Hydrogen sulfide analyzer AQMS550

monitoringlaboratoryfor the chemical industry

Product description: This product has the characteristics of high measurement accuracy, good reliability. fast response time, easy operation and wide application range. The analyzer supports manual calibration and automatic calibration, the calibration program can be set by the user, and supports remote control and remote upload. Real-time measurement data and instrument status parameters can be automatically transmitted and queried, which can facilitate relevant departments to grasp the air quality status in a timely and accurate manner. Technical principle: Catalytic oxidation method Catalytic oxidation method is the measurement of H2S molecules converted into SO2 molecules under high temperature conditions by a specific catalyst.UV fluorescence is based on molecular emission spectroscopy. SO2 molecules absorb ultraviolet (190nm ~ 230nm) energy to become excited state molecules. Excited molecules are unstable and release excess energy in the form of fluorescent photons when returning to the ground state. Advantages: •Measuring by ultraviolet fluorescence method, in line with EPA standards •Bidirectional RS232 port for remote control •Measurement range: 0 ~ 500ppb to 0 ~ 20ppm, user selectable •Digital state output instrument working parameters •Microprocessor realizes multi-function operation •Adaptive signal filtering technology optimizes response time •Software allows monitoring of test data during operation •With temperature compensation and pressure compensation •Continuous self-test with alarm function •Color screen display, touch screen operation •Light intensity attenuation self-test function •Large-capacity memory, automatically store historical data
