AquaMetrix 500 Series combination pH/ORP sensors use conventional measurement technique with a process pH glass electrode (platinum for ORP) compared to a reference electrode in KCl solution. Convertible design allows use in flow‑through and submersion applications, minimizing inventory requirements. Offered with or without temperature compensation.

Measurement range: 0–14 pH, ±1000 mV ORP. Sensitivity 0.01pH / 1.0 mV. Stability 0.05 pH per day / 3 mV per day. Flow rate 10 ft/sec, temperature limit -5–80°C, pressure limit 100 psig at 65°C. Direct connection to Shark, SharkTX/P, and 2200P/R analyzers within 10 ft cable; preamplifier options for longer transmission.

Applications: process control, water/waste treatment, fume scrubbers, plating, food/beverage, chemical processing, pulp/paper, mining, power generation, pharmaceutical.
