The new InterPurge Model 772 Purge Monitor has been specifically designed for the welding industry. This unit enables welders to more accurately and economically recognize when the low oxygen levels needed to achieve good quality welds, is reached. The monitor uses a robust, long life, zirconium cell, features an integrated pump and has an inline filter. With a low measuring range of only 1ppm – 1000ppm (parts per million) of oxygen, this is the ideal tool to ensure high quality welds at the 50ppm (and lower) level that most QA/QC welding inspectors require today. Low maintenance due to long cell life and heavy duty design makes this the welders choice when welding high purity pipe for petrochemical, semi-conductor, nuclear, and dairy industries, just to name a few.
