Huntingdon Fusion Techniques (HFT®) has launched an updated hand-held PurgEye® 200 Weld Purge Monitor®, now with PurgeNet™.
The portable device has an OLED (organic light emitting diode) display, which the company says will give brighter, clearer and sharper readings for viewing at greater distances than before and at wider angles.
The PurgEye 200 can operate from either long life rechargeable batteries or mains power.
Along with louder, pre-settable audio alarms for rising or falling oxygen (O2) levels, it comes complete with a faster response long life sensor and integral electro-mechanical pump to extract samples from a weld purge zone, in the event that there is insufficient flow rate or positive pressure to activate the sensor correctly.
Speaking about the new technology, Ron Sewell, HFT’s Chairman, said, “The PurgEye 200 is designed and manufactured with the HFT revolutionary PurgeNet, allowing networking to a range of accessories. Typically, one accessory allows direct interface to an Orbital Welder or any other automatic welding machine, so that the O2 level in the vicinity of the weld can be monitored and the welding machine can be switched on or off according to pre-set O2 levels. A second accessory is an audible and visual warning device that will signal externally when O2 levels are lower and higher than pre-set levels.”
The monitor reads down to one ppm and is IP65 rated, which means it can be used in very demanding areas where instruments are used on site, such as in desert or tropical conditions.
PurgeLog™ software also gives weld purging results to give quality control documents for each weld. The monitor also has the capability to switch between percentage O2 and parts per million shown on the display.
