Background:
Sulfur dioxide is a poisonous gas. When the concentration of sulfur dioxide in the air environment reaches 1 ppm, our bodies will feel oppressed and uncomfortable. When the concentration of carbon monoxide in the air is 200 ppm, symptoms such as mild headache, fatigue, dizziness, and nausea will only appear after 2 to 3 hours after inhalation. It can be seen that sulfur dioxide is very dangerous. The sulfur dioxide gas detector is a gas analyzer that can measure the concentration of sulfur dioxide gas. It can effectively monitor sulfur dioxide gas. Therefore, it has long been integrated into every aspect of our lives and is used in many industries.
Working principle:
The sulfur dioxide gas detector adopts the Electrochemical gas sensor detection method, which theoretically eliminates the measurement error of sulfur dioxide caused by changes in gas composition. Through experimental analysis, this method has greatly improved its selectivity, sensitivity, anti-interference ability, etc.
The device converts the gas concentration detected by the sulfur dioxide sensor into an electrical signal and transmits the data to the controller. The higher the detected gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the alarm, the alarm will Send out an alarm signal and start solenoid valves, exhaust fans and other external equipment to automatically eliminate hidden dangers. A fixed sulfur dioxide gas sensor needs to be used with a single-channel controller, and multiple devices can also be used with one or more hosts. It can be controlled at multiple points simultaneously through the Sulfur Dioxide Gas Sensor to effectively prevent the risk of explosion and poisoning.
The sulfur dioxide gas detector is a gas analyzer for toxic gas detection. It can detect common toxic gases quickly, reliably and with high accuracy. It uses plug-and-play smart sensors, allowing one instrument to flexibly detect Different gases provide effective personal safety protection for on-site workers.
Sulfur dioxide gas detector applications:
Sulfur dioxide is safe when added to food within a certain range, but excessive use will have serious consequences. If sulfite food additives are used excessively, they will seriously destroy the nutrients in the food and reduce the nutritional value of the food. If people consume excessive amounts of sulfites, they may experience adverse reactions such as headache, nausea, dizziness, and asthma. Long-term consumption of foods with excessive sulfites may cause nerve inflammation, bone marrow atrophy and other adverse symptoms.
In order to protect people's personal health, it is crucial to conduct food safety testing of sulfur dioxide in food. It is necessary to detect the sulfur dioxide content in food. The food sulfur dioxide detector can be used for rapid detection. The detection speed is fast and the detection efficiency is high. It makes up for the shortcomings of traditional detection methods. The instrument is small in size and easy to carry, and is suitable for the quantitative determination of sulfur dioxide in on-site gas samples, liquid samples and solid samples.
