The portable Bühler O2 analyser model 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. There are
different puncturing devices available, depending on the type
of packaging.
The optional pressure gauge allows for comparison
measurements in vacuum packaging. With the electronic
correction when using the pressure gauge, no zero gas is
required for zero gas calibration. In addition, the zero point
may be corrected between N2 and CO2.
