Mechanical dumbbell type paramagnetic principle, high detection accuracy, short preheating time, fast response speed, and good linearity;
Directly measuring the paramagnetic properties of oxygen with minimal background gas interference;
Preventive maintenance diagnosis with low maintenance volume;
Adopting a 7-inch color touch screen as the humancomputer interaction window, the display is beautiful, the content is rich, and the operation is simple;
Standard 3U chassis design, compatible with preprocessing system for various working conditions;
The surface of the window is covered with a piece of tempered glass to enhance the impact protection of the window;
Communication function: RS485/RS232 bidirectional communication is adopted, which can be switched through software selection and directly communicate with computers or other digital communication devices;
When the gas concentration deviates from the alarm value, an alarm will be triggered, and the alarm value can be set within the full range;
Isolated analog signal output, which can be set to 4-20mA or 0-20mA output mode through the menu.
Air separation high-purity oxygen analysis, laboratory gas content determination;
Automobile emissions and internal combustion engine testing;
Detect low-temperature gases and combustion gases;
Industrial gases generated at different stages of product purification process;
Instrument air supply, movable carts, and research laboratories in pneumatic systems;
Production of OLED, lithium-ion battery, high-intensity discharge (HID) lamps, and ceramic lamps;
Detection of oxygen concentration in high-pressure oxygen chambers, infant incubators, ventilators, anesthesia machines, etc;
Gas cylinder filling operation, inert atmosphere welding, pharmaceutical, nuclear industry, and chemical application fields.
