The MFA portable gas analyser introduced in 2002 by
Witt Gas Techniques Ltd, the Warrington, Cheshire based gas safety, control,
analyser and mixing equipment supplier is used for monitoring protective
atmosphere packaging (MAP). Used to measure 02 and CO2 levels in food
packaging, it is now supplied with a new, easy to clean, hygienic, robust
stainless steel casing.
This analyser requires only a 6 ml sample of gas from a package to monitor
the gas content. If the set limits in a package are exceeded an alarm
signal is given and the packaging line can be halted to avoid further
quality problems. Witt’s own ‘Logger’ software based
on Windows, stores the production data and can display them in Excel format
when connected to a PC. The data can then be stored for future reference.
In Holland, at one of Europe’s largest producers of mini cheese
packs, MFA is helping to keep the correct oxygen levels in the packs over
a programmed range. The MFA is used to continuously monitor the modified
atmosphere in a tube leading from the Witt gas mixers to the foil packaging.
The readings are recorded and stored using the Witt ‘Logger’
software. The MFA has reduced the sampling volume from 30 ml to approximately
6 ml. A volume saving of 80%. If the oxygen concentration deviates over
1%, the MFA gives an audio alarm and the line is automatically stopped.
The problem is then resolved.
The company’s QA auditing meets the standard of the BRC (British
Retailer Consortium). The Witt ‘Logger’ software records all
the important quality data for each of their production lines
4 models are available in the range depending on the application, including
for use in measuring O2, CO2, O2/CO2 and He in welding. All models can
operate in a temperature range between 0°C to 45°C and have two
alarm signals for minimum and maximum settings and being adjustable for
each gas. The measuring range is 0-100% with a +/- repeatability of 0,2%.
Options include the Witt ‘Logger’ Software, table printer
for instant documentation, audio-visual alarms, plug in for external signal
connections, fully automatic calibration for single gas use and a tamper
proof lockable door.
