Direct Optics PhoNO Nitrogen Dioxide Analyzer

The Global PhoNO is an innovative direct optics analyzer designed for precise measurement of nitrogen dioxide (NO2) concentrations in air, selectively separating NO2 from other nitrates to eliminate overestimation issues common in traditional methods. This compact device offers high conversion rates (>96%) of NO2 to NO with minimal variance (<0.1% per month), ensuring accurate, real-time monitoring independent of concentration, pressure, or temperature variations. Ideal for environmental monitoring, industrial emissions control, air quality assessment, and research applications, it features a long service life (>4 years) without memory effects, reducing maintenance costs and analyzer replacement needs. Advantages include cost-effective long-term operation (saving users >$20,000), simple installation without heaters or ozone scrubbers, and outputs for converter performance tracking. Compared to thermal converters, PhoNO provides selective high conversion at reduced pressures, linear response (r² = 0.99998), and repeatability. Drawbacks may include dependency on specific flow rates and pressures for optimal performance. Based on provided images, the unit appears new or in excellent condition, with no visible wear, and includes integrated components like tubing and power supply. No serial number or faceplate details are discernible from images; it seems self-contained without parent/child assets.
