Picarro-G2205 gas concentration analyzer
Product details
product overview
The Picarro G2205 gas concentration analyzer can accurately measure hydrogen fluoride (HF) and water vapor (H2O) in real-time, with a sensitivity of parts per trillion (ppt), and the drift generated for atmospheric science and air quality applications can be ignored. This analyzer is equipped with coating components in key gas pathways, which reduces the tendency of HF molecules to adhere to the surface of the gas pathway, thereby improving the measurement response time. This analyzer requires almost no consumables, therefore it has significant advantages of ease of use and lower purchase cost. This analyzer has a sturdy structure and is easy to transport.
Product Features
• Fast, continuous, and real-time measurement of HF
• Long term stability to meet low-frequency calibration requirements
• Small footprint, suitable for on-site or laboratory deployment, no need for consumables
• Equipped with water correction function, automatically reporting dry gas mole fraction
