Functions

Lightning impulse detection – records each lightning current discharge, allowing accurate evaluation of lightning protection system load
Wide measurement range (1–100 kA) – detects both weaker and very strong lightning currents
Autonomous operation without power supply – does not require electricity, operates continuously and requires no maintenance
Mechanical 6-digit counter – clear and easily readable display without risk of electronic failure
Sealed IP68 enclosure – resistant to water, dust, moisture, and extreme weather conditions
Easy installation – mounted directly on the conductor without cutting or dismantling the system
Testing function – operation can be tested using a 9 V battery

Application

For residential users (homeowners): Allows understanding whether lightning strikes have occurred in the lightning rod, helps decide if inspection is needed after a storm, provides additional safety control
For engineers/designers: Used in lightning protection system design, enables collection of real load data, important for technical audits and compliance evaluation
For electricians/installers: Quick and simple installation without cutting wires, reliable solution for clients, does not require additional power or complex configuration
For industrial and facility maintenance specialists: Used in factories, warehouses, energy facilities, helps record lightning impact on equipment, important for safety documentation and maintenance planning
