The AELAB AQMS-400 Carbon Monoxide Analyzer utilizes Non-Dispersive Infrared (NDIR) technology to deliver accurate, real-time CO concentration measurements. Designed for laboratory, industrial, and environmental air quality applications, it provides long-term data logging, temperature and pressure compensation, and multi-protocol digital outputs for dependable CO monitoring.
The AELAB AQMS-400 Carbon Monoxide Analyzer is a precision air quality monitoring instrument that quantifies carbon monoxide (CO) concentrations using Non-Dispersive Infrared (NDIR) measurement technology. It is engineered for applications requiring continuous, accurate, and traceable CO data — including environmental monitoring stations, industrial emission control, and laboratory research facilities. The analyzer delivers high stability and linearity while maintaining low detection limits suitable for regulatory and scientific use.
The AELAB AQMS-400 features a 14-meter optical path enclosed within a precision-engineered housing to maximize light absorption accuracy. Its robust design complies with USEPA reference standards for carbon monoxide monitoring. The analyzer includes a large digital display, user-friendly interface, and a compact modular design for ease of operation and integration into air quality management systems. Built-in diagnostics continuously evaluate performance, with alarm outputs for system alerts and calibration requirements.
The AQMS-400 measures carbon monoxide via NDIR absorption. Infrared radiation passes through the sample gas along a 14 m optical path. Carbon monoxide molecules absorb specific infrared wavelengths, and the degree of absorption is directly proportional to CO concentration. The analyzer’s internal sensors compensate for temperature and pressure fluctuations, ensuring accurate and reproducible readings. This approach enables trace-level detection while maintaining long-term measurement stability in varying ambient conditions.
The AELAB AQMS-400 provides full communication flexibility with RS232, RS485, and Ethernet outputs, ensuring compatibility with LIMS, SCADA, and environmental data acquisition systems. Analog outputs allow connection to industrial controllers or data loggers. Internal storage supports long-term averaging and trace archiving, simplifying trend analysis and compliance reporting. Continuous self-check and alarm functions enhance data integrity and operational uptime.
The AQMS-400 represents AELAB’s expertise in analytical gas instrumentation, combining precision NDIR technology with robust hardware and intelligent software design. Its long optical path ensures reliable readings even at low concentrations, while modular configuration options support customization for educational, regulatory, or research environments. Designed for long-term field use, it remains stable under continuous operation with minimal maintenance requirements.
The AELAB AQMS-400 Carbon Monoxide Analyzer adheres to USEPA reference methods and ISO 9001 quality standards. Each instrument undergoes full factory calibration and testing to verify performance stability, response time, and drift parameters. The system supports traceable gas calibration routines, ensuring regulatory compliance for industrial and environmental monitoring programs. AELAB guarantees precision operation through certified quality control and long-term component reliability.
