Combustion performance oxygen index tester for building materials wire and cable

JF-5Combustion performance oxygen index tester for building materials wire and cable

It is applicable to the determination of the combustion performance of plastics, rubber, electrical sleeving, fiber, foamed plastics, film, film, textile and other materials.
Advantages of the YZS-8A fully automatic oxygen index analyzer from Xunyu: 1 Full color touch screen control, simply set the oxygen concentration value on the touch screen, and the program will automatically adjust to the oxygen concentration balance and emit a beep sound prompt, eliminating the trouble of manually adjusting the oxygen concentration; 2. The step proportional valve is used to greatly improve the flow control accuracy. The closed-loop control is used to automatically adjust the oxygen concentration drift program to the target value during the test, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test, and greatly improves the test accuracy.
