The AELAB AQMS-550 H₂S Analyzer utilizes UV fluorescence detection to measure hydrogen sulfide concentration with sub-ppb precision. Designed for continuous ambient and industrial air monitoring, it offers temperature and pressure compensation, large data storage, and multiple digital outputs—making it ideal for environmental agencies, oil and gas operations, and air quality research laboratories.
The AELAB AQMS-550 H₂S Analyzer provides precise measurement of hydrogen sulfide concentrations in ambient air using UV fluorescence technology. Designed for both environmental and industrial air quality monitoring, the system offers sub-ppb detection capability, making it suitable for compliance monitoring, workplace safety, and atmospheric research applications. Its stable optical system, automated diagnostics, and digital communication interfaces ensure reliable 24-hour operation in diverse field conditions.
The AQMS-550 features a compact, modular architecture enclosed in a corrosion-resistant housing suitable for laboratory and outdoor deployments. A color touchscreen interface allows intuitive configuration and real-time visualization of data. Integrated temperature and pressure compensation maintains accuracy under variable environmental conditions, while the low-power design minimizes operational costs and supports long-term monitoring in remote stations.
The AELAB AQMS-550 operates on the UV fluorescence detection principle. Hydrogen sulfide in the sampled air is first oxidized to sulfur dioxide, which emits fluorescence when excited by ultraviolet light. This emission is detected by a sensitive photomultiplier tube (PMT), and the resulting signal is converted into quantitative H₂S concentration values. The analyzer’s microprocessor automatically compensates for background noise and drift, ensuring high measurement precision and repeatability.
The AELAB AQMS-550 supports multiple data interfaces—RS232, RS485, and Ethernet—allowing seamless connection to air quality management systems, LIMS, or SCADA platforms. Its analog and digital outputs enable remote monitoring, process automation, and alarm-based safety responses. The large onboard memory facilitates long-term data storage with configurable averaging intervals for regulatory reporting.
The AQMS-550 is available in configurations optimized for industrial hygiene programs, environmental research, and fixed monitoring networks. Optional modules include extended data logging and cloud-based data integration. Its rugged design and long-term signal stability make it a dependable solution for both continuous emission and ambient air quality assessment.
The AELAB AQMS-550 H₂S Analyzer complies with ISO 9001 manufacturing standards and conforms to recognized environmental monitoring protocols. Each unit undergoes factory calibration, traceable verification, and functional testing to ensure measurement reliability. It is suitable for integration in EPA-equivalent or GLP-certified monitoring networks, ensuring regulatory accuracy and operational safety.
