The ATI D16 PortaSens III is the ideal device for locating leak sources or simply for measuring gas concentrations in the workplace. With a built-in sampling pump and inlet wand, samples are drawn from precise locations where leaks may occur. Areas around valve packing, flanges, compression fittings and other system components are easily checked to find the higher gas levels that exist near the leak site.

Modern Interface
The internals of the instrument are designed with a modern USB computer interface, a color touch-screen display, and improved pump control. The D16 detector has the ability to measure a wide variety of gases by simply inserting the appropriate sensor for that gas. The device can use any of over 60 different sensor modules, providing nearly unmatched flexibility. Sensors can be changed quickly and easily without the need for calibration.

Smart Sensor Modules
Sensors used in the PortaSens III are ATI’s H-Series smart sensor modules. Each sensor module is actually a sensor, amplifier, and memory module in one compact package. Because of this design, sensor modules can be calibrated independently and simply plugged into any detector for immediate use.

No Adjustments Necessary
When installed in a detector, calibration data is loaded into the microprocessor so that no adjustments are needed. The result is that a detector can, for example, go from phosgene measurement to ammonia measurement in less than one minute.

Questions & Answers
Are there any sensors supplied with the purchase of the D16 PortaSens III?
All sensors are sold separately. Please see the Accessories tab for a complete list of available sensors and ranges.
How long will the batteries last on the D16?
The rechargeable NiMH D-cell battery runs about 10 hours continuously. Alkaline D-cell batteries can also be used.
How often do PortaSens III sensor modules need to be calibrated?
Modules are calibrated at the factory before shipment. However, they should be recalibrated every 6-12 months (more often for dusty locations). Recalibration can be performed by the user or sent back to the factory.

Lake Malawi: A Treasure to Protect

Lake Malawi (also known as Lake Nyasa and Lake Niassa) doubles as a Rift Valley Lake and one of the seven African Great Lakes. Due to its unique biodiversity, it’s a great place to conduct limnological studies. Harvey Bootsma is a professor for the School of Freshwater Sciences at the University of Wisconsin-Milwaukee and has had an interest in limnology ever since he was a kid. Bootsma fondly recalls summer vacations to Georgian Bay, Ontario, “I probably spent as much time in the water as I did out of it.” He continues,”I remember telling myself ‘I’m going to get a job where I can stay here all the time.’” While Harvey didn’t end up working on Georgian Bay, he was offered a job working on Lake Malawi. He continued working there while completing his Ph.D.

Microbes and Human Health: Aquatic Microbial Communities May Hold Clues about How Deadly Pathogens Spread

Aquatic ecosystems are incredibly complex, with many different biotic and abiotic factors constantly interacting. Microbial communities are a key part of aquatic ecosystems, involved in the constant flow of energy and recycling of organic matter, according to Science Direct .  The true scope of microbial community impacts on aquatic ecosystems is still not entirely understood. Eric Benbow, a professor of community ecology at Michigan State University, is exploring how microbial communities and pathogens may be negatively impacting human health, and how a changing climate could worsen this problem.  How Do Pathogens Arise? Benbow, along with his students and colleagues, are studying a realm of community ecology that is still relatively unknown.
