These types of instruments are extremely valuable. They provide a high degree of accuracy, and they have the mobility required for field use. These instruments both have a sampler and an analyzer. The sampler sucks in the leak source at a known flow rate and the on-board analyzer can determine the gas concentration. These two pieces of technology communicate together and can determine a value in standard cubic feet per minute, or scfm. Our software systems can automatically adjust the values to your preferred unit of measurement for reporting. We deploy these instruments as part of our Fugitive Emission Management Program.
