Oxygen analysis down to ppm
Gas technology manufacturer Witt has
unveiled a new development that can
measure trace oxygen levels. The gas
analyser PA 7.0 enables reliable analysis
in the ppm (parts per million) range.
In many industrial processes, even the
smallest amounts of oxygen can cause
major problems, such as undesired
oxidation. A highly sensitive zirconium
cell, available as an option, allows
the PA gas analyser to detect trace
quantities of oxygen in gaseous media.
This extends the PA product series
into a new area of gas analysis. While
the classic PA with chemical sensor
measures in increments of 0.1 per cent,
the new zirconium version detects in
the ppm range. The accuracy of the
measurements is ±5 per cent relative to
the measured value.
All measured values are stored, and can
be downloaded via a standard interface
for further processing. Weighing just
under 6kg, the PA is only 186 x 285 x
270mm in size, and is protected by a
stainless steel housing.
The new PA version is part of an exten-
sive product portfolio comprising
mobile and stationary systems for
gas applications, especially in food
packaging, medical applications,
metalworking and glass production, as
well as in industrial processes requiring
a high degree of precision.
