    EM1860A Wrist-Worn Proximity Alarm
  • Product Series : Wearable Proximity Alarm

    • Main Features

      When an electrician wears this alarm, it emits an audible and visual warning when they approach a live high-voltage conductor within a certain distance. The alarm indicates the appropriate safety distance based on the voltage level, reminding the electrician to exercise caution and prevent high-voltage electric shock accidents. This product can also be used for line fault detection and as a voltage tester
      Alarm Voltage Range: 1kV ~ 500kV
      Method Of Electricity Verification: Non-contact, automatic trigger
      Alarm Methods: Sound and light alarm
      Self-Test Function: Yes
      Protection Level: IP54
      Battery Life: 12 Months
      Power Supply: CR1632 Button Cell Battery

    Product Introduction

    EM1860A wrist-worn proximity alarm is a new, safe, practical, and convenient high-voltage alarm device designed for workers performing live-line operations. During live-line work, the safety distance between the operator and live conductors must not be less than the requirements specified in relevant work procedures. The alarm has no power button. Once worn by the worker, the device detects the electric field in the air. When approaching high-voltage live parts, based on the safety distance corresponding to the voltage level, the alarm automatically triggers an audible and visual alert if the detected electric field exceeds the threshold, reminding electrical workers to stay safe and preventing high-voltage electric shock accidents.
    EM1860 series of wrist-worn live-line detectors is available in two models: a high-voltage detector (for voltages above 1 kV) and a low-voltage detector (for voltages below 1 kV). Utilizing non-contact sensing and low-power technology, these devices are energy-efficient and durable, with a standby time of up to 12 months. The detectors feature a self-test function to ensure the safety of workers performing live-line operations. They are widely used in live-line work environments across the power, railway, and industrial sectors.
    ETCRMETER is a high-end brand of ETCR. All products are manufactured by ETCR, which also provides technical support and after-sales service.


    Product Features
    1. The alarm is worn on the worker’s wrist and provides comprehensive detection of the electric field in the air with high sensitivity.
    2. No power-on is required; the alarm is automatically triggered when the detected electric field exceeds the threshold, ensuring the safety of workers performing live-line operations.
    3. Utilizing non-contact sensing and low-power technology, it is energy-efficient and durable, with a standby time of up to 12 months.
    4. Protection Level: IP54
