KH.DC Atmospheric Electric Field Meter

Lightning Detection and Early Warning for Meteorological Environmental and Infrastructure Monitoring

Product Introduction (pdf)

Product Introduction

The KH.DC Atmospheric Electric Field Meter is a high-precision lightning detection and early warning instrument designed for continuous real-time monitoring of atmospheric electric field variations.

It provides critical data for lightning disaster prevention, risk assessment, and environmental safety management. The solid-state aluminum alloy housing ensures long-term, reliable outdoor operation in harsh environments. Measured data is transmitted via RS485 communication, enabling seamless integration into meteorological stations, environmental monitoring systems, and intelligent lightning warning platforms.
