FPI AQMS-500 SO2 analyzer sulfur dioxide analyzer Ambient air quality monitoring system

Product catalog summary

Overview: The AQMS-500 Sulfur Dioxide Analyzer utilizes UV fluorescence technology, recognized by the US EPA as a federal reference method for measuring trace levels of SO₂. It is designed for ambient air quality monitoring with features that enhance usability and data accuracy.

Key Features:

Compliance with US EPA reference method.
Multiple output options including Ethernet and RS232.
User-friendly interface with a large display screen.
Continuous system diagnostics with alarm notifications.
Multi-tasking software for simultaneous operation and test variable viewing.
Temperature and pressure compensation for accurate readings.
Internal data logging capabilities ranging from 1 minute to 365 days.
Flow stability ensured by critical orifices.

Principle of Operation: The analyzer measures the intensity of fluorescence emitted by SO₂ in an air sample when exposed to UV light. The UV source lamp pulses to enhance optical intensity, allowing for lower detectable concentrations.

Interference Removal: A permeation scrubber removes aromatic hydrocarbons like xylene and naphthalene, while optical filtering reduces interference from high nitrogen oxides.

Data Storage and Analysis: Data can be retrieved via serial or Ethernet ports using PC client software, enabling predictive diagnostics and trend analysis.

Technical Specifications:

Standard Range: 0~100 ppb to 0~20 ppm (selectable).
Zero Noise: < 0.4 ppb (RMS).
Span Noise: < 2.5 ppb.
Lower Detectable Limit: < 0.5 ppb.
Zero Drift (24 hours): < 1 ppb.
Span Drift: < 1% F.S.
Response Time: < 80s (T90).
Precision: < 1%.
Linearity: < 1% F.S.
Sample Flow Rate: 650 cc/min ±10%.
Operating Temperature: 20~30°C (safe operation from 5~40°C).
Power Requirement: 100~240 VAC.
Dimensions and Weight: 178mm(H) x 432mm(W) x 597mm(D), 22kg.

AQMS-500 Sulfur Dioxide Analyzer FPI AQMS-500 sulfur dioxide (SO) analyzer applies UV fluorescence technology recommended by US EPA as federal reference method for trace level SO measurement. v Compliance with US EPA reference method v Various outputs include ethernet and RS232 v User friendly interface with large screen v Continuous system diagnosis with alarm v Multi-tasking software allows viewing test variables while operating v Temperature and pressure compensation v Internal data logging with 1 min to 365 day multiple averages v Critical orifices provide flow stability AQMS-500 measures the intensity of the characteristic fluorescence released by SO in an ambient air sample contained in the gas chamber when the air sample is irradiated by ultraviolet light passed through the chamber. UV source The pulsing of the UV source lamp serves to increase the optical intensity whereby a greater UV energy throughput and lower detectable concentration are realized. Removal of interferences The permeation scrubber acting as hydrocarbon kicker removes aromatic hydrocarbon such as xylene and naphthalene which causes interference. Optical filtering are employed to improve the rejection of interference from high nitrogen oxides. Data storage and analysis Stored data are easily retrievable through the serial or ethernet port via PC client software, allowing operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends.
