EFM-100C Electric Field Mill

  • Measuring the static electric field generated by thunderclouds the Boltek EFM-100 not only detects nearby lightning but can detect the atmospheric conditions which precede lightning. Electric field data is displayed and graphed on your desktop computer using the included software.

    The EFM-100 Electric Field Mill short-range sensor constantly monitors for lightning and activates graphical display alerts on a PC or laptop when lightning is detected. There are two high electric field alarms, and lightning distance ranges that are completely customizable to alert the user when there is nearby lightning. The software will also reset back to a green All Clear state when no lightning has been detected within the configured time period and when the electric field levels fall below their set levels.

    The EFM-100 features aluminium and stainless steel construction for corrosion resistance, gold plated connectors throughout, and the highest quality ball-bearing motor for excellent reliability.
