4 Operating principle
The device uses the integrated pump to suck-in a gas sample from the packaging to be inspected
and routes it to an O
2
and a CO
2
measuring cell.
The O
2
content in the aspirated gas mixture generates, in the chemical measuring cell, a weak
electrical voltage proportionate to the O
2
content. This voltage is measured and converted to form a
concentration value, which is then shown on the display.
The CO
2
measuring cell operates according to the infrared absorption principle.
Once the analysis is over, the O
2
and CO
2
concentration levels are stored with the date and time.
The internal memory is designed as a ring buffer (maximum number of stored measuring data: see
Technical data).
Everytime the memory is full, and a new measured value is stored, the oldest measured value is
overwritten. The assigned memory location is displayed by a segment bar at the top of the display.
The O
2
measuring cell of the Oxybaby
®
has a service life of approx. 1.5 to 2 years with an
O
2
content of 21 % per cent by volume. If the O
2
content is higher than 21 % per cent by volume,
the service life for the O
2
measuring cell is reduced (See Technical data for details).
The CO
2
measuring cell is non-wearing.
Oxybaby
®
is equipped with automatic pressure compensation, which serves to prevent any falsified
test results through changing ambient pressures or gas pressures in the packaging.
