Portable Gas Leak Detection Solution—MicroGuard™

The MicroGuard™ portable gas leak detector from ABB enables walking surveyors to identify leak locations while generating and sharing extensive digital reports within a few minutes. When compared to other technology, MicroGuard™ can detect, pinpoint, and map natural gas leaks more reliably and rapidly.

Find Leaks Fast

Leak surveyors do not have to use outdated, slow, and insensitive equipment anymore to identify gas leaks inside storage facilities, distribution pipelines, or anywhere inside the natural gas infrastructure.

This exclusive portable gas leak detection solution is powered by ABB’s LGR-ICOS™ ultrasensitive gas analyzer, a well-designed air-sampling wand, a sturdy phablet (large phone/tablet) with a high-brightness screen and GNNS capability, as well as proprietary software.

The advanced software of the MicroGuard™ offers a splendid graphical user interface, a computational platform for advanced analytics and geospatial mapping, while automatically generating investigation reports compatible with all leading geographic information systems.

Most specifically, MicroGuard™ can combine drive survey data (emissions indications), which is recorded and shared in the cloud by MobileGuard™, to allow walking surveyors to detect the sources within minutes.

The LGR-ICOS™ Advantages

Thanks to the exclusive benefits of the patented LGR-ICOS™ technology, gas analyzers from ABB are the preferred choice for customers.

Highest Precision and Sensitivity

The system integrates reliable, robust near-IR diode lasers with an optical cavity to achieve measurements with highest sensitivity and precision in a simple, rugged package.

Widest Dynamic Range

The MicroGuard™ portable gas leak detector performs direct measurement of absorption in an optical cavity instead of measuring only cavity decay time. It thus offers linear response over a considerably wider dynamic range compared to traditional TDLAS and CRDS techniques.

Best Performance

The system offers unmatched overall performance in each crucial metric (speed, accuracy, reliability, and linearity).

Field Serviceable/Minimal Downtime

The MicroGuard™ system has been developed for reliability and robustness, apart from performance. The overall simplicity of the system enables easy service, if it is needed.

Better Value

The performance of the analyzer is not affected by small shifts in optical alignment, thus facilitating the use of sub-systems and simpler components.

Comprehensive Platform

ABB exclusively offers an all-inclusive platform of solutions with the LGR-ICOS™ technology as the basis. These solutions have been designed to handle leak detection applications of any kind.
