How to check Solenoid valve works (Solenoid Checker)

This device makes it possible to quickly determine whether the coil of the solenoid valve is normal or not.
Where a large number of solenoid valves are used, a faulty solenoid valve must be found quickly.
It can be usefully used in chemical plants or power plants.

Nice. I like the LED for indication. In the past I used a long 1/8" flat screwdriver above the coil solenoid to since the screwdriver vibration with my fingers on the handle.

I used to use a small magnet in the same way.
