Electroplating rinse water contaminated with cyanide or hexavalent chromium needs a double-junction sensor, not a standard single-junction pH probe — ProMinent's PHED is built specifically with a 2x ceramic double-junction diaphragm for this contaminated-media service, rated to 80°C/8 bar, distinct from the plain PHEP/PHES sensors quoted for clean drinking or process water.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
