I need some stainless steel rods to act as water level sensor probes for
my fishtank, does anyone know where I can get hold of some?


Keep in mind, stainless is not really stainless. They will eventually
oxidize and rust. Just not as quick.



I think titanium will hold out longer in water. Also look into float
swit , hey are usually better for aquarium use. I'm assuming you will
be doing some kind of connectivity measurement to see if electricity can
flow between two rods, right? If it can, then water is touching it.
However, this would mean you would have electrical currents in the water,
which might affect your fish badly.
