- Measuring water pH is important for many applications. In particular, ocean pH is key to monitoring climate change. Most potentiometric pH sensors are limited in range and drift in the long-term, providing inaccurate measurements, whilst voltammetric pH sensors fail in unbuffered solutions because local pH perturbations occur during operation. In this research an entirely new approach to voltammetric pH measurements was and applied in an ocean pH sensor, which received runner-up prize in the Wendy Schmidt XPrize on Ocean pH monitoring in 2015 (https://arstechnica.com/science/2015/07/winners-of-xprize-ocean-acidification-prize-announced/), and is being adapted for commercialisation by ANB Sensors (Steve Gahlings: sgahlings@anbsensors.com).
