ZR-5406 Ambient Air Online Monitor Calibration Device Introduction: The calibration device of ZR-5406 online ambient air monitor adopts the principle of dynamic addition method, which is used to calibrate the online monitoring gas analyzer for measuring SO2, NO2, NO and CO in atmospheric components, and conforms to the Calibration Specification for Online Monitoring Gas Analyzer for Ambient Air (Draft for Approval). The existing calibration method is a standard gas composed of reference materials (with some impurities) and nitrogen (not air), which is completely different from ambient air. There are also water and some interfering gases (oxygen, carbon dioxide, etc.) in the ambient air. The existence of these substances greatly increases the uncertainty of the measurement results. characteristic: 1. The principle of adding method is adopted, and the dynamic gas distribution method is used to continuously generate standard gas; 2. Combining the high purity gas cylinder with the permeation pipe system, different permeabilities can be obtained by adjusting the osmotic pressure difference. On the one hand, the concentration control is easier, and on the other hand, the standard long-term application (up to 3 years) is realized, which conforms to the long-term stability concept of the monitoring standard; 3. The device has organically integrated analytical methods, calibration technology and analytical instruments to achieve online, real-time, embedded and flat calibration, meeting the development requirements of the times; 4. The measurement results (measured parameter content) are only related to the instrument response value and standard addition amount, which greatly reduces the source of uncertainty and improves the level of calibration and measurement; 5. Realize the calibration mode of the matrix standard (taking the current ambient air as the background gas), eliminate the interference of the matrix, and improve the comparability of the measurement results by more than one order of magnitude; 6. There are more than 0%, 10%, 30%, 50% and 80% dosage ranges, covering low, medium and high range segments; 7. External CO real-time concentration monitoring sensor ensures the personal safety of users; 8. The self-developed proportional flowmeter is not affected by liquid water/steam, with high single point accuracy and low failure rate; 9. High precision cylinder temperature control system, wide temperature regulation range, fluctuation range ≤ 0.05 ℃; 10. The 7-inch industrial high brightness color touch screen is adopted, and the external USB interface and thermal printer are equipped. It supports data processing methods such as USB disk export and printing. Technical parameters: Mainframe working power supply: input AC (220 ± 22) V, (50 ± 1) Hz Host weight: about 25kg Air compressor weight: about 10kg Mainframe power consumption: ≤ 200W Power consumption of air compressor: ≤ 900W
