Brief introduction: TH - 2001 nitrogen analyzer used the principle of high sensitive gas phase chemiluminescence, designed for continuous detection of atmospheric low NOX concentration. Nitrogen air automatic monitor is one of the high-tech products, it involves a number of technical, reflected light, machine, electricity and light chemical technology integrated application. NOX monitoring instrument adopts the advanced dual loop timeshare sampling pneumatic system, not only reduce the concentration of NO in the NOX and stable environment arising from the rapid change of measurement error, adding activated carbon gas cleaner to analysis instrument to provide zero air without NOX, therefore may go through the removal of NOX air sampling regularly zero, to monitor background signal to eliminate the zero drift. Features: 1. The gas circuit system of dual loop chemiluminescence nitrogen oxides analyzer adopts the advanced dual loop timeshare sampling pneumatic system, reduce the concentration of NO in the NO2 stable environment arising from the rapid change of measurement error, compared with the traditional similar dual channel at the same time, using only a reaction chamber and a PMT detectors, simplifies the system structure, improve the system reliability. 2. The instrument data acquisition through RS232 serial communication port, and other analyzer automatic monitoring network, collecting data through RS232 to stand, then center through the wired transmission way or GPRS remote data to be obtained, so that the rapid and timely grasp the air pollution situation of an area, has good temporal resolution. 3. Automatic range With the need of monitoring, if reading by more than 90% of the calibration range, will automatically switch to higher range, when reading return to 80% of the calibration, the instrument automatically return to the original range. 4. The temperature and pressure compensation According to the known gas concentration of analyzer is used to scale adjustment scale. 5. Digital filter analyzer adopts the advanced digital filter, the minimum mean square error of estimate as the criterion of response time and the best optimized signal-to-noise ratio, thus improve the SNR of the system. 6. Automatic calibration In order to ensure the precision of the instrument and achieve the best effect, in a certain cycle, calibration of instruments need to be zero and full. Son standing by applying the corresponding commands to complete the calibration instrument work, really realize the all-weather unattended, improve the degree of automation of the system. 7. Modern communication technology, remote monitoring system USES the RS232 interface implementation and son station system of data transmission, the son stands for automatic monitoring instrument, and the central station by GPRS MODEM or remote data transmission, constitutes a huge environmental monitoring information network, the analysis of pollution sources and the monitoring for environmental monitoring department provides fast and reliable data. 8. The instrument interface, full Chinese menu type is easy to operate. 9. Analyzer USES advanced KALMAN digital filter, the minimum mean square error of estimate as the criterion of response time and the best optimized signal-to-noise ratio, improve the SNR of the system.
