Press Release Summary:

July 10, 2014 - Used to qualify purge gas cylinders, protect welds from atmospheric contamination, and reduce purge gas waste, GPR-1000 CW combines electrochemical PPM oxygen sensor, electronics, and sample system in one metal enclosure. Maintenance-free sensor tracks oxygen levels from air (20.9%) to <100 ppm in minutes. Unaffected by changes in flow rate, particulates, moisture, position, or vibration, analyzer has 10 sec response time and single-point field calibration with air or span gas.

Portable PPM Oxygen Analyzer Increase Weld Quality and Productivity

Press release date: July 6, 2014

An advanced electrochemical PPM oxygen sensor combined with proven state of the art electronics and a unique sample system in a rugged metal enclosure enables the GPR-1000 CW Portable PPM Oxygen Analyzer to qualify purge gas cylinders, protect welds from atmospheric contamination, reduce purge gas waste and increase user productivity.

This advanced electrochemical sensor requires no maintenance and tracks oxygen levels from air (20.9%) to below 100 PPM in minutes in addition to:
Superior stability and sensitivity at PPM oxygen levels
Specific to oxygen assuring accuracy and linearity
Fast 10 second response time
Single point field calibration with air or span gas
Unaffected by changes in flow rate, particulates, moisture, position or vibration.
Easy and inexpensive to replace at the end of its extended 24 month service life

Compensating for changes in temperature eliminate environmental influences and assure the reliability and accuracy of oxygen readings.

Productivity and ROI are significantly increased by an integral sample pump that draws sample through an optional probe and the sample isolation valve that maintains the atmosphere surrounding the sensor at PPM oxygen levels when not in use and switching between sample points, thereby reducing the recovery time (downtime) to seconds.
