DK-JS6 water-proof lightning strike counter is a universal type lightning counter. When the lightning protection circuit system is normal, there is no lightning current in the discharge line, the lightning counter don't count. When the lightning current is discharged to the ground, the lightning counter can induce it and counts correctly.
DK-JS6 water-proof lightning strike counter is suitable for all SPD, lightning rod, etc. It can induce the discharge current and count, and then display the number of lightning strike in the screen. This Lightning Counter can count accurately. If power failure, the operational data wonot lose. It takes the advantages of dust-proof and water-proof, etc.
