Picarro systems are trusted for their unmatched accuracy and reliability, thanks to advanced laser control and stable operating conditions. Our patented wavelength monitor (WLM) keeps the laser precisely tuned, ensuring highly accurate gas absorption measurements. At the same time, the system maintains tightly controlled temperature and pressure, with an insulated, actively heated sample chamber and automated pressure adjustments. This combination minimizes errors and ensures consistent, reliable results, offering a clear advantage over traditional methods like FTIR and GC systems.
