Huntingdon Fusion Techniques (HFT®) has unveiled its latest, unique Weld Purge Monitor® which the company claims breaks “all technological boundaries in one instrument.”

The PurgEye® 600 has been designed and developed to read atmospheric levels of oxygen (O2) (20.94%) down to just one part per million (ppm) – or 0.0001%.

As well as its revolutionary monitoring ability, the gadget incorporates a whole host of modern features, including a life-time sensor which completely eliminates the need for calibration, as well as an internal sampling pump with gas filtration and leak tight fittings manufactured as standard.

Georgia Gascoyne, the UK-based enterprise’s CEO, explained the main properties of the new contemporary instrument, “The PurgEye® 600 incorporates the features and benefits of all the other Weld Purge Monitor designs in the HFT Family Range, but for the first time, this one instrument has a full range of measurement reading from atmospheric concentration (20.94%), down to 1ppm, accurate to 10ppm.”

Readings are indicated as either ppm or in percentage and control alarms can be individually pre-set by the operator to sound when O2 levels change.

The PurgEye 600 Weld Purge Monitor has been designed for the aerospace, pharmaceutical, semi-conductor, cryogenics and food and beverage industries where oxide free welds and traceability is essential.

HFT originally invented and manufactured its first O2 analysers and Weld Purge Monitors 40 years ago. The video (below) highlights the main features of HFT’s latest invention.
