Huntingdon Fusion Techniques (HFT®), a weld purging products manufacturer, has created the PurgEye® 1000 Weld Purge Monitor, enabling operators to read weld purge gas levels from a distance for the first time.

The new device makes it possible to immediately read gas levels from the underside of the welding joint from up to 1,000 metres away.

The sensor is secured and fixed inside the purging system itself, which is connected to the measuring instrument via a data cable. The purge reading is then sent back to the instrument instantly allowing operators to accurately monitor, and therefore avoid oxidation, of weld zones.

Luke Keane, Distributor Support for the UK-based business, explained, “By using a zirconia sensor in a remote module placed at the purge gas exhaust, really close to the weld, it is possible to instantaneously receive actual oxygen (O2) readings down to 10 parts-per-million (ppm) up to 1,000 metres away.”

The instrument was designed to eliminate timely reading results as a consequence of attempting to attain stable readings in normal weld purge systems. By enabling the sensor to be placed directly next to the weld purging site, HFT have facilitated this without compromising the user’s safety.

This is the latest technological development in HFT’s Weld Purge Monitors® range.
