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?


Why do you want to use stainless steel rods, and how?

Are you going to pass a current through them ?

Why not get a water level sensor - CPC sell them at a reasonable price
(about 7 quid IIRC)
