Advanced Instruments’ all-new GPR-1000 WP Pipe Weld Purge PPM Oxygen Analyzer is designed specifically for pipe welding applications, and features an innovative design and advanced long-life electrochemical oxygen sensor that provide highly reliable trace ppm oxygen readings in seconds.
Recommended oxygen levels are below 70 ppm in stainless steel welding, below 50 ppm in titanium welding, and below 10 ppm in the semiconductor industry. These measurements should be taken before welding commences to prevent oxidation, discoloration, and coking that result in substandard welds. The benefits of improving weld quality by reducing the rest oxygen to trace ppm levels are driving standards lower in other industries such as aerospace, pharmaceutical, dairy, brewery, chemical and food processing. The GPR-1000 WP is capable of measuring oxygen levels to meet standards in virtually all pipe welding applications.
The GPR-1000 is equipped with a built-in pump to draw the sample and a unique integral Bypass Valve. The Bypass Valve maintains the oxygen sensor at trace ppm oxygen levels, enabling the unit to come online in seconds.
There are optional accessories such as a stainless steel gap probe, in-line filter, 2-10m of tubing, and a carrying case, this unit is an all-in-one portable welding companion that will increase welder productivity, reduce purge gas waste, and enhance weld quality.
