Track Real-Time Strike Events for Safety & Maintenance | Battery-Free | Resettable Counter | Weatherproof Design
The TEKSAI Lightning Strike Counter is a non-powered, electro-mechanical device that records the number of lightning strikes captured by your lightning protection system. Installed directly on the down conductor, it provides real-time data for maintenance scheduling, safety audits, and strike frequency analysis.
This innovative device operates entirely without batteries or external power sources, making it ideal for remote installations and maintenance-free operation. The counter mechanism is triggered by the electromagnetic field generated during a lightning strike, ensuring accurate recording without any electrical connections.
Designed for long-term reliability, the TEKSAI Lightning Strike Counter features a resettable counter mechanism (0-999 count range) and weatherproof housing that withstands harsh outdoor conditions. Perfect for integration with TEKSO PREVENT conventional lightning protection systems and other lightning protection installations.

Detailed specifications for reliable lightning strike monitoring and recording
Essential monitoring tool for comprehensive lightning protection system management
Document strike frequency and system performance for compliance audits and insurance requirements.
Plan preventive maintenance based on actual strike data rather than estimated schedules.
Verify system effectiveness and identify potential issues through strike frequency analysis.
Monitor individual down conductor performance in multi-conductor systems.
Analyze strike patterns to optimize protection system design and identify high-risk periods.
Maintain records of lightning activity for regulatory compliance and certification purposes.
Simple installation process for seamless integration with existing lightning protection systems
Choose a location on the down conductor, typically 1-2 meters above ground level for easy inspection access.
Attach the counter using the provided clamp mechanism, ensuring firm contact with the down conductor.
Check that the counter display is visible and readable. Reset counter to zero if needed for new installation.
Record the initial counter reading and installation date for future reference and maintenance tracking.
The counter should be installed on the down conductor, not on the air terminal or grounding electrode. Ensure proper contact with the conductor for accurate detection.
