Intelligent oxygen controllerOxygen controller model: HAD-ZKY-3

overview
HAD-ZKY-3Intelligent oxygen controllerThere are three major characteristics, Adopting a larger scale CI integrated circuit and dual four digit LED digital display, a control method combining fuzzy theory with traditional PID control is adopted Make the product have the advantages of long service life, more intuitive reading, and more accurate display. Secondly, the instrument measures the parameters and oxygen electrode parameters The instrument parameters and other aspects are controlled by computers And there are language prompts So: more accurate measurement, more precise control, easier operation, and more user-friendly. Thirdly, the circuit adopts unique shielding technology, which gives the product super strong anti-interference ability. Fourthly, it completely overcomes the faults of conversion switches and potentiometers that cause the instrument to not function properly. Even in extremely harsh electronic environments, it can still work stably for a long time Provide reliable guarantees for the safety production of enterprises.

Application scope
1: Thermal power plant Gas plant Monitoring of oxygen content in mixed water and gas during chemical and fertilizer production to avoid system explosions caused by excessive oxygen during the production process
2: For industrial and mining enterprises, the analysis of oxygen content in cabins, tunnels, coal mines, and chemical equipment containers is necessary to ensure the personal safety of workers
2: Regarding the exhaust of internal combustion engines Smoke duct Kiln Boiler Monitoring of oxygen content in thermal power plants and smelting gas to control coal combustion and save fuel effectively.
3: In the medical industry, it can be applied to ventilators, anesthesia machines, and hyperbaric oxygen chambers Measurement and control of oxygen in infant incubators and deep diving operations
4: For fruits and vegetables Modified atmosphere preservation and traditional Chinese medicine Dry Fruits. Grain, tobacco Monitoring and control of oxygen content during storage
5: Can be used for the growth of crops Measurement and monitoring of animal respiratory oxygen content, etc Everything requires 24-hour continuous discount monitor. Places and departments that control oxygen content
