9185 sc Amperometric Ozone Analyzer

Description

Complete system (without controller) pre-assembled on a panel. The 9185 sc ozone sensor is a single-channel, online process ozone sensor that measures ozone in drinking water treatment plants, distribution networks and other applications where precise ozone concentration monitoring is required in the 0 - 2 mg/L O3 range. This instrument uses an amperometric measurement method. The membrane allows selective diffusion of ozone molecules to the amperometric sensor. The presence of a membrane eliminates the need for reagents. The measurement is pH and temperature compensated.

The system can be used with any Hach digital controller. Depending on the configuration, two to eight sensors can be connected to SC series controllers. Several SC controllers can be networked to accommodate more sensors and parameters, which reduces the cost of the measuring point.

Benefits of LXV433.99.00001

• When analyzing ozone concentration with the Hach 9185 sc, the presence of bromine, chloramines, chlorine, chlorine dioxide, hydrogen peroxide and pH does not affect the measurement.
• The 9185sc analyzer has a low minimum detection limit of 0.005 mg/L O3. Since the amperometric sensor is separated from the sample by a membrane and immersed in an electrolytic medium, the system is suitable for use in water with low conductivity.
• The sensor used in the 9185sc is a two-electrode amperometric sensor (gold cathode and silver anode) with an ozone selective membrane. The diaphragms are pre-assembled with special retainers to simplify and shorten service times. The maintenance itself is minimal, the kit includes all the necessary accessories for service for 2 years.
