ARGWELD® Purge Monitors

PurgEye 100 purge monitor 


The all-new PurgEye™ 100 Purge Monitors are the most advanced purge monitor of its kind from the makers of the best-selling MK V Purge Monitor. This new unit, like the earlier MK V models, is small, portable, easy to use and reliable. It will monitor O2 levels down to 0.01% (100 PPM) with a high degree of accuracy and comes complete with a stainless steel probe, 6 ft rubber tubing, aspirator bulb and carrying strap in a custom foam-lined case.

It can be used in a continuous monitoring mode by connecting the tubing to an exhaust port of a purging device or enclosure and allowing the gas to flow freely over the sensor, or it can be used in a sampling mode by inserting the stainless steel probe into the area being purged or to an exhaust and using the aspirator bulb to initiate the flow across the sensor.

The Argweld® product line has led the industry in cutting edge weld purging technology for over 30 years, and continues the tradition with the new PurgEye™ 100 Purge Monitors unit that offers even greater accuracy and unmatched features.

The Argweld® PurgEye™ 100 is specifically designed and built for welding applications to give accurate readings at the low O2 levels required for weld purging. In fact, the PurgEye™ 100 is significantly more accurate than any purge monitor of its kind. Don’t risk your welds with inferior purge monitors or O2 sensors and monitors designed for confined space or medical applications that are inaccurate at lower O2 levels.

Accurately measuring down to 10 ppm

PurgEye 200 Purge Monitors

Now with an OLED display, the PurgEye ® 200 Weld Purge Monitor gives sharper, brighter and clearer readings for viewing at longer distances than before. The OLED display is mainly symbol based, which means the menus are easily understandable regardless of which languages the user speaks.

PurgEye 1000 Remote

Long Distance Weld Purge Monitor
PurgEye 1000 Weld Purge MonitorMeasuring accurately down to 10 ppm. With an internal electro-mechanical pump, battery or power driven with .PurgEye® 1000 Remote Sensing Head can be fitted onto a mechanical or inflatable purging system, directly at the weld location and will measure oxygen level in the purge gas and transmit the information electronically to the monitor up to 1 km away. With this capability, operators can obtain an instantaneous and correct weld purge reading no matter how far they are from the weld and be certain that the joint will not be adversely affected by oxidation.

Measuring Down to 1 ppm!
