This measurement tool is especially useful in the food and beverage, pharmaceuticals and dairy industries where smooth, hygienic welds are crucial. The ‘optical oxygen measurement via fluorescence extinction’ method for welding technology is far superior to conventional methods. Many analysers from other providers use chemical sells, which depletes annually, which you need to replenish and calibrate.

This is not necessary with this product. Our method is also much more accurate. When using Argon, you want it to push out all oxygen – prevent oxidation. When measuring, oxygen level will be low already, as Argon is heavier gas, our analyser can detect even the smallest amount of oxygen traces.
