GMI Leak Surveyor

The GMI Leak Surveyor is designed for use in leak surveying of underground gas distribution pipes, including pinpointing, barholing and classifying. The instrument is a highly flexible, four button, portable gas detector which is designed to provide measurement of Parts Per Million (ppm), Lower Explosive Level (LEL)and Volume flammable gas for leak detection and general safety monitoring. In addition to using a fast speed of response semi-conductor sensor for ppm measurement, the instrument has a two speed pump and when the high speed is used together with the integral semi-conductor sensor, initial external leakage surveys can be performed in the vicinity of property or pipelines, enabling distribution leaks to be quickly found. The Leak Surveyor monitors continuously and is equipped with both audible and visual ‘Geiger’ alarm indications on the ppm range. FEATURES Integral Semi-conductor Sensor (Range 0-10,000 ppm), providing fast response leak detection. PPM, LEL and Volume flammable gas ranges for leak detection, general safety monitoring and barholing. Audible and visual ‘Geiger’ alarm indication on ppm range. Integral pump with pressure sensor for flow fail detection with sample path protected by hydrophobic filter. Rugged polypropylene case, sealed to IP54 rating, suitable for outdoor use. Simple button operation allowing access to all features. Rechargeable or alkaline battery options. Compatible with the full range of GMI accessories. Fully certified to international standards.
