AELAB AQMS-200 Dynamic Calibrator – Precision Gas Dilution & Ozone Calibration

The AELAB AQMS-200 Dynamic Calibrator utilizes two mass flow controllers to perform standard zero and span calibration with up to four gas sources. It ensures stable trace-level output and supports optional ozone generation, gas phase titration, and integrated photometric measurement for independent ozone calibration.

The system incorporates a high-performance linearized mass flow controller that provides stable and reproducible output for environmental monitoring stations, CEMS platforms, and laboratory calibration facilities.

⚙️ Design & Construction

The AQMS-200 integrates a precision dilution manifold with dual mass flow controllers engineered for high linearity and repeatability. The internal gas pathways are optimized for low-resistance flow distribution, supporting four calibration gas inputs and one diluent gas port. Optional modules include an ozone generator (0.1–6ppm) and a UV photometer for independent ozone measurement. The housing is designed for 220V AC operation with RS232, RS485, and Ethernet interfaces.

🔬 Working Principle / Testing Method

The calibrator performs dynamic dilution by regulating flow rates through two electronically controlled mass flow controllers. This enables accurate preparation of target gas concentrations for zero and span calibration. When equipped with the ozone generator, the system produces controlled ozone output with <1%/24h stability. The optional UV photometer quantifies ozone concentration using a precise absorption method, providing ppb-level accuracy, rapid response, and low drift characteristics.
