For high quality welds
For TIG/GTAW welders, an accurate measuring instrument is the only way to be sure that the oxygen concentration is at the right level, before and during welding, in order to avoid oxidation and to reduce purge time/gas consumption. The welding process only begins when the oxygen level has been approved. This guarantees high-quality welds. To work with high precision, the oxygen indicator must have the following features:

• large measuring range
• high reliability and accuracy and fast response time
• self-diagnostic with alarm output
• pre-programmed calibration settings for inert gas and blends of 2%, 5% and 10% H2
