An early-warning gas leak detector, the Dräger Polytron® 8900 UGLD is built for outdoor industrial use. It uses ultrasonic technology to detect the sound of high-pressure gas leaks before gas accumulates, offering faster response compared to traditional methods. Leak detection is immediate, regardless of how the wind is blowing.
• Ultrasonic sensor technology – the early warning system for gas leaks
• A perfect complement to your gas detection system
• Delivers results that are easy to understand
• Can even detect gas leaks in loud industrial environments
• Robust design and fully-sealed sensor
For detecting high-pressure gas leaks in outdoor industrial process environments. Thanks to an ultrasonic acoustic sensor, it responds earlier than conventional gas detectors because it registers the sound of leaking gas instead of measuring the concentration of accumulated gas clouds. As gas escapes, leaks are immediately detected in the surrounding area, regardless of the wind direction. Environmental influences such as wind can delay or prevent a gas cloud from being detected by gas sensors. On the contrary, the DrägerPolytron 8900 UGLD is not affected by environmental factors and detects a high-pressure gas leak as soon asgas escapes. Effective early gas leak warnings can prevent unnecessary shutdowns, saving time and money.
