Martindale Electric NC1 Non-contact Solenoid/Magnetic Field Tester, Yellow

Works as intended, signals a magnetic condition on gas suppression system solenoid. Perfect, cheap and reliable.

Arrived before delivery date. Exactly as described.

Too complicated for what I need. Keep switching the torch on by accident when turning the sensor on. The sensitivity isn’t low enough. We have older types, don’t know the name but they only light when there’s a working coil detected and at lower power than this can detect. Built well but I wouldn’t want to accidentally drop it in oil which happens a lot in my trade.

Bought this as it was a magnetic one that is better for detecting the different voltages we use in work. Didn't pick up supplies in cables, or energised coils. Borrowed friends one in case i was doing something wrong (different make) his worked perfectly. Waste of money.

Works well for me

Ideal for checking solenoids.

Useless It doesn’t work, doesn’t detect voltage at all.

advertised as able to do all. but i was disappointed that they were not sensitive enough to detect hydraulic control solenoids operating or automotive relays and it became obsolete for me on the first try out when i needed it

Funktion nicht gut.... Magnetfeld wird sporadisch angezeigt... Klumpp
