The Hi-Flow Sampler is a portable, intrinsically safe, battery-powered instrument with the ability to accurately measure leak rates of all natural gas components. Whether you’re managing a leak detection and repair program or active in greenhouse gas trading, the Hi Flow Sampler allows an accurate emission or leak rate to be made in less than one tenth the time required to perform an enclosure measurement. This is accomplished by sampling at a large flow rate (between 0.5 and 10.5 cfm) to completely capture all the gas leaking from the component. The instrument measures the flow rate of the sampling stream and the natural gas concentration and then calculates the actual leak rate in real time, which is viewed on the LCD. Other features include data logging, auto calibration, two rechargeable (5 hour) batteries, background measurement to ensure complete sample capture, sampling accessories, and a backpack for mobility.
