Jksf-3 air release value tester

Main functions and features
This instrument determines the air release values of hydraulic oil, turbine oil, and other petroleum products. Suitable for industries such as chemical, power, and petroleum. This instrument adopts LCD liquid crystal graphic scrolling display, human-machine dialogue interface, menu prompt input, which is convenient, intuitive, and easy to operate, making it an ideal substitute product for instruments.
This instrument uses MCS-51 microcontroller as the core, LCD liquid crystal graphic scrolling display, human-machine dialogue interface, and menu prompt input for controlling temperature, clock and other parameters. It applies high-precision sensing technology to convert analog signals into digital signals through A/D conversion, which are processed by a computer. The execution element adopts SSR technology to achieve high-precision control of water bath temperature, steam pressure temperature. The screen also provides prompts for clock and other parameters.
