Current Technology Evaluation

ACT is currently accepting preliminary applications from developers, manufacturers, and distributors of commercially available, in situ pH sensors interested in participating in independent performance testing.  ACT will review responses from interested parties and invite those with technologies that meet established criteria to submit a full proposal package.  This ACT Technology Evaluation will focus instruments that are designed for moored measurements of pH in freshwater, brackish and/or seawater, priority performance parameters identified by various pH sensor users, will be conducted in diverse coastal settings, and will be free of charge for qualifying applicants.  All results will be made available to the public in summary reports.

To qualify for this verification, candidate technologies must be:
A. Commercially-available
B. New, near-commercial technologies that are ready for the market with available quality testing data to support performance claims
C. Designed to measure pH in the type of field applications described above
