Product Description

The SO₂ Analyzer adopts ultraviolet fluorescence method and combines with advanced microprocessor technology. it provides accurate and reliable detection of SO₂ at ppb-ppm which meets the requirements of ambient gas monitoring and online monitoring of pollution source with dilution method.
The operation principle is based on ultraviolet fluorescence method. After absorbing the ultraviolet energy, SO₂ molecule is inspired to excited state and once it returns to ground state. It will release specific fluorescence. The intensity of fluorescence could realize quantitative measurement. Measurement stability is greatly improved by using timed dark current measurement to compensate photomultiplier drift and reference detector to calibrate the change of UV light intensity. With high-efficiency hydrocarbon remover and unique optical design the analyzer can effectively clear up inexactitude caused by interference.
This analyzer can completely control all functions and also provides online instruction for important work parameters. Real time auto compensation for temperature and pressure will be made during measurement.

Features:

• Measurement range 0~500ppb to 0~20ppm, user selectable;
• High efficiency hydrocarbon remover and unique optical design, strong anti-interference ability;
• Dark current compensation at fixed time, high stability;
• Self checking function of light intensity attenuation;
• Adaptive signal filtering technology to optimize response time;
• Large capacity memory, automatic storage of historical data.

Air Pollutant Parameters Analyzers:

 

Application:
Our SO2 gas analyzer is a type of air pollution analyzer used for atmospheric monitoring.

1. Public places: places with dense personnel, such as conference rooms, classrooms, exhibition halls, hospitals, shopping malls, bars, restaurants, airports, railway stations, entertainment halls, etc., sulfur dioxide gas detectors can be installed for ventilation control and environmental quality monitoring. To protect people's health.

2. Industry: SO2 gas analyzer can be widely used in industry, such as wastewater treatment, safety production, especially underground operation. It is very necessary to monitor the concentration of sulfur dioxide. Sulfur dioxide gas detectors can be widely used in industries related to sulfur dioxide, such as metal processing, pulp and paper making, cleaning and solvent extraction, and low-temperature cleaning.

3. Agriculture: sulfur dioxide is related to plant photosynthesis. Therefore, the SO2 gas analyzer can be widely used in agriculture. Proper concentration of air fertilizer can improve the yield of agricultural crops. When the concentration of sulfur dioxide is insufficient, gas fertilizer can be used, which is very helpful for the growth of vegetable plants and the improvement of vegetable yield.

4. Animal husbandry: air quality is related to the healthy growth of animals. If the air is turbid for a long time, the concentration of sulfur dioxide is high, and there is no ventilation, it will lead to animal disease or epidemic outbreak. Therefore, the installation of a SO2 gas analyzer in the farm can prevent the occurrence of animal epidemic.
