9185sc Ozone Analyzer with sc100 controller and RS-485
Product #: 6043301


Few Interferences from Oxidants or pH over a Wide Measurement Range

Bromine, chloramines, chlorine, chlorine dioxide, hydrogen peroxide, and pH do not interfere with ozone measurements using the Hach 9185sc Amperometric Ozone Sensor, which can measure from 0 to 2 mg/L ozone.

Ideal for Low-Conductivity Samples

The 9185sc ozone system has a low minimum detection limit of 0.005 mg/L ozone. Because the amperometric cell is separated from the sample by the membrane and is immerged into an electrolytic medium, the 9185sc ozone sensor is suitable for use in water with low conductivity.

Reliable Amperometric Measurements

The sensor used in the 9185sc system is a two-electrode amperometric sensor (gold cathode and silver anode) with a membrane selective to ozone. Membranes are pre-mounted on retaining caps to simplify and reduce maintenance time.

Flexible Options

Options available for the 9185sc ozone system include: Acidification Unit, which can be used intermittently or continuously for cleaning and is fully programmable, and Intermittent Flow Unit, which is fully programmable and saves resources while limiting excess flow to drain.

Easy Setup and Maintenance

The all-inclusive 9185sc ozone system comes pre-assembled on a panel. The membrane system of the sensor means there are no chemicals used for measurement. Maintenance is minimal and two years of typical maintenance items are included with the system.
