Low cost weld purge monitoring down to 10 ppm

For many years, oxygen monitors and gas analyzers have been used for weld purging. They are specifically designed and calibrated for accuracy at atmospheric oxygen level but not for weld purging where accuracy is required when reading much lower oxygen levels. 

Using the latest scientific knowledge and innovation, Huntingdon Fusion Techniques HFT® have designed and manufactured the PurgEye® Nano, the World’s first and only low cost, no frills, Weld Purge Monitor® that measures accurately down to 10 parts per million (ppm). 

Ron Sewell, Chairman for HFT® said: “A Weld Purge Monitor® is essential to monitor oxygen levels when welding metals such as stainless steels, titanium and nickel alloys where a high quality, non-oxidized, zero color weld is required. The PurgEye® Nano has been developed for weld purging where data logging, alarms and welder control are not necessarily required. It is small, lightweight and inexpensive. There are no knobs, no switches, no controls, making this a really simple, ‘plug and play’ monitor.” 

With its leak tight connectors for weld purge hoses, the PurgEye® Nano can be used with optional accessory hand pump and gas sampling probe. The monitor can be used to check purge gas quality from the main source and at the exhaust end of a purging system as well as to find air leaks in purging hose connections anywhere in a system.  

HFT® has a Family Range of PurgEye® Weld Purge Monitors® for every application. The range includes hand held, battery operated monitors and mains powered monitors, which can read oxygen levels from atmospheric concentrate, right down to 1 ppm.
