Electro-Chemical Devices SMS-22 Sulfide AnalyzerWith its all-in-one design, the new SMS-22 Sulfide Ion Measurement System from Electro-Chemical Devices, Inc., (ECD) can be quickly installed with no special tools. The SMS-22 features user-selectable automated sequential sampling of sulfide ions in water and lowers plant technician and supply maintenance costs. In addition to odors, excessive concentrations of H2S in wastewater can lead to corrosion and structural damage to municipal water/waste infrastructure including equipment and piping. The SMS-22 Sulfide Measurement System saves time and labor costs for municipal water operations by completing all the necessary steps to measure sulfide ions in a water sample. Because sulfide ions only exist at high pH values, this is a multi-step process. The SMS-22 conditions the sample, measures the sulfide, neutralizes the sample, measures the pH and drains and rinses the cell. After measurement, the highly caustic sample pH is reduced to a safe level near pH 8.
