The Gassonic Surveyor is an ultrasonic gas leak detector. It is designed to detect pressurized gas leaks by sensing the
ultrasound generated by escaping pressurized gas. The detector is designed for use in harsh environments and extreme
weather conditions, making it ideal for detecting leaks in complex pipeline systems both onshore and offshore.
Gassonic Surveyor is developed, marketed and serviced by Gassonic A/S. Gassonic A/S is part of the General Monitors
family of companies. The Gassonic Surveyor and other selected Gassonic products are manufactured by General
Monitors, Ireland.

WoRKinG pRinciple
When gas leaks from a pressurized system, it emits a characteristic “hissing” sound. A part of this sound is high frequency
ultrasound, which can not be heard by humans.
As the detector senses ultrasonic noise, the Gassonic Surveyor does not have to be in contact with the leaking gas itself.
It will detect the gas leak instantly even if the gas is carried away by wind or diluted in the air. The Gassonic Surveyor can
be used in configurations with other detection methods.
