Measuring the oxygen level before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds. During stainless steel welding, the oxygen content must be purged down to a level as low as 100 ppm.
The hand held battery operated PurgEye® 100, designed and developed by Huntingdon Fusion Techniques HFT® is perfect for welding stainless steel, reading accurately from atmospheric oxygen level (20.94%), right down to 100 ppm (0.01%).
The PurgEye® 100 is IP65 rated and comes with leak-tight push buttons, auto calibration features, vacuum-sealed leak-tight probe assembly, wrist/neck strap, and tripod mount.
The extra long life sensor provides approximately 18 months life before it requires changing. A low sensor indicator will appear on the screen, warning that a new sensor is required. Once that icon appears, it provides the user with adequate time to obtain a new sensor, which can be fitted like changing a battery and the monitor can be re-calibrated easily by the user.
It is important not to use oxygen analysers or other oxygen safety monitors, they are calibrated for accuracy at ambient conditions and therefore not suitable for measuring purge levels at 0.01% as the PurgEye® 100 does.
