Buehler BA 4000 Oxygen Headspace Analysis

The portable Bühler O2 analyser BA 4000 Inj. is a special unit for determining oxygen in low gas volumes. This analyser is a modification of the BA 4000, primarily used in the food industry to analyse small residual amounts in modified atmosphere packaging, bottles, or tins. The O2 content in insulating glass panes can also be determined.
We offer two versions:
The BA 4000 Inj. GV is used for volumes > 35 ml.
The BA 4000 Inj. KV is used for gas volumes < 35 ml. This analyser is operated by an external vacuum pump. We offer different puncturing devices suitable for the specific type of packaging. The optional pressure gauge allows for comparison measurements in vacuum packaging. The electronic correction when using the pressure gauge, no zero gas is required for zero gas calibration. It further allows correcting the zero point between N2 and CO2.
