Overview: AQMS-500 SO2 analyzer adopts ultraviolet fluorescence method and combines with advanced microprocessor technology. It provides accurate and reliable detection of SO2 at ppb~ppm level which meets the requirements of ambient gas monitoring and online monitoring of pollution source with dilution method. Measurement stability is greatly improved by using timed dark current measurement to compensate photo-multiplier drift and reference detector to calibrate the change of UV light intensity. With high-efficiency hydrocarbon remover and unique optical design the analyzer can effectively clear up inexactitude caused by interference. Features: 1.Measuring range: 0-500ppb to 0-20ppm,(optional). 2.Dual measurement range and auto set range. 3. Multiple functional operations by microprocessor. 4. Task software is allowed to monitor test data during operation. 5. Continuous self-checking with alarm function. 6. Self-check of light intensity attenuation. 7. Bidirectional RS-232 port for remote control. 8. Digital output working parameter. 9. Response time optimized by signal filter technology of self-adaptation. 10. Compensation function for temperature and pressure. 11. USB and Ethernet interface. 12. Colorful display and screen touch operation. 13. Large memory and history data saved automatically 14.On board storage for over 3 years of data Parameter: 1.Unit: ppb, ppm, μg/m3, mg/m3 2.Measurement range: 0~500ppb 3. Lower detection limit: ≤0.4ppb 4.Ports: Analog, Dihital, Rs232, RS485, RJ45, USB 5.Protocol: Modbus 6. Power Supply 200~240V, 50/60Hz, 300W
