The Strike Guard total lightning detector and CS110 Electric Field Mill combine to classify lightning discharges within 20 miles and report electric field measurements to monitor overhead storm cell development. The dedicated lightning detector and field mill are integrated to display lightning threat levels based on customer-selected thresholds applied to data from both instruments.

Strike Guard with CS110 Electric Field Mill monitors cloud and cloud-to-ground lightning and the electric field within user-set parameters and provides contact-closure signaling at user-set thresholds.

The CS110 Electric Field Mill measures the vertical component of the atmospheric electric field at the Earth’s surface. Atmospheric electric field data is useful for assessing the local lightning hazard, especially prior to the first, and after the last, lightning discharges in a storm.

The International Standard for Thunderstorm Warning Systems, IEC 62793:2016, classifies Strike Guard with CS110 Electric Field Mill as a Class A Detector capable of detecting thunderstorm evolution during all four phases of thunderstorm development. The European Standard for Protection Against Lightning - Thunderstorm Warning Systems, EN 50536, classifies Strike Guard with CS110 Electric Field Mill as a Class I Detector capable of detecting thunderstorm evolution during all four phases of thunderstorm development.

Data from the two sensors can trigger automatic warning systems and help personnel make evacuation and shutdown decisions.
