Based on single-beam and double-wavelength infrared principle :

In the principle of single beam and double wavelength, a measuring filter and a reference filter are imported into the optical path, so the band intercepted by the measuring filter is just within the infrared absorption wavelength of the measured component, and the band intercepted by the reference filter is outside the infrared absorption range of the measured component, so light intensity with measured gas affect and without measured gas affect can be calculated separately.

Based on infrared principles of gas-dependent filtration: 

In the gas correlation filtration principle, the optical filtration performance of the measurement filter and the reference filter are the same. In order to saturate the infrared absorption, the infrared spectrum of the specific substance has almost completely subsided, and the reference filter contains a gas filter tank with a high concentration of gas.

The principle of zirconia:

The measurement of oxygen is based on the principle of a zirconia battery. Inside the original, the measuring gas and the reference gas (ambient air) are separated by the zirconium metal film. According to the partial pressure of oxygen, the oxygen ions move on the membrane, forming a potential difference. The sampling pump provides a constant oxygen concentration for the measurement, so the energy consumed can be measured as the measured oxygen concentration.

Portable 9100 HIR gas analyzer  is a set of extraction type continuous measurement system. It can be used for the continuous emission monitoring of gas pollutants (e. g., CO, NO, NO2, N2O, NH3, CH4, HCI, SO2,) and the measurement of CO2, H2O and O2. It can also be used in continuous process control, desulfurization, denitration, catalyst, ammonia escape and other fields.

Portable 9100 HIR can be used in emission monitoring, pollution source flue gas monitoring, process monitoring and many other occasions. It can provide corresponding exhaust concentration monitoring for different types of fuel combustion, waste incineration, combustion process optimization and process management and control.

9100HIR measures the concentrations of up to 11 infrared gas components and evaluates them internally. Double-segment measuring range can be automatically switched, Visualisation, operating and data logging are realised via the delivered software

The unique characteristic is that adopt infrared measurement principle, with high temperature gas analysis in the  whole process.Instrument air supply is not necessary for its operation. The zero point setting is carried out with ambient air.

Adopting high temperature measurement method (without using refrigerator, avoid dissolution reaction, reduce the loss) heat and wet state analysis, the high temperature heating 185℃, water is gaseous, without water removal,directly analysis together with water content,can avoid the dissolution of the low concentration NO2, SO2, HCL, NH3 and other gases in the water removal process, especially suitable for the detection of low concentration NO2, SO2   after desulfurization denitration and ammonia escape,  optional minimum range SO2 is 0-50 mg/m3,  optional minimum range NH 3 is 0-10mg / m3;

Adopting the international advanced and mature original state sampling, original state analysis method. High temperature sampling, high temperature filtration, high temperature rapid analysis in the whole process, without gas drying, dilution, cooling and other pretreatment, direct analysis of samples, detection accuracy can reach 1% FS, and can achieve high precision measurement, measurement results are more real and reliable;
