Portamap portable oxygen and carbon dioxide headspace analyzer

This product is now know longer available and has been replaced by the GS6000 headspace analyser. Please call us if you need any technical support. 

The Portamap portable gas headspace analyzer is specifically designed to test for the presence of oxygen and carbon dioxide in food packaged under modified and controlled atmospheres. The portable oxygen and carbon dioxide analyzer is simple to use and is powered by maintenance-free batteries which can be recharged by simply connecting the analyzer to the mains supply.

The Portamap utilises the Systech Illinois electrochemical fuel cell for oxygen analysis and an infra red sensor for carbon dioxide analysis. Unlike many electrochemical cells, this cell is unaffected by carbon dioxide.

Testing is done by simply inserting the needle probe into the package for test and pressing a switch on the front panel to start the internal sample pump.

The analysis of the gas is then shown on the LCD display.  Periodic calibration can be carried out using air or a calibration gas.

This portable gas analyzer is robust in construction and is unaffected by vibration or operating position.  It is not flow sensitive or affected by changes in atmospheric pressure.
