ETCR1800B Wireless High Voltage Electroscope (With voltage and current indication) is specially well-designed and manufactured for high voltage transmission line electricity testing, high voltage transmission line voltage to earth testing, induction voltage testing and current testing., The product breaks through the traditional high voltage electroscope limitation just can only check whether there is electricity, this instrument can test the high voltage to the ground voltage while  electricity testing and  alarm, the B type can also test the high voltage line current. ETCR1800 series Wireless High Voltage Electroscope electricity testing voltage level380V～220kV, completely covers the electricity testing and ground voltage test of each voltage level(380V、6.6kV、10kV、35kV、66kV、110kV、220kV), no need to purchase multiple sets of high voltage electroscope according to different voltage levels, which can save cost, safety, reliability and save time. It is a necessary tool for power transmission line maintenance. In the maintenance and repair of the transmission line, even if the line has been disconnected, due to the capacitive effect, there may still exist very high high-voltage through with induction, which seriously threatens the safety of the operators and operation process. It is necessary to pass the electroscope to check whether the voltage of the cable has been reduced to a safe and operable voltage level. ETCR1800B wireless high voltage electroscope also has the function of testing the current of high-voltage line, which is the first high-voltage electroscope with the function of voltage test and current test in China. It provides a safe, practical and convenient new electric instrument for electricity inspectors.

ETCR1800B Wireless High Voltage Electroscope consists of host receiver, detector, telescopic insulation rod, monitoring software and USB communication cable etc. During the test, you only need to hang the detector on the bare wire with insulation rod, the voltage value can be read on the handheld receiver through by wireless signal transmission. The wireless signal transmission straight-line distance is about 30 meters. The detector has red LED and buzzer and other sound and light alarms, making the test easier and convenient. 

Monitoring software has online real-time monitoring, historical data query, save, print and other functions.
