Developed for weld purging, where data logging, alarms, and welder control are not necessarily required, it is small and lightweight. There are no knobs, switches, or controls, making this a simple plug-and-play monitor. A long-life sensor is used that has the capacity to measure oxygen down to 1 ppm accurately.
Effective weld purging is only achieved by making sure that oxygen is displaced from the purge zone prior to and during welding. Any residual oxygen can cause significant loss of corrosion resistance and a reduction in joint strength. It is therefore essential to seal the pipe on either side of the joint and maintain this seal throughout the process.
This monitor accurately measures from atmospheric level (20.94 percent) down to 100 parts per million (ppm), which accurately informs the welder when to commence welding.
These systems are manufactured for 6- to 96-inch pipe diameters (150-2,440 mm) and are equipped with a QuickFit coupling for the purge/inflation hose. The QuickFit coupling is fitted with an O-ring for gas-tight sealing.
