Icad HONO-NO2 Analyzer series 210

The ICAD-HONO-200L is an advanced measurement system specifically designed to provide precise, high-time-resolution measurements of nitrous acid (HONO) and nitrogen dioxide (NO2). These are important air pollutants that play a significant role in the formation of secondary pollutants such as ozone and fine particulate matter. 

Direct HONO & NO2 Detection

• Iterative Cavity DOAS (ICAD) spectroscopy for high-resolution spectroscopic detection of HONO & NO2 from ~350 to 390nm. 
• No interferences from water, NOx, HCHO, or O2. 
• No sample drying required, eliminating the need for Nafion tubing. 
• Chemical and gas-free operation. 

Long-Term Stability and Robustness

• Insensitive to temperature fluctuations and vibrations. 
• Independent of absolute light source intensity. 
• No zero-point drift with integrated zero measurement. 

Easy Setup, Operation, and Low Maintenance

• No gas calibration needed, minimizing maintenance requirements. 
• Wi-Fi control via PC, tablet, or smartphone. 
• Versatile data communication protocols. 
• Compact 19” rack design. 
• Sustainable with long lifespan and low power consumption. 

Serie 210 New Features

• System health GUI and on-board diagnostics. 
• Easy span calibration adjustment via GUI. 
• Enhanced time resolution of 1 second. 
• Improved long-term stability. 

Graphical User Interface and On-Board Diagnosis

The user-friendly interface offers intuitive operation and rapid access to advanced features and data trends. The ICAD can be seamlessly controlled and monitored from any Wi-Fi enabled device without requiring additional software. A detailed system health report provides real-time status updates on crucial sensor parameters (e.g., gas flow, voltage, temperature) for efficient on-board troubleshooting.
