Introduction: ZR-7230 Portable Atomic Absorption Mercury Analyzer is a portable device for mercury on-site monitoring. The instrument adopts the principle of ultraviolet atomic absorption, which can directly perform real-time on-site rapid detection of mercury content in the air; The ethylene pipeline flue gas pre-treatment device avoids condensation of water vapor and adsorption of mercury vapor in pipelines, and conducts fast and accurate on-site detection of mercury in waste gas from fixed pollution sources, avoiding the lag between on-site sample collection and laboratory analysis, which leads to sample distortion and detection. result bias. This instrument can meet the measurement of mercury content in stationary source waste gas and ambient air, and can be widely used in the field detection of mercury in coal-fired power plants, waste incineration, chlor-alkali production, metal smelting and processing, cement production, crematoriums and other industries as well as ambient air On-site emergency monitoring of mercury in China. Features: 1. Light source: a low-pressure mercury lamp that can generate ultraviolet light with a single wavelength of 253.7 nm; 2. The gas circuit and pipeline are made of tetrafluoro and quartz glass to avoid test errors caused by pipeline adsorption; 3. Use the dual optical path differential method to eliminate background interference; 4. The calibration adopts the attached mercury calibration gas generator, which conforms to NIST standards; 5. The pretreatment of flue gas mercury refers to the standard of HJ543, and the attached flue gas mercury pretreatment device is used for pretreatment, and the measurement is carried out after reduction by chemical wet method; 6. Adopt automatic calibration method for temperature compensation to eliminate the error caused by temperature difference on test results; 7. The zero point calibration is carried out by automatic calibration or zero gas calibration; 8. Various measurement modes are available, flue gas mode (measurement accuracy: 0.1μg/m3) and measurement mode (measurement accuracy: 1μg/m3); 9. High-brightness 5.0-inch color screen, graphical display of Chinese characters, touch operation mode, wide temperature operation, clear visibility in outdoor sunlight; 10. AC power supply can be used to meet the requirements of continuous monitoring; a built-in Li-ion battery is also provided for power supply, which can be used continuously for more than 2 hours at 25 °C after full power; 11. The instrument shell is made of sheet metal, which is impact-resistant and anti-corrosion; 12. SD card data recording, real-time query detection data, standard Bluetooth printer, can print the flue gas parameter conversion report on site; 13. The instrument is small and portable, and the bare metal weight is ≤3kg; 14. The ZR-3062 integrated flue gas flow rate and humidity direct reading instrument can be selected to measure the working conditions, and the working condition information can also be manually input. Technical parameter: Sampling flow: 0.5L/min Host size: (length 310 × width 180 × height 180) mm Weight of the whole machine: ≤3.0kg (without battery) Power consumption: < 60W
