    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: Precautions for using the wrist-type high voltage alarm

    1. Place the wrist alarm on the bare skin of the wrist and hold the case close to the skin so that the triangular symbol on the surface of the alarm faces the direction of the fingertips.
    2. If the alarm is placed on the sleeve of work clothes or on rubber gloves, the sensitivity will be greatly reduced.
    3. When close to a grounded metal structure (such as a transformer), the working distance of the alarm will be greatly reduced.
    4. When the alarm is wet by rain, please remove the battery and blow it dry naturally in a cool place. Do not use the alarm when it is wet. The working distance of the alarm will be greatly shortened, and the alarm may even keep sounding the alarm.
    5. If the alarm is dropped or hit by a strong external force, check the appearance of the alarm and test it by pressing "TEST" to make sure the alarm functions properly.
    6. The alarm-sounding area is covered with a waterproof film, so please do not use pins or other pins to damage it.
    7. If the alarm keeps sound and light indication, it may be affected by the surrounding environment, such as strong induction voltage, static electricity, etc. When the alarm is covered with both hands and shields the surrounding influence, the alarm operation (sound and light) stops, indicating that the alarm is normal.
