The equipment can automatically measure the SO3 concentration in the flue gas, suitable for long-term or short-term monitoring or comparison tests.

High temperature tracing and inert material lined sampling probes reduce measurement errors caused by sulfuric acid vapor condensation or adherence to lines.

The sampling unit, the preprocessing unit and the analysis unit adopt the modular design, which is convenient to carry and handle respectively.

The absorption rate of $O3 is improved by adopting the high-efficiency trapping technology of turbulence absorption.

High precision micro-flow control technology is adopted to ensure the accuracy of flow.

Automatic calibration according to the user-set cycle reduces the workload of on-site maintenance.

The device has functions such as real-time data recording and historical data query, and can query historical data curves.

Modular design, convenient on-site disassembly, handling and installation and commissioning.
