Witt-Gasetechnik Oxybaby mobile gas analyser

Witt-Gasetechnik’s Oxybaby mobile gas analyser has been improved, with the aim of enhancing the precision and reliability along with the application range of quality testing for protective gas packaging.

The handheld unit developed for mobile sample analysis requires only a small amount of sample gas in the series standard entering production. Depending on the application, around 2 mL is adequate for determining the oxygen or carbon dioxide content.

This corresponds to about half of the gas required by previous versions of this widespread measuring instrument, the company says. Even the smallest packaging can therefore be monitored with a high degree of accuracy.

An optimised design and hose system as well as an improved interaction of the individual components makes this possible. According to the manufacturer, the modified structure will also increase reliability against failure and minimise service requirements.

The dual-pressure sensors installed provide a more accurate flow rate control and indicate the gas pressure in the packaging. The LED display has a white illuminated background making it easier for the user to read the measuring results, even at low ambient lighting.

There are three versions of Oxybaby with different equipment, for use primarily in the food and pharmaceutical industries. The sensor needle (protected when not used) is pushed into the packaging via a small sealing plate for the measurement. The evaluation is output automatically in just a few seconds.

The measuring range extends from 0 to 100% with a display accuracy of 0.1%. The measured values are saved.

The unit weighs around 600 g and is supplied in a protective case including batteries, spare parts, consumable material and accessories. It is available with options such as a barcode reader, Bluetooth capability and a can piercer for testing bottles and cans. Complete digital documentation and analysis of the measured results is also possible via optional software.
