The New Hetek Flow Sampler

Portable, battery-powered
leak rate quantification.​

Flow Sampler Page

Portable, Intrinsically Safe Certified, Battery-Powered, Accurate

By utilizing a high-flow rate sampling method, we ensure 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.​
ACCURACY​ Sensor: ± 5% | Flow Rate: ±5% ​ Calculated Leak Rate: ±10%​
