Product Features
1) Ultra-low range design
The measurement range is less than 100mg/m3, which meets the national environmental protection ultra-low emission standard, and the resolution reaches 1mg/m3, which is suitable for ultra-low concentration flue gas detection and analysis.
2) High measurement accuracy
Based on the Ultraviolet Differential Absorption Spectroscopy (Ultraviolet Differential Absorption Spectroscopy) gas analysis technology, using a unique algorithm, long optical path multiple return gas chamber: the instrument has strong anti-interference ability, is less affected by external interference (temperature fluctuation, voltage fluctuation, etc.) and drift is lower; there is basically no cross-interference between multi-component gas measurements, and the measurement accuracy is high.
3) High degree of automation
Professional pre-processing scheme, with digital and analog output functions, high automation and low maintenance, can achieve real-time on-line monitoring without manual duty, greatly reducing the labor costs of enterprises.
