General description

The purpose of the EFA7 handheld electric field detector is to provide an early indication of the proximity of dangerous high voltages (typically from 6 to 110 kV), 50 Hz (optionally 60 Hz), to prevent electric shock due to unwanted violation of the safety distance. The detector measures the level of the fundamental harmonic intensity of the alternating electric field and, if the set level is exceeded, immediately alerts the worker by a strong signal to the dangerous situation so that he can react in time.

Key features

  • signaling of dangerous approach to a place where high voltage is present,
  • IP67-rated smartwatch case,
  • wrist mount,
  • suitable for outdoor and indoor electrical work,
  • an additional level of protection to prevent electric shocks,
  • light, sound and vibration alarm,
  • configurable levels of electric field detection according to the voltage levels of the grids used,
  • detector setup and FW update via Bluetooth,
  • Supporting application for mobile devices – Android OS,
  • active mode is automatically switched on by user movement – detected by accelerometer,
  • automatic shutdown after 1 hour of inactivity,
    battery life approx. 40 hours of active mode,
  • wireless charging according to Qi standard,
  • charging base is an optional accessory and is powered via USB,
  • battery status indication,
  • 7 optional colours, e.g. to distinguish voltage levels,
  • operating temperatures -20 to +60 °C,
  • charging temperatures 0 to +45 °C,
  • relative humidity 20 to 90 % non-condensing,
  • weight 50 g (without packaging).

Reasons for purchasing the product

  • the failure of standard security measures can never be completely prevented,
  • if the device is used correctly, this precaution is not dependent on
  • human factors,
  • it is the last warning when other measures fail.
