Lightning counter

High sensitivity lightning strike counter.

The CDR-HS high sensitivity lightning strike counter is designed to detect electro-atmospheric discharge impacts through the down-conductors of the external protection system. The high sensitivity in the current detection makes the CDR-HS the ideal solution for protection systems as conductive mesh and protective down-conductors in contact with metal walls. These kind of protection systems are characterized by having various current return paths which make more difficult the detection of lightning of low and medium intensity by an Standard lightning counter (based on the Standard IEC 62.561/6:2011). The use of the CDR-HS is recommended in:

  • Faraday cages with various current return paths.
  • Down-conductors in contact with metal walls, in case that metal walls are grounding.
  • When the down-conductor has various anchor sets in a metal wall and the lightning counter is situated in the middle of them.


  • High recording sensitivity.
  • Great register capacity (999 impulses).
  • Easy visual control.
  • Detection of impulses from:
    • Intensity min: 1kA (8/20μs according to 62.561-6:2011).
    • Intensity max: 100kA (10/350μs according to 62.561-6:2011).
  • Compact and robust design.
  • Durability.
  • Easy adaptation to the down conductor of any lightning protection system.
  • Allows controlling the lightning rod condition.
  • Works in any atmospheric condition (from -20ºC to 65ºC).
  • It does not need power supply.
  • Easy installation and operation.
