In some high precision welding application, an inert gas such as argon is required to act as a shielding gas to create a mini oxygen free environment prior to welding. Southland Sensing takes a unique approach in its OMD-550 Welding Oxygen Analyzer by employing a Hybrid electrochemical oxygen sensor that can accurate measure oxygen from 50 ppm up to 20.9% with its built-in pump and no need for expensive sampling systems or finicky zirconia sensors.
Southland Sensing Ltd.’s line of welding oxygen analyzers offers a quantifiable element by accurately and reliably monitoring the welding atmosphere to make sure the oxygen content of the shielding gas is at an acceptable level.
