ORBISPHERE 3231X

The High Precision Calibration Kit is a unique solution that calibrates and verifies ORBISPHERE carbon dioxide analyzers. It is designed to give a traceable and trustworthy calibration standard with defined carbon dioxide content to + / - 0.5 %.

The calibration solution is prepared in a precision calibration bottle. A known and precise amount of sodium bicarbonate powder is combined with a ready-made dilute citric solution to provide a defined, accurate carbon dioxide concentration in the liquid. This liquid can then be circulated through the flow chamber of the Thermal Conductivity sensor to enable calibration or quick validation.
