    Arm type high voltage detector provides a safe, practical, and convenient new high-voltage alarm device for near-electricity operators, high voltage alarm is worn on the upper part of the outermost arm of the operator's work clothes, with a unique automatic trigger detection function to ensure the safety of personnel working with electricity.

    Arm type high voltage detector

    Sound and light alarm, safe and fast

    • Arm-type high voltage alarm provides a safe, practical, and convenient new voltage alarm device for high-voltage near power operators.
    •  High voltage tester uses non-contact induction technology, accurate alarm, power saving and durability, and standby time up to 12 months.
    • All-round induction voltage source, automatic trigger detection mode, and sound and light alarm mode, to ensure the safety of personnel working near electricity.


    A non-contact high-voltage tester (with voltage indication) is specially manufactured for high-voltage transmission line inspection, high-voltage transmission line-to-ground voltage, induced voltage test, and current test. High-voltage alarms are widely used in electric power, railways, industrial and mining enterprises, and other near-electrical workplaces.

    How to wear arm type high voltage detector

    Voltage Rating and Alarm Distance

    Arm type high voltage detector voltage level and alarm distance


    Q1: What is the high voltage tester used for?
    A1: A high voltage tester is widely used in substations, power plants, fire departments, industrial and mining enterprises, electrician maintenance departments for power detection and field electrician work, etc.

    Q2: What is a high-voltage electroscope?
    A2: High-voltage electroscope is a tool used to check whether high-voltage lines and power equipment are live, and is a basic safety tool commonly used in 
    substations. The high-voltage electroscope is used to check whether the line or equipment is charged, the purpose is to ensure personal safety.

    Q3: How to divide the high voltage tester level?
    A3: According to the applied voltage level, a high voltage tester can be divided into: 0.1-10KV detector, 6KV, 10KV detector, 35KV, 66KV detector, 110KV, 220KV detector, and 500KV detector.

    Tips: Why do you need a high-voltage alarm?

    When you wear a high-voltage alarm and mistakenly enter a charged area and mistakenly climb a charged pole, the near-electricity alarm can issue a continuous audio alarm signal in time to remind the operator of the danger and prevent electrocution casualties caused by misperceptions and mistakes. After years of use in electric power, railroad, oil field, chemical industry, coal mine, and other departments, it has proved to have the effect of ensuring personal safety and has produced a good economic effect.
