This is a top of the line dissolved ozone monitor.

In operation, ozone diffuses through a membrane at the tip of the sensor and is reduced to oxygen. The reaction causes current to flow between the sensing and counter electrodes, with the current being directly proportional to dissolved ozone concentration. In essence, the sensor operates like a battery, with zone causing current to flow. Since the sensor consumes ozone in the measurement, sample flow is required for measurement.

The A15/64 monitor is provided with a constant head overflow chamber which automatically regulates the sample flow past the sensor. Flow variations at the inlet to the overflow cell have no effect on the ozone measurement, insuring the highest possible data validity. The flowcell is made from clear cast acrylic, allowing the user to view the condition of the membrane without removing the sensor from the flowing sample. The sensor inserts into the side of the flowcell and is sealed in place by double o-rings. For systems requiring a flow system that is not open to atmosphere, a sealed flowcell with 1/8" FNPT fittings for inlet and outlet connections is available.

In low range, the monitor displays ozone over a range of 0-2.000 ppm with a resolution of 0.001 ppm (1ppb). In high range, the display is 0-20.00 with a resolution of 0.01 ppm. For special applications, a high range system of 0-200 ppm is available. An isolated 4-20 mA output may be programmed for external recording or data logging. This output may be programmed for any required span using the front panel switches and may be changed to 0-20 mA and used with a shunt resistor to provide zero based voltage outputs if required.
