pCO2 Analyzer

The OceanPack™ pCO2 analyzer was developed as a high-end analyzer for precise measurements under rough sea conditions. It is very small and easy to maintain.

LI-COR® produces LI-840x analyzers for SubCtech, which are built in the MK2 exclusively for scientific demand. The analyzers are pre-installed and configured for the user. The auto-calibration allows long-term operations. More pCO2 analyzers are available.

The OceanPack MK2 Lab-Analyzer is built sturdy and is easy to maintain. The Flat-Silicone-Equilibrator can be run under all conditions meaning there are no difficulties in using it on ships or vehicles.

Leading scientists from NIOZ, AWI, GEOMAR and IFREMER attended the development of the OceanPack.

Product overview:

Our standard OceanPack™ analyzers:

MK2 Analyzer with external gas inlets for span gas calibration (left side) and connectors for external data loggers and additional sensors such as pH or TSG (temperature, salinity) Easy to maintain Flat-Silicone-Equilibrator (patent pending). With few screws cleaning is done in 3 minutes

Inter-calibration test of different SubCtech analyzer models on board the German ATAIR in the North-Sea 4 weeks pCO2 data – 1.5 Mio. Datasets - in the North-Sea on board PELAGIA. The lines down to zero are calibration cycles. The 3 high concentrations are harbours.

Calibration and diagnostic control elements for the OceanPack™ pCO2 analyzer. A PC monitor and keyboard can be connected. The calibration for zero and optionally span1 and span2 can be performed manually
