Boreal Laser Gasfinder FC
GasFinderFC is a portable laser based gas detector that incorporates a fibre -optic port to which a variety of different measurement heads can be connected. These heads can enable stack monitoring, short and long open path monitoring or local point measurements.
GasFinderFC is therefore a very flexible analyzer that can now bring the advantages of laser based gas detection to many new applications.

Applications
Portable stack monitorMany industries are required to measure stack emissions of toxic gases periodically, but not continuously. Extractive, wet chemical methods currently used are slow, labor intensive and expensive. A single GasFinderFC can perform all a company’s stack monitoring requirements for a specific gas, quickly, easily and accurately. Portable multi-function gas detectorA single GasFinderFC combined with a complete set of measurement heads can enable a company to meet all their emissions monitoring needs for a single toxic gas, easily, reliably and cost effectively. |
Vehicle emissions monitorGasFinderFC can be configured to monitor CO and CO2 simultaneously, and combined with the short open path probe, can be set up across roads to monitor instantaneous emissions of these gases from vehicles passing through the beam. Pipeline leak detectorGasFinderFC can be configured with a customized probe and GPS system, and mounted in a vehicle or helicopter, to enable rapid, unambiguous detection and quantification of pipeline leaks. |
How GasFinderFC works
GasFinderFC houses a laser diode, drive electronics, and micro-computer subsystems. Fibre-optic cable carries the laser light to a separate transmitter/receiver head, which directs the beam along a measurement path to a reflector. The return light is collected on a photo-detector housed in the transceiver head and the photo current is carried to the GasFinderFC via coaxial cable for analysis.
The transceiver can be mounted in one of several different measurement head configurations. A fixed length probe is used for temporary or permanent stack monitoring. A short path configuration is used for paths to 20m, including cross stack/duct and cross road measurements. A long path transmitter head can be used for open path monitoring to 1km. Other custom probes are used for vehicle/airborne monitoring and point monitoring.
A portion of the laser beam is passed through a stable built-in reference cell to provide a continuous calibration update. The measure and reference signals are then compared to determine the actual concentration of gas along the measure path. This value is displayed on the back panel of the instrument. Serial and analog signals are also available. The serial signal contains self diagnostic data. The GasFinderFC also has a built in data logger than can store up to 10,000 readings.
