Huntington Fusion Purge Monitor | PurgEye™100

Supplier: SMENCO

The global leaders in weld purge monitoring, Huntingdon Fusion Techniques, has released its latest PurgEye™100 monitor with Auto Calibration to maintain its class-leading reputation.

Price Guide: POA

With tungsten inert gas welding (TIG) of important joints in stainless steels and other reactive metals, it is essential to know that the oxygen content in the welding volume has been reduced to a low level to allow a weld start with minimal risk of oxidation.

Welding can begin once the desired oxygen level is achieved, so use a PurgEye™ Weld Purge Monitor™ everytime for a guaranteed accurate reading.

The system can be used with any pipe welding system, weld purging chamber or weld purging enclosure and is shipped in a robust storage case to maintain the instrument in good condition together with all accessories.

SMENCO, one of Australia's leading distributors of welding equipment and welding technology, is the national distributor for Huntingdon Fusion and has recently announced its appointment as national distributor for Bohler Welding, T-Put welding consumables for pipeline construction and DWT pipe preparation and pipe cutting equipment.

Anthony England, Managing Director SMENCO Pty Ltd, said the new PurgEye™100 monitor would improve welding efficiencies in the pipeline industry and was very competitively priced.

The innovative Push Button Auto Calibration facility on the front ensures oxygen readings are as accurate as possible every time you weld. At the touch of a button you can calibrate to the atmospheric level of 20.94%. SMENCO can supply a calibration certificate when required.

The sensor is easy to replace and self calibrate using the advanced calibration features of the PurgEye™100 and the specially written algorithm that provides extreme accuracy at 0.1% which is especially important for weld purging.

The monitor can be used as a continuously reading instrument with free flow of the purge exhaust gas across the sensor or as a sampling instrument with the hand vacuum pump and stainless steel probe assembly extracting samples from the purged volume, as and when desired.

Other first-time user friendly features of the new Auto Calibration model is the 'low sensor level signal' which gives the operator plenty of time to fit and calibrate a new sensor and the 'low battery indicator' which appears on the screen as a warning. Other key features of the PurgEye™ Weld Purge Monitor™ include:

Automatic Sleep Mode
When the monitor registers more than 20% oxygen for periods longer than one hour, it will automatically switch off to conserve sensor and battery life.

Extra Range
The PurgEye™ 100 Weld Purge Monitor™ indicates oxygen levels down to 100 parts per million (PPM) 0.01% and measures accurately down to 0.1%.

Enlarged Screen
The new enlarged screen uses 24 mm size digits for easy viewing at longer distances from the workstation. These digits are 40% larger than other models.

Tripod Mount
With mounting the instrument on a tripod, easy visual observation is provided so you can see the PurgEye™ 100 Weld Purge Monitor™ from any part of the working space. A range of tripods or other fixing devices is available.
