Measuring the oxygen level with a Weld Purge Monitor® before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds that are metallurgically sound. It is important not to use “oxygen analyzers” or “oxygen safety monitors” as they are calibrated for accuracy only at ambient conditions.
The low cost, 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 parts per million (ppm) of oxygen.
Ron Sewell, Chairman for HFT® said: “We are extremely proud of the PurgEye® 100, our Flagship Product. This monitor is specifically designed for weld purging and is available at a competitive price, so that it will pay for itself in just a few welds.
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. With a clear, easy to read LCD screen, the PurgEye® 100 boasts a 24 mm high display with features such as a low battery icon as well as the low sensor icon. When the monitor is not in use, an automatic sleep mode activates to conserve battery life. The Weld Purge Monitor® was invented by HFT® in the 1970’s and with over 40 years of innovation, design and manufacturing experience, the company now has a Family of PurgEye® Weld Purge Monitors® to measure oxygen levels from atmospheric content (20.94%) down to 1 ppm (accurate to 10 ppm).
