Guangdong ETCR Electronic Technology CO.,Ltd. recently released a new product, the ETCR1810 AC/DC Voltage Tester, designed for measuring and alarming the ground voltage of high and low voltage power lines as well as railway contact network lines. The voltage measurement range can reach up to 1500V. The instrument features a telescopic rod structure with a retractable length of 1600mm and an extended length of 5000mm. During power line maintenance, adjacent operational lines may generate induced voltage due to capacitance effects, posing a serious threat to the safety of maintenance testing instruments and operation personnel. This instrument enables rapid measurement of the voltage during power transmission line operation or the induced voltage during maintenance, thus protecting equipment and personnel safety.
ETCR1810 AC/DC Voltage Tester is equipped with sound and light alarm functions. When the line voltage exceeds the safety voltage value, it emits sound and light alarms to remind operators to pay attention to safety. With its convenient portability and simple operation, the instrument provides electric inspectors with a safe, practical, and convenient new type of power measurement instrument.
Product Features:
1.Easy operation with retractable pole structure, ensuring safety and reliability.
2.Equipped with sound and light alarm function.
3.Comes with magnetic grounding wire and clamp grounding wire, especially suitable for maintenance and inspection of subway lines.
