Stack emissions gas analyzer SO2 NO,NO2,O2,NH3,CO,CO2,Cl2,O3,H2S,HCl,CH3I
The analyzer is based on ultraviolet differential absorption spectroscopy (DOAS) and chemometrics algorithm (PLS). It can measure SO2, NO, NO2, O2, NH3, CO, CO2, Cl2, O3, H2S, HCl, CH3I and other gas concentrations. It has the characteristics of high measurement accuracy, strong reliability, low operating cost, fast response time, large span, and wide application range.
Products are widely used in tail gas emission monitoring and process control of coal-fired power plants, garbage power plants, cement plants, glass plants, lime plants, ceramics plants, sintering, coke ovens, desulfurization processes, and denitration processes.
Features
- Portable case design. The portable flue gas analyzer consists of a gaseous pollutant monitoring unit, a monitoring unit for flue gas parameters (oxygen content, etc.), and a data acquisition and processing unit. The instrument structure mainly includes a flue gas sampler and a transmission pipeline, Flue gas pre-processor, analyzer; equipped with touch Android display, large data storage, multi-port output and real-time monitoring data printer
- Low detection limit and small drift using ultraviolet differential absorption spectroscopy technology and chemometric algorithm.
- The instrument measures the volume concentration of SO2, NO, NO2, O2, NH3, CO, CO2, Cl2, O3, H2S, HCl, and CH3I in the sample gas.
- NOx and NO2 can be directly measured to obtain NOx, and NO2→ NO converter is not required.
- Not affected by particles and moisture
- No optical moving parts are highly reliable, and the on-site vibration has no effect on the measurement
- Increase the over-range limit enable function to ensure the measurement accuracy within the range, and the over-range can be measured to provide a reference for the measured value.
- Equipped with a user-calibrated intelligent determination of ventilation concentration to prevent misuse by the user and make the instrument unusable.
- Fast Analyze the data in one minute
- Automatically samples, analyzes, detects, and measures quickly, using no consumables.
- Easy to operate and can be operated after the personnel are trained on site.
- Suitable for continuous monitoring at the industrial site and sampling and analysis of airbags in the laboratory.
- English software operating systems are available.
- The instrument software is powerful, with functions such as automatic data storage, query, deletion, and USB export. The history data storage site name can be customized), and the measurement data storage interval can be customized.
- Built-in lithium battery, soft-start power switch, intelligent battery power management, low battery alarm.
- Built-in imported sampling air pump, with sampling flow display and sampling flow can be set, the state of the sampling pump can be dynamically tuned to meet on-site testing under various pressure conditions.
- It can be connected with an external pretreatment device to increase on-site measurement accuracy and protect the instrument.
- RS-485 digital output interface
- Modular product design, remote software upgrade.
