Low Cost 1 PPM Weld Purge Monitor®
For many years, oxygen monitors and gas analysers have been used for
weld purging. These instruments have been designed and calibrated for
accuracy at atmospheric oxygen level, but not for weld purging where
accuracy is required when reading much lower oxygen levels.
With their scientific background, Huntingdon
Fusion Techniques HFT® have designed and
manufactured the PurgEye® 300 Nano, the
World’s first and only low cost, no frills, Weld
Purge Monitor® that measures accurately
down to 10 parts per million (ppm) on a large
alpha numeric display.
Ron Sewell, Chairman for HFT® said: “The PurgEye®
300 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.”

“A unique long life sensor is used, that has the
capacity to measure oxygen down to 1 ppm with very
high accuracy down to 10 ppm. The Nano avoids the
disadvantages of monitors with ‘wet cell’ technology
that have to be regularly calibrated and have sensors
replaced.”
With its ‘leak tight’ connectors for weld purge hoses,
the PurgEye® 300 Nano can be used with free flow
from the exhaust of a purging system, or with an
optional accessory hand pump and gas sampling
probe that can take readings via a joint gap.
