Measuring the oxygen level during Pipe Purging is crucial. Stainless steel has to be monitored down to at least 100 ppm, however alloys such as titanium and zirconium may need to be monitored down to as low as 10 ppm.

Pipe Purging Experts Huntingdon Fusion Techniques HFT®’s PurgEye® 200 Weld Purge Monitor® will ensure zero colour, non-oxidised welds are achieved every time, with accurate readings down to 10 ppm.

The PurgEye® 200 is a portable, hand held monitor, specifically developed and designed for use when welding titanium, zirconium, high specification stainless steel and nickel alloy joints, so that the user can produce metallurgically sound and oxide-free welds every time.

Luke Keane, Technical Sales Manager for HFT® said: “We’ve recently updated our Range of Weld Purge Monitors and most of which now include PurgeNet™, a networking device that allows accessories to be connected. These include an automatic welding machine interface so that the oxygen level in the vicinity of the weld can be continuously monitored and the welding machine can be switched on or off according to pre-set oxygen levels, an external audible and visual warning devices and a dew point monitor.”

The PurgEye® 200 has an OLED (organic light emitting diode) display, which will give bright, clear and sharp readings for viewing at distances and wide angles. These OLED displays are mainly symbol, rather than text based, making the menus internationally comprehensible.

This exceptionally advanced instrument is able to operate from rechargeable batteries or mains power. Along with loud, pre-settable audio alarms for rising or falling oxygen levels, the PurgEye® 200 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.

The PurgEye® 200 Weld Purge Monitor® reads down to 1 ppm (very accurate as far down as 10 ppm). It 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 is provided to record Weld Purging results and provides quality control documents for each weld.
