used in substations, power plants, industrial and mining enterprises, testing stations, electrical maintenance departments for current detection and field electrical work. It can also be used for high and low voltage transformation ratio testing, that is, to measure the high and low voltage currents of the primary circuit and the secondary circuit respectively, and then calculate the high and low voltage transformation ratio. The insulation rod is light and has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance and high insulation.
