D.J. Gongol and Associates, Inc. are the manufacturer's representatives 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.

It can be difficult to ensure that the same water that leaves a municipal water-treatment plant arrives at distant taps with the same quality and safety it had when it was first pumped out. While continuous monitoring of some parameters can be effectively performed with other water-quality monitors, remote testing is also necessary for some temporary applications.

ATI has responded to this need with the development of the PQ45 portable water-quality monitor and data-logger. The PQ45 can be used to monitor a wide range of parameters:

• free chlorine
• combined chlorine
• pH
• dissolved ozone
• residual chlorine dioxide
• dissolved oxygen
• conductivity

The entire unit is run by two C-cell batteries, and those two batteries can provide 30 days of continuous monitoring and automatic data-logging. Solar-powered options are available as well. All you need is a sample line and a drain line. All flow and pressure controls come built-in, and the connections are made through self-sealing fittings.

The most popular application is for residual chlorine and pH, but these units, mounted in sealed, lockable cases, are versatile and affordable for almost any application. Send your inquiry now!
