Electro-Chemical Devices SMS-22 Sulfide Ion Measurement SystemThe SMS-22 Sulfide Ion Measurement System from Electro-Chemical Devices, Inc., (ECD) 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.

The ECD SMS-22 is a sequential sampling analyzer. Featuring automated sequential sampling, the Model C-22 Analyzer controls the sequential sampling with a combination of relays and timers. Sampling times are easily adjustable from two samples per hour to 10 samples per hour.
