Agasthya 2013 Series Handheld O2 Headspace Analyzer BI 4000 is specifically designed to test for the presence of oxygen in food packaged under modified and controlled atmospheres.

The instrument is simple to use and is powered by maintenance free rechargeable batteries which can be charged by simply connecting the Analyzer to the mains supply. The analyzer uses electrochemical fuel cell for oxygen analysis.

Testing is done by simply inserting the needle probe into the package for test and pressing a PUMP ON/OFF key 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. It is robust in construction and is unaffected by vibration or operating position. It is not flow sensitive or affected by changes in atmospheric pressure.
