Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, but not as this practicality
New restriction.
Specifically, as shown in FIG. 1 to 3, NO concentration detector concrete structure of the utility model based on spectrum includes：
Base 1 is detected, is provided with detection base on shock structure 2, shock structure 2 and is fixedly installed detection chambers 3, detected
Sample cell 4 is provided with chamber, the detection unit 7 being fixed on the outside of detection chambers is connected with positioned at sample cell head end, positioned at sample
QC tail end is connected with light source 8；
On sample cell and close on light source position and be provided with injection port 5, it is extraneous that the injection port extends to detection chambers；Sample cell
Go up and close on detection unit position and be provided with outlet 6；One is further fixedly arranged on the outside of detection chambers to be connected with detection unit
Mainboard 9, be provided with digital output interface 10, analog voltage output interface 11 and power interface 12 on mainboard 9.
In embodiment of the present utility model, it is preferred that SIO interfaces are used for the PC for connecting the external world.
After each device is connected in NO concentration detectors of the utility model based on spectrum, power supply is powered opens light simultaneously
Source, the detector needs the preheating of 15 minutes, then will need the gas detected from injection port is passed through sample cell, detection
Gas is flowed out by outlet, and light source passes through the gas that need to be detected to enter detection unit, and detection unit passes through different Spectral Properties
Property analyzes corresponding NO concentration in the gas, and the NO concentration detected can be exported by two ways：
One kind is analog voltage output, is exported by NOX interfaces or analog voltage output interface, analog voltage corresponds to
0ppm to 5000ppm；Another is numerical data output, is communicated by SIO interfaces or digital output interface with PC output.Mould
Automatic zero adjustment or span calibration can be realized by intending output and numeral output, and the calibration of numeral output is to send corresponding by PC
