天狮娱乐Wjhc-5 intelligent full automatic touch screen controlled oxygen index tester

天狮娱乐1、 Advantages of wjhc-5 intelligent automatic touch screen controlled oxygen index analyzer

天狮娱乐1. Full color touch screen control, as long as the oxygen concentration value is set on the touch screen, the program will automatically adjust to the oxygen concentration balance and send out a beep sound prompt, avoiding the trouble of manually adjusting the oxygen concentration;

天狮娱乐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 back to the target value during the test, which greatly improves the test accuracy.

天狮娱乐2、 Design criteria:

GB/T 2406.2   GB/T 2406   ASTM D 2863, ISO 4589-2, NES 714   GB/T 5454 GB/T 10707   GB/T 8924   GB/T 16581   NB/SH/T 0815-2010   TB/T 2919

4、 Configuration

Tips: during the test of oxygen index tester, one bottle of industrial grade oxygen / nitrogen of no less than 98% is required as the gas source. As the above gases are high-risk transport products, they can not be provided as accessories of oxygen index analyzer, so they can only be purchased at the user's local gas station. (to ensure the purity of the gas, please purchase it at the local regular gas station)
