CSK6-NKW Electromagnetic Counter 6 Digit Pulse Counter (DC 12V)

Worked inconsistently out of the box. Device was returned.

excellent

I have been searching for a counter so that I could keep track of how many times my well pump comes on, and this counter does the trick. My well pump is 220v, but I bought the 110v counter since the 220v counter would have taken 3 weeks for delivery and the 110v only took 2 days.I hooked one lead of the counter to the pressure switch relay contact that gets power when turning on the pump and the other lead to my pressure switch relay ground, and it works great. Hooking it up in this manor gives me 110v, not 220v.I've only had it hooked up one day and I can see that my pump comes on much more often than I thought. Time for some fancy thinkin'.
