Headspace Oxygen Analyzer

Measure the residual oxygen in any gas-flushed (MAP/CAP) food package by using the Headspace Oxygen Analyzer. The battery life of the Headspace Oxygen Analyzer is long. Also, the design of Headspace Oxygen Analyzer is compact, making it easily portable. The Headspace Oxygen Analyzer is calibrated with normal air.

Modified Atmosphere Packaging (MAP) helps in preserving the food products in an atmosphere that has been modified to increase the shelf life of the packed products. The three main gases used in modified atmosphere packaging are O2, CO2 and N2. The head space of any packaging contains any one of these gases or a mixture of these gases and the success of packaging depends on the packer's ability to correctly prepare the product and to control the concentrations of head space gas within the desired limits.

In case of N2 or CO2 flushed packaging, the Head Space Oxygen Analyzer helps to measure the quality of modified atmosphere by detecting raised levels of Oxygen. The analyzer can also be used to determine the Oxygen concentration where the modified atmosphere is oxygen enriched (50-100%). The Headspace Oxygen Analyzer uses a syringe needle sampling assembly to pierce the package and draw a sample into the analyzer for oxygen measurement. The oxygen sensor used in the analyzer is specifically designed for gas-flushed packaging measurements. It is an electrochemical, fast response sensor having excellent zero and span stability, and with an operating measurement range of 0-100% Oxygen.
