Weld purge monitor suitable for aerospace tube welding

(organic light emitting diode) display, which will give brighter, clearer and sharper readings for viewing at greater distances than before and at wider angles. These OLED displays are mainly symbol based, not text based, so menus are easily understandable, no matter what language the user speaks. This latest PurgEye 200 will operate either on batteries or mains power. Charging can also be carried out from an optional dock, and battery life will be longer than its predecessor. Along with louder, pre-settable audio alarms for rising or falling oxygen levels, the PurgEye 200 features a faster response long-life sensor and language options. The updated model has an integral electro mechanical pump so that it can be used to extract samples from a weld purge zone, where there is insufficient flow rate or positive pressure to activate the sensor correctly.

WHEN welding metals such as titanium, it is essential tomeasure the oxygen level before, during and after welding using a weld purge monitor (oxygen analyser). Weld purging expert Huntingdon Fusion Techniques (HFT) has launched an updated handheld PurgEye ® 200 weld purge monitor, now with PurgeNet™. Georgia Gascoyne, CEO for HFT, said, “PurgeNet allows networking to standard accessories. Typically, one accessory allows direct interface to an orbital welder or any other automatic welding machine, so that the oxygen level in the vicinity of the weld can be monitored and the welding machine can be switched on or off according to pre- set oxygen levels. A second accessory is a warning lamp that can signal when oxygen levels are low and high according to pre-set levels.” The portable PurgEye 200 is now manufactured with a new OLED

The PurgEye 200 weld purge monitor reads down to 1 ppm (very accurate to 10 ppm). The monitor is IP65 rated, which means it can be used in demanding areas where instruments are used on site, such as in desert or tropical conditions. PurgeLog™ software gives weld purging results to give quality control documents for each weld. The monitor also has the capability to switch between percentage oxygen and parts per million shown on the display.
