D.J. Gongol and Associates, Inc. is the manufacturer's representative for Analytical Technology, Inc. (ATI) water-quality monitors and toxic and combustible gas sensors in the states of Iowa and Nebraska. ATI is leading the way among manufacturers of sensors for use in a variety of municipal and industrial pollution-control applications.

The use of ozone for ultrapure water systems, cooling towers, aquatic farms, pharmaceutical-grade water, and potable water treatment has created the need to measure levels of dissolved ozone. The ATI dissolved-ozone monitor makes it possible to continuously measure dissolved ozone in the water stream without complicated maintenance or measurement interference from other sample components like residual chlorine.

The ATI dissolved-ozone monitor is able to measure ozone over ranges from 0-2.000 PPM to 0-200 PPM. It's easy to link your ATI dissolved-ozone monitor to external recorders or data loggers, using the built-in 4-20 mA output, and control relays and alarm relays are built into all standard ATI DO₃ monitors.

The sensing element exhibits excellent zero stability and is easy to maintain -- just make a quick and easy membrane replacement two to four times a year. Replacing the membrane in an ATI dissolved-ozone sensor takes no more than five minutes from start to finish. The sensor itself will last for years without any effort on your part, and the DO₃ transmitter, available in panel-mount and NEMA 4X housings, will continue to function reliably practically forever. Temperature sensing is built into the DO₃ sensor, and is displayed along with continuously-measured ozone levels on the monitor.

Putting an ATI dissolved-ozone monitor on line is easy -- just pipe your flows from a 1/4" sample inlet line into the ATI flowcell assembly sold with your DO₃ monitor, and release the tested water back to your stream. The ATI dissolved-ozone monitor doesn't foul your sample with chemicals, so it's perfectly safe to recycle your tested samples.

ATI is the leader in gas and water-quality sensing and monitoring, including dissolved-ozone measurement. Contact us for custom specifications and calculations.
