Sulfur oxide is a sulfuric anhydride, easily absorbed by the moist mucosal surfaces of the human body to form sulfuric acid and sulfurous acid, which have strong irritating effects on the eyes and respiratory mucosa. Specific symptoms include tearing, coughing, burning throat pain, conjunctival and respiratory tract stinging. When it comes into contact with human sweat, it can cause redness and swelling of the skin. Hydrogen fluoride, easily soluble in water, is also easily absorbed by the moist mucosal surfaces of the human body to form hydrofluoric acid. Its harm to the human body is similar to that of sulfur oxide, affecting the eyes and respiratory tract, but it is more harmful. Hydrofluoric acid is often used for etching glass, showing its extremely corrosive nature. If it comes into contact with human sweat, it forms hydrofluoric acid on the skin surface, which can penetrate the skin surface and permeate deep layers, causing ulcers and necrosis that are difficult to heal. If bone damage causes skeletal fluorosis, it cannot be reversed. The toxicity of hydrogen fluoride is even greater than that of sulfur oxide and sulfur hexafluoride.
Product Uses
The portable sulfur hexafluoride leak detector M321915 is very suitable for use by power supply departments, installation and maintenance units, and electric power testing research institutes. It is also suitable for SF6 high-voltage switch factories as supporting equipment for SF6 electrical equipment and export products, thereby improving the overall product grade.
Product Features
Small size: Lightweight, portable, with a handheld snake-shaped probe, and the connecting wire is more flexible.
High sensitivity: Super sensing, responds to trace halogen gases, can detect gas leaks of more than 3g per year.
Wide measurement range: The instrument can detect SF6 leakage within the leakage rate range of SF6 switch devices, with two ranges switchable.
High accuracy: The instrument uses advanced calibration methods to provide high-accuracy calibration curves, improving the credibility of SF6 leak detection results and the precision of quantitative leak detection.
Intuitive display, audible and visual alarm: Uses digital LCD with backlight display, providing a simple and intuitive effect. When sulfur hexafluoride is present, the instrument emits an audible and visual alarm.
Fast response speed, short recovery time: Adopts a new circuit structure, which speeds up the instrument's response and shortens recovery time, greatly facilitating on-site detection.
Rechargeable battery: Can be used for up to 5 hours, very suitable for field use.
