InterPurge® offers a variety of welding purge monitors, though we only offer units that display in ppm (parts per milion) as well as give accurate readings down to a minimum of either 100 ppm, 10 ppm or even 1 ppm. This is required as high quality welding is usually performed at levels below 70 ppm, many below 50 ppm. Many web sites as well as welding suppliers offer welding purge monitors that can only display to 0.01% or 100 ppm rest oxygen: This is misleading, as these units will not offer the display resolution nor the accuracy needed to guarantee a quality weld. We also offer the InterPurge® 772 as a rental or a rent to own option, so convince yourself before purchasing.

We also calibrate and repair what we sell. Please inquire for a quote for repair and calibration services.
