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 9185 sc Amperometric Ozone Sensor, which can measure from 0 - 2 mg/L ozone.

Ideal for Low-Conductivity Samples

The 9185 sc 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 9185 sc ozone sensor is suitable for use in water with low conductivity.

Reliable Amperometric Measurements

The sensor used in the 9185 sc 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.

Easy Setup and Maintenance

The all-inclusive 9185 sc ozone system comes preassembled on a panel. The membrane system of the sensor means there are no chemicals used for measurement.

Compatible with Hach's "Plug and Play" Digital Controllers

The 9185 sc Ozone Sensor is designed to be used with all Hach digital SC controllers. Set up is fast and easy, and the system is compatible with the full line of Hach digital sensors.
