Ozone Analyzer features reagent-less sensor design.
Press Release Summary:
Factory assembled and calibrated, Model OZ80 uses amperometric sensors to detect and monitor O3 levels in water. Plumb and play design only requires user to mount panel, connect drain lines, plug in power cord, and select outputs on display as 0–2.0 ppm for water disinfection or 0-20.00 ppm for oxidation and bleaching operations. Constant head flow control device maintains optimum flow rate for sampling purposes. Standard configuration features two 4-20 mA outputs, 3 alarm relays, and MODBUS RTU.
Original Press Release:
Plumb and Play OZ80 Ozone Analyzer with Reagent-less Sensor Design for Low Operating Costs
Ideal for Municipal Water Treatment, Food/Beverage, Pulp & Paper and Cooling Towers for Electric Power Generation and Petrochemical Refining
Irvine, CA—The new plumb and play OZ80 Ozone Analyzer from Electro-Chemical Devices features a reagent-less design for low operating costs and offers a choice of three factory calibrated measurement ranges designed to help busy process and plant engineers achieve accurate measurement with a simple easy-to-install system that can be up and running in less than 15 minutes.
Unlike conventional analyzers that come with multiple components that must be installed and then require field calibration, the OZ80 Analyzer is factory assembled and factory calibrated prior to arriving at the plant. All the technician needs to do is mount the panel and connect the drain lines, plug in the power cord and select the outputs on the display as 0 to 2.0 ppm for water disinfection or 0-20.00 pm for oxidation and bleaching operations.Â
Dual range measurement of both Ozone (O3) parameters also is available with the OZ80 Analyzer. O3 is a colorless to pale blue gas that in low concentrations gives off an irritating acidic odor. It is a strong oxidizer, stronger than either chlorine (Cl) or chlorine dioxide (ClO2). O3 reacts quickly and disintegrates into oxygen gas without the formation of harmful disinfection byproducts (DPB’s) common to chlorine disinfectants that require additional costly treatment. It also increases the amount of oxygen in the water.
O3 is widely used in municipal drinking water and wastewater treatment plants. It is useful at several points in the drinking water treatment process as an oxidizer for removing metals from well water as well as organics, odors and color from surface water too.   Industrial uses for O3 include food/beverage processing, pulp/paper manufacturing and as a bactericide for industrial cooling towers used in the electric power generation, oil/gas refining and petrochemical production.
The OZ80 Analyzer features powerful amperometric sensors to detect and monitor O3 levels in water. These amperometric sensors are manufactured with a gold cathode, a silver anode and a rugged microporous membrane. Unlike many other analyzers, there are no reagents required with the OZ80 Analyzer. Its O3 sensor technology and pH measurement are reagent-less designs. These sensors keep the cost of ownership low by not requiring expensive reagents.
The O3 sensors are smart sensors with their identity and calibration information stored internally. Communication between the OZ80 Analyzer’s T80 Transmitter and the O3 sensor is via MODBUS. The sensors are flow sensitive requiring a minimum flow rate of 0.5 ft/sec, above this flow rate, the reading is virtually independent of the flow rate.Â
The OZ80 Analyzer’s constant head flow control device (CFD) maintains the optimum flow rate moving past the sensor for sampling purposes. The CFD’s automatic flow control capability eliminates the need for pressure regulators and rotameters, which are required by many other H2O2 analyzers, to reduce system maintenance and lifecycle operating costs. The minimum flow rate required by the CFD is 10 gal/hr, and the maximum flow rate is 80 gal/hr with the sample draining at atmospheric pressure.
The OZ80 Analyzer is available with an optional sensor auto clean configuration. The sensor auto clean features a solenoid actuated spray cleaner that provides either a 30 psi process water or air. The spray cleaner removes films from the sensor head, which over time can affect measurement accuracy. There is rarely a need for manual wiping of the sensor head by maintenance technicians with the spray clean configuration.
Designed with ECD’s T80 Universal Transmitter, the OZ80 Analyzer includes a 128-x-64 pixel (2.75-x-1.5-inch) display. The display is black on grey with no backlight or blue on a white background with the LED backlight. The standard configuration features two 4-20 mA outputs, three alarm relays and MODBUS RTU. The enclosure is rated to IP65 and weatherproof.
