Online Differential UV Spectrometer is mainly used in the gas analysis industry, and the main detection occasions are: refineries, chemical plants, liquefied petroleum gas stations, boiler rooms, gas stations, paint rooms, metallurgy, mining, fire protection, environmental protection, etc. The main principle is: the sampling unit collects the flue gas or the gas to be measured on site, the pretreatment unit filters the dust, high temperature cooling, electric heating insulation, two-stage high-efficiency dehumidification, and controls the temperature and humidity of the gas to be measured, and the dust particles are controlled within a certain range to achieve the cleanliness required by the analyzer, and then sent to the gas analysis unit for detection and analysis, and the concentration of the gas to be measured is displayed in real time on the display screen, and the data signal is transmitted to the PLC or computer terminals, or it can be transmitted to the cloud server through wireless GPRS or network. The user then reads the data from the server, and global network monitoring and analysis can be realized. The whole process is automated and does not require human intervention.
Online differential ultraviolet spectrometer is used in various high temperature, high humidity or high dust occasions, and an automatic backflush system can be optionally equipped, otherwise the dust filter needs to be manually maintained and cleaned. The entire sampling pipeline has an electric heating and insulation function, which is beneficial to remove water vapor and prevent part of the gas from dissolving in condensed water to improve the accuracy of detection and analysis. The built-in two-stage high-efficiency condensation and dehumidification system can stably control the dew point of the gas at 4°C or 5°C, meeting the humidity control requirements of analytical instruments based on various principles.
