The Model 499AOZ sensor a membrane-covered amperometric sensor for the continuous determination of dissolved ozone in water. The major applications are measuring ozone in municipal drinking water and in bottled water and soft drinks. Other applications include semiconductor and pharmaceutical manufacturing and food processing.

Sensor maintenance is easy. Replacing the membrane requires no special tools or fixtures, and replacing the electrolyte solution takes about 15 seconds.

The sensor is available with both integral cable and quick disconnect cable (Variopol) options.

• AVAILABLE IN FOUR LENGTHS between 120 and 425 mm
• PG 13.5 PROCESS CONNECTION
• TOLERATES REPEATED STEAM STERILIZATION
• SENSOR RESPONSE PRACTICALLY INDEPENDENT OF FLOW
• FAST RESPONSE TIME

The Model GX448 sensor is a membrane-covered amperometric sensor designed to meet the demanding requirements of the biotechnology, pharmaceutical, and food and beverage industries.

The sensor combines ruggedness with high performance. The steel-mesh reinforced membrane tolerates high temperature and pressure as well as repeated SIP cycles, but still provides high sensitivity and fast response times.

The sensor is available in four lengths and has a PG13.5 process connection.

The Model 499ATRDO sensor is a membrane-covered amperometric sensor. It is primarily used to measure trace oxygen levels in deaerated boiler feedwater in steam electric power plants.

• HIGH ACCURACY: + ppb error below 20 ppb
• RAPID STABILIZATION following calibration or maintenance.
• EASILY REPLACEABLE MEMBRANE, no special tools required.
• AUTOMATIC COMPENSATION FOR CHANGES IN MEMBRANE PERMEABILITY
• VARIOPOL CONNECTOR OPTION allows the sensor to be replaced without running new cable.
