Pipe weld purge PPM oxygen analyzer measures trace oxygen levels

Advanced Instruments Inc. has introduced the portable GPR-1000 WP weld purge PPM oxygen analyzer to measure trace PPM oxygen levels in seconds for pipe welding. The heavy-duty, rechargeable battery provides the unit with one week of typical use on a single overnight charge.

A built-in pump draws a sample from the purge chamber, allowing the integral bypass valve to maintain the electrochemical oxygen sensor at trace PPM oxygen levels. It is unaffected by moisture or particulate matter.
