ZR-7220 Portable Methane Non-Methane Total Hydrocarbon Analyzer
Introduction: ZR-7220 Portable Methane-Non-Methane Total Hydrocarbon Analyzer (Type A) is a portable device for monitoring non-methane total hydrocarbons. It adopts the principle of chromatographic column separation-hydrogen flame ionization detector for detection. The technical route of systematic and whole-process heat tracing avoids the occurrence of particulate matter and condensed water entering the instrument, and conducts rapid and accurate on-site detection of "total hydrocarbons, methane and non-methane total hydrocarbons in exhaust gas in ambient air and stationary pollution sources" to avoid on-site sample collection. The lag to laboratory analysis leads to sample distortion causing deviations in monitoring results. This instrument can measure NMHC in exhaust gas under the conditions of high humidity and particulate matter pollution during fixed source organized emission. It is widely used in organic chemical plants, surface coating industry, printing and dyeing industry, furniture manufacturing industry, automobile manufacturing industry , pharmaceutical industry and other industries on-site monitoring of total non-methane hydrocarbons, monitoring of total non-methane hydrocarbons in the atmospheric environment. Features: 1. The preheating time is short, the preheating can be completed within 15~20min, and the on-site rapid detection; 2. The analysis period is short, the analysis period is 60s, the detection frequency is increased, and the pollution changes can be quickly captured; 3. Four-way electronic pressure controller, the control resolution reaches 0.01psi, temperature compensation, and stable control; 4. Backflush gas path, effectively avoid data errors caused by the participation of interfering components; 5. The whole process is heated at high temperature, the inner wall of the sampling tube is silanized, and there is no adsorption; 6. The detection limit is low, and it can meet the rapid detection of non-methane total hydrocarbons in ambient air and stationary sources at the same time; 7. Equipped with large-capacity lithium battery, which can support on-site detection time ≥5h (with sampling tube preheating ≥3h); 8. Imported solid hydrogen storage bottle, with large hydrogen storage capacity, long service life and safe use; 9. The inlet of the host has a built-in filter element, which can effectively filter particulate matter and prevent it from entering the host and affecting the test; 10. Equipped with column oven module, FID detector module and electrical control module with independent intellectual property rights, key components are equipped with constant temperature and shock absorption device to eliminate temperature drift, and the measurement results are stable and reliable; 11. Built-in calibration points of different concentrations, select the required calibration concentration according to the different spans of high and low concentration values of NMHC test; 12. The test data can print the data receipt, export the test spectrum, and automatically calculate the emission rate in combination with the working condition information; 13. Dynamic display of instrument status, which is convenient for users to grasp the working conditions of the instrument; 14. Imported diaphragm valve is adopted to avoid test error caused by dead volume and gas leakage, and the service life is longer; 15. Real-time query test data, equipped with a Bluetooth printer, can print on-site according to the selected test results; 16. Optional ZR-3062 integrated flue gas flow rate and humidity direct reading instrument for working condition measurement, or manual input of working condition information; 17. Optional PAD Communicator is convenient for users to obtain and observe data. Technical parameter: Battery: 25.9V/19.2Ah (full power can work for at least 3h) Host size: (415×270×300)mm Power consumption: ≤400W Host weight: ≤13.6kg (host)
