Product Description
ISO 15705 Intelligent Automatic Touch Screen Control Oxygen Index Tester LOI Test Apparatus
I. Advantages of LR-5 intelligent automatic touch screen control oxygen index tester
1. Full-color touch screen control, just set the oxygen concentration value on the touch screen, the program will automatically adjust to the oxygen concentration balance and issue the sound of beep, eliminating the trouble of manually adjusting the oxygen concentration;
2. The stepping proportional valve greatly improves the control accuracy of the flow, and the closed-loop control is adopted. During the test, the oxygen concentration drift program automatically adjusts back to the target value, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test and greatly improves the test accuracy.

Ii. Main technical parameters of LR-5 intelligent automatic touch screen controlled oxygen index tester
Iii. Design standard
GB/T 2406.2-2009
Tips: when testing oxygen index tester, one bottle of industrial-grade oxygen/nitrogen of no less than 98% should be used as gas source. As the above gas is high-risk transport, it cannot be used as accessories of oxygen index tester, so it can only be purchased from local gas stations of users.(in order to ensure the purity of the gas, please purchase it at a local regular gas station)
