Deep Abyssal Measurement of Oxygen and pH

The PyroScience AquapHOx-LX6 is a long-term logger for stand-alone underwater operation down to 6000 metres water depth for up to a year.

It can be combined with a broad range of PyroScience optical Oxygen or pH sensors for long-term monitoring down in the deep abyssal zone. A highly sensitive device, it can measure trace levels in oxygen minimum zones or de-oxygenation events and provide measurements of ocean pH on the total scale with negligible impact from salinity.
