Steam-sterilizable pH sensor resists cracking
Autoclavable and steam-sterilizable pH sensor <br/><br/>
The Rosemount Analytical PUR-Sense 3800 from Emerson Process Management is an autoclavable and steam-sterilizable pH sensor that reportedly delivers sensor stability as much as five times greater than any other pH sensor. High temperature can cause deterioration of a pH glass sensing membrane; however, the AccuGlass pH bulb on the Rosemount Analytical PUR-Sense 3800 resists cracking and aging and exhibits near theoretical response even at extreme pH values, according to an Emerson Process Management spokesperson.
In simulated cell-culture process, the product exhibited sensor drift below 0.1 pH after an autoclave of 125 °C for 45 minutes. Testing showed continued sensor life after more than 30 autoclave cycles or 50 steam cycles. PUR-Sense reference electrode uses a silver-silver chloride-based reference electrode in combination with a new gelled potassium chloride electrolyte to provide a stable reference potential through the single proprietary ceramic reference junction. It provides an individual quality certification with calibration records and list of wetted materials for each sensor.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
