For Water Treatment Applications

The Model W1 is a dissolved ozone analyzer that uses state of the art UV absorption technology to measure dissolved ozone in relatively high turbidity water in drinking or waste water treatment applications.

The Model W1's stripping column converts dissolved ozone from solution to gas in order to determine the concentration of dissolved ozone. The ozone stripped out of solution has a direct relationship to the dissolved ozone originally in the water; therefore, by measuring the concentration of stripped ozone, an exact reading of the concentration of dissolved ozone can be produced. Unlike membrane-based technologies, this system is virtually maintenance free and requires no consumables.

The Model W1 UV analyzer is housed in a NEMA 4X industrial enclosure and features a backlit LCD Display, 4-20 ma analog ouput, 2 user programmable form C alarm relay contacts, RS-232 digital interface and instrument error relay.
