    yes they do work but to varying degrees.

    buy a cheap one and it may no be very selective.....dry or wet and nowt inbetween.

    an expensive one will maybe show a degree of dampness.

    they work on resistance of the material being tested....very dry and very high resistance...no current can pass between the probes.
    very wet and very low, if any, resistance so current can pass and the meter needle/lcd can swing.:thumb:

    basicaly a very sensitive Ohm meter.

    I think you can worry yourself to death doing your own analysis.
