pCO2 Buoy

The OceanPack™ pCO2 BUOY Analyzer was developed for precise measurements in shallow water. It is very small and easy to maintain.

LI-COR® produces LI-840x analyzers for SubCtech, which are built in exclusively for scientific demand. The analyzers are pre-installed and configured for the user. The auto-calibration allows long-term operations.

The Flat-Silicone-Equilibrator can be run under extreme conditions and even in rough seas difficulties do not occur.

Equipped with a data logger more probe heads, such as CTD, dissolved oxygen, pH, haze and nutrient analyzers amongst others, can be connected. The raw or calibrated and processing data is saved and transmitted in real-time.

An optional Top-Box can record data on Air-CO2 or meteorological parameter parallelly.
