Utilizing sulfide ion selective electrode, Model SMS-22 provides user-selectable automated sequential sampling of sulfide ions in water. Multi-step process includes conditioning sample, measuring sulfide, neutralizing sample, measuring pH, and draining and rinsing cell. Offering adjustable sampling times from 2–10 samples/hr, system features measurement range of 0–5 ppm and up to 500 ppm using replaceable electrode cartridges. Accuracy is ±20 ppb or 5% of reading, whichever is greater.
