The New Hetek
Flow Sampler

Portable, battery-powered
leak rate quantification.

Portable, Intrinsically Safe Certified,
Battery-Powered, Accurate

The Hetek Flow Sampler is a portable, battery-powered, and intrinsically safe certified device, making it ideal for use in both expansive industrial facilities and confined spaces. With its compact size and lightweight construction, the Flow Sampler never compromises functionality, ensuring accurate and reliable methane quantification even in the most challenging environments. By utilizing a high-flow rate sampling method, the Hetek Flow Sampler ensures the complete capture of all gases escaping from the component. This technique allows for precise measurement of both the flow rate of the sample and the concentration of gas within it. 

The result is an exact calculation of the leak rate, expressed in cubic feet per minute (CFM) or liters per minute (LPM), enabling effective monitoring and control of emissions to safeguard both the environment and industry compliance.
