FAQ
Q: What detection method is used?
A: The analyzer uses chemiluminescence—NO reacts with ozone to emit light proportional to concentration.
Q: Can it measure both NO and NO2?
A: Yes. NO is measured directly, while NO2 is converted to NO for total NOx quantification.
Q: Is it EPA compliant?
A: Yes, it meets U.S. EPA reference specifications for NOx monitoring.
Q: What communication interfaces are available?
A: RS232, RS485, Ethernet, 4–20 mA analog output, 12 digital I/O and relay outputs.
Q: What is the effective operating range?
A: The analyzer operates between 5–40°C and up to 95% RH (non-condensing).
Q: How is calibration performed?
A: It supports multi-point calibration using certified NO/NO2 gas standards.
