Measure the pH of high-purity water without the problems usually associated with low-ionic strength solutions. Concentric design and low sample flow rate (100 to 150 mL/min) help reduce streaming potential effects. Rugged 316 stainless steel system is grounded to prevent noise pickup and CO2 contamination. Electrode measures pH from 0 to 14 and withstands temperatures from 32 to 176°F (0 to 80°C). Order electrode, flow cell, and temperature compensation probe for a complete system. Electrode and temperature compensation probe sold separately.
