When tubes and pipes in the Food and Beverage Industry are welded, it is vital that they are free from oxidation and discolouration. Welds that are not free from heavy oxidation may protrude into the pipe and create traps where product may build up over time and which could contaminate the product moving through the pipe. Measuring the oxygen level before, during and after welding therefore is vital to prevent these occurrences.

One way to measure the oxygen is to use a Weld Purge Monitor® and one of the leading instruments for this is the low cost PurgEye® 100 designed and manufactured by Weld Purging Experts Huntingdon Fusion Techniques HFT®. The PurgEye® 100 eliminates any guesswork about oxygen levels, providing accurate readings from atmospheric level down to 100 parts per million (ppm).

The PurgEye® 100 has a clear, easy to read LCD screen, with a 24 mm high display, which has a low battery icon. When the monitor is not in use, an automatic sleep mode activates to conserve battery life. 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.

A customer in the UK recently said: "We use your PurgEye® 100 Weld Purge Monitors twice a week on our five automatic dome welding machines for calibration purposes. I have to say that they are highly reliable and robust. If we need more or replacements we know where to go."

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 using the push button provided.

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).

Ron Sewell, Chairman for HFT® said: "All of Huntingdon Fusion Techniques HFT®'s Weld Purge Monitors® and Inflatable Tube, Pipe and Pipeline Weld Purging Systems are manufactured in the UK. We do not sacrifice on quality. We guarantee to help you achieve zero colour welds, time and time again."
