Polestar Technologies Improves the Measurement of pH

Share Article

Polestar Technologies, a leader in sensor research, technology and product development, announces a dramatically improved optical sensing film for measuring pH. Long term stability has been a challenge for all techniques used to measure pH. Polestar’s new pH sensor has less than 0.1 pH units of drift over 2 months at a 10sec. sampling rate. This stability is equal to, or better than, any commercially available method for measuring pH. The new sensor also measures over a broad range of pH (5.5 to 10 pH units), has a high level of delivered accuracy (0.05 pH units), and a long lifespan (7M measurements).

Polestar’s optical sensors are used to measure pH, dissolved oxygen and carbon dioxide in biotechnology, pharmaceutical, biofuel, beverage, and other industrial applications. The new pH sensor is available in all the formats of Polestar’s current sensor films, including stainless bioprobes, peel and stick patches, flow cells and the iDOT for single-use bioprocessing.

About Polestar:
Polestar Technologies was founded in 1993 to conduct contract research for NIH, NASA, DARPA and many other government agencies. In the past 16 years the company has successfully applied an array of advanced technologies to solve difficult problems for customers. The company’s sensor products are the direct result of that research and are used by Fortune 100 companies worldwide. Polestar continues to perform critical research and technology development for the Department of Defense and other government agencies and develops new sensor products for the global marketplace.
