ProMinent names pool water and aquariums as the typical application for five distinct sensor types; the plastic-shaft PHEK/RHEK variants exist specifically for aquatic installs. Real detail: RHES Au uses gold electrodes because gold resists the hydrogen susceptibility that degrades platinum in pool water.

ProMinent's RHES Au uses gold sensor pins specifically because gold resists the hydrogen susceptibility that degrades platinum electrodes in pool water — a named material failure mode, not just generic corrosion, that platinum-electrode ORP sensors are exposed to in chlorinated pool chemistry.
Platinum is the default ORP electrode material almost everywhere except pool water, where ProMinent names hydrogen susceptibility as a real degradation mechanism and builds the RHES Au specifically with gold electrodes to resist it — the kind of chemistry-specific material substitution that separates a supplier who sells "an ORP sensor" from one who specs the electrode metal to the actual water it's sitting in.

FAQ
Is pH / ORP Electrode used in Aquatics / Aquariums / Water Parks / Zoos / Swimming Pools?
ProMinent names pool water and aquariums as the typical application for five distinct sensor types; the plastic-shaft PHEK/RHEK variants exist specifically for aquatic installs. Real detail: RHES Au uses gold electrodes because gold resists the hydrogen susceptibility that degrades platinum in pool water. This is strong evidence.
