World Pipelines,
The new GPR-1000 WP Pipe Weld Purge PPM Oxygen Analyzer from Advanced Instruments is designed specifically for pipe welding applications. Featuring an innovative design and advanced long-life electrochemical oxygen sensor, this unit generates highly reliable trace ppm oxygen readings in seconds.
After using purge gas to remove oxygen from the weld area, professionals recommend welding only when oxygen levels have been reduced to less than 70 ppm in stainless steel welding, less than 50 ppm in titanium welding, and less than 10 ppm in the semiconductor industry to prevent oxidation, discoloration and coking. The GPR-1000 WP also offers the following features:
- User-friendly controls.
- Built-in pump to draw the sample.
- Unique integral bypass valve that isolates the sensor in a low oxygen atmosphere to bring the unit online in seconds.
- Rechargeable battery allows one week typical use on an overnight charge.
- No maintenance electrochemical oxygen sensor.
- Long-life sensor is replaced like a battery and unaffected by moisture or particulate matter.
- 24/7 use while charging with an AC adapter.
- Aluminum casing to withstand rigors of fieldwork.
