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.

Data-Driven Decisions: Tracking Sediment during the Klamath Dam Removal

The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.

From the Tap: Source Water Monitoring for Public Health

In regions with historically secure access to clean drinking water, few think about the work that goes into ensuring that the water they fill their cups with is safe. In reality, millions of dollars are invested in the infrastructure, equipment and teams involved in converting source water into drinking water. While all the work that goes into providing clean water often goes unnoticed, analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, know exactly how much goes into securing safe water for millions of people. Gilkerson started with Battelle Memorial Institute in 1991 in their water ecology section. There, she saw how interesting source water monitoring could be, even though it isn’t often spotlighted in the environmental sector.

Choosing the Right Water Quality Monitoring Systems Is Crucial for Stantec Inc.

Data is king when it comes to water quality monitoring. It is not merely the type of data being collected that matters but also how that data is stored, processed and presented. When Joseph Kamalesh, a project manager with  Stantec Consulting Services Inc. , needs to find the right equipment for large client-based projects, he knows to keep these factors in mind. Joseph has a background in water quality and water flow monitoring instrumentation, which he continues to focus on at Stantec. During college and his early career, Joseph gained experience with water instrumentation, consisting primarily of on-site wastewater sampling and sampling small systems.
