Hetek High Flow Sampler 2.0
Walking Leak Surveys
The Hetek High Flow Sampler 2.0 is a portable, battery-powered instrument designed to quantify leak rates at components of natural gas infrastructure. Its high sampling flow captures gas escaping from a component, allowing the leak rate to be calculated directly from the measured sampling flow and methane concentration.
The instrument uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology and provides leak-rate measurements in CFM or LPM. Its touchscreen display and multiple measurement modes support leak quantification during field inspections.
Up to 10.9 CFM (310 LPM) maximum blower flow rate
0.03–220 LPM leak measurement range
6.8 kg instrument weight
Approximately 8 hours of battery runtime
