Weld purge monitor reads to 1 PPM
The PurgEye® 300 Nano Weld Purge Monitor™ from Huntingdon Fusion Techniques has been updated to read down to 1 PPM using a new-style zirconia sensor. It is suitable for weld purging of stainless, duplex, and superduplex steels, as well as titanium, zirconium, and nickel alloys.
In addition to measuring the oxygen levels when welding exotic alloys, the monitor can be used for weld purging of tube and pipe joints, either with manual or orbital welding techniques, and for ensuring the internal atmosphere in welding chambers, boxes, and enclosures is reduced to 10 PPM oxygen or less.
The small, lightweight instrument also can be used to check the quality of weld purge gases at source and to check for leaks in gas purge line
