pCO2 Monitoring System

Challenge

A functioning laboratory proof-of-concept is needed in larger volumes, at lower cost, and with higher reliability.

Solution

Autonomously deployed, high accuracy ocean-measuring partial pressure carbon dioxide sensor system. The partial pressure carbon dioxide sensor (pCO2) is another design that transitioned laboratory proof-of-concept functions to products that are currently deployed around the world. Manufacturing quality ensures successful 18-month autonomous ocean deployments, after which the systems often are returned to Battelle for refurbishment. pCO2 is an ongoing, low-volume (typically one system per month), high-precision sensing instrument manufacturing project. These systems are also sold and shipped internationally. 

Outcome

Design successfully transitioned and cost-reduced, with five years of ongoing manufacturing the sealed, electro-pneumatic system, meeting reliability requirements, and performing regularly scheduled refurbishment.
