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)
