ATI Q46H/62-63 Residual Chlorine Monitor
- Monitors are factory set for either Free or Combined Chlorine, but can easily be converted from one to the other in the field
- Reagent-less operation for potable water, wastewater, cooling water, or high purity water systems
- Options available for Profibus-DP, Modbus, or Ethernet digital output

ATI's Model Q46H/62-63 Residual Chlorine Monitor is an upgraded version of the proven Q45H system for continuous monitoring of free or combined chlorine. Monitor capabilities have been expanded to include options for a third analog output or additional low power relays. Digital communication options for Profibus, Modbus, and Ethernet are also available with this monitor.
The Q46H system uses a polarographic membraned sensor to measure chlorine directly, without the need for chemical reagents. When needed, automatic pH compensation may be added for increased free chlorine measurement accuracy. Systems are available to provide outputs for chlorine, pH, and temperature to allow easy Contact Time (CT) calculations.

While much of the world has experienced a warmer climate in recent years, the U.S. Southeast has cooled. Scientists want to know why because the answer could reveal keys to improving air quality and understanding climate change.
To study the cooling Southeast, scientists at several institutions have joined forces to conduct the Southern Atmosphere Study (SAS), the largest study on southeastern U.S. air quality since the 1990s. These include the U.S. Environmental Protection Agency, National Center for Atmospheric Research, National Science Foundation, National Oceanic and Atmospheric Administration and the Electric Power Research Institute.
Five air quality studies fall under the SAS umbrella.Read More
A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek.
As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow.
Much of the original property and surrounding land has fallen prey to urban sprawl.Read More
Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die.
Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn.
This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area.
“‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters.
This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.Read More
