Picarro GasScouter G4302

Picarro GasScouter G4302

The Picarro GasScouter™ G4302 is a new-generation, light-weight, portable, battery-powered gas concentration analyzer designed for science on the move. It is a great mobile solution for real-time methane emission source attribution in the world’s most challenging, remote environments.

  • High-precision ppb measurements of CH4 and C2H6 concentrations 
  • Portable, lightweight (25 pounds), low power (35W) backpack case
  • Built-in rechargeable Li-ion battery for up to 6 hours of continuous operation 
  • Built-in WiFi for mobile operation with a tablet or smartphone in remote locations

Additional Information

The GasScouter analyzer operates in two different modes:

  1. Methane only mode to precisely measure trace levels of methane in the atmosphere, and
  2. Ethane/Methane mode to measure the ethane-to-methane ratio for determining the emission source

Ideal for efficient, exact identification and quantification of methane gas from biogenic and anthropogenic sources, especially in remote locations.

Our Advanced Monitoring team can provide client-tailored, on-site solutions for complex long- and short-term methane monitoring projects. We specialize in mass emission rate determination. Learn More.
