GS700 Series Portable Infrared Gas Leak Detector
CSA 
Hydrogen Compatible Description
The GS700 utilizes the latest infrared gas detection technology in a robust and reliable design. It provides intelligent data-logging functionality combined with optional GPS mapping to simplify data gathering and easily syncs with our cloud based Instrument Management System (IMS) to support reporting and compliance.
The natural gas discrimination feature quickly determines the source of gas leaks, whether it’s pipeline gas or naturally occurring biogas; saving valuable time and reducing detection related costs.
Ensuring compliance
Intelligent data-logging functionality together with optional GPS mapping simplifies data gathering. Our Instrument Management System improves fleet management by providing access to field usage reports, calibration history, investigation mapping and many other bespoke reports; making it easier for our customers to demonstrate compliance.
