DO monitoring in wastewater aeration systems, effluent channels, or natural waters are easily handled by the Q46D on-line monitoring instrument.
Dissolved Oxygen monitoring is critical for aeration system process control. Optimization of the biological process, whether it’s removal of organic material, nitrification, or nitrification/denitrification, depends on maintaining proper D.O. levels. Controlling air flow to within the optimal range eliminates excess aeration which translates into significant energy savings.
ATI’s Model Q46D Dissolved Oxygen Monitor is designed to provide reliable oxygen measurement and help reduce operating costs. Two types of sensing technologies are available for use with the Q46D system: Membraned Electrochemical and Optical (fluorescence). Both sensors will provide reliable long-term performance with minimal maintenance. No hardware modifications are required to change from one sensor type to the other. The monitor can be configured for AC or DC power supplies, and a portable battery-powered unit is available to meet a variety of monitoring needs.
When process conditions require frequent sensor cleaning, our unique Q-Blast Auto-Cleaner can be used to keep the system operating nearly maintenance free. This time-proven system has been instrumental in providing years of worry free operation.

What is the Q-Blast option?
The Q-blast is an option that allows the sensor to be cleaned without a visit to the field site. Pulses of pressurized air is delivered through a nozzle at the tip of the sensor to remove accumulated solids from the critical sensing surfaces. Cleaning frequencies can be set depending on fouling and usage needs.
How often does the optical sensor disk need to be replaced?
The disk has a life of 2-5 years depending on usage.
Can I switch between optical and membrane type sensors?
Yes, no hardware modifications are required to switch between sensor types.
Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.Read More
We've all felt the frustration of weeding through a school of dinks to catch a "keeper." Often the small fish outnumber the bigger ones and they are typically more aggressive. Sometimes there's no choice but to deal with it, as is often the case with open water fishing. However a frozen lake involves a vertical presentation and a stable platform, it's a perfect situation to pick and choose which fish you want. Once you locate a school and get set up it's time to start sizing them up with a FishSens SondeCAM underwater fishing camera. It can be mind-blowing just how big some of these schools of fish are and also how outnumbered fish of a desirable size can be.Read More
It’s no secret that anglers have been the means by which invasive species and non-native fish have spread to new water bodies in the past. Fishermen have even been known to transport some of their favorite fish to new areas on purpose so that they can catch them a little closer to home. And the results of those actions have not always been ideal. In Ontario, Canada, fishermen have taken non-native bass and stocked them into what were historically lakes dominated by brook and cutthroat trout. The actions have impacted ecosystems, but scientists have been unable to broadly study the effects because they didn’t have enough data. But that is no longer the case for some Ontario lakes, as a study from biologists at the University of Toronto shows.Read More
