OI economic oxygen index tester Introduction: Under the specified test conditions, such as indoor temperature, in the oxygen-nitrogen mixed gas stream, the method of measuring the minimum oxygen concentration required to maintain the sample combustion is defined as the oxygen index. According to the different ambient temperature during combustion, it can be divided into room temperature oxygen index method and high temperature oxygen index method. It is generally believed that the higher the oxygen index, the better the flame retardant performance of the material, and the lower the oxygen index, the easier the material is. ignite. Features: 1. Using modern oxygen sensor technology, the percentage of oxygen can be automatically obtained; 2, digital display of oxygen percentage concentration, reading accuracy of 0.1%; 3, using a precision metering gas flow valve to adjust the gas flow, can accurately adjust the flow of oxygen and nitrogen; 4, oxygen percentage step adjustment, adjustment accuracy can be 0-0.2L / Min; 5, equipped with nitrogen and air pressure reducing valve, the output pressure can be adjusted to 0.1mpa; 6, external electrochemical sensor, easy for users to replace; 7, high temperature quartz glass cylinder, can withstand higher test temperatures; 8, equipped with a gas igniter device, can easily adjust the length of the flame and has the function of cutting off the combustion gas; 9. Modern design appearance, with a more exquisite design than similar products; 10. Provide relatively simple instrument installation manual files and operation files for users to use. Technical Parameters: Dimensions: 370 mm (W) x 300 mm (D) x 480 mm (H) Weight Weight: 8KG Power requirements: 220V, 10A Ambient temperature: 10 ° C to 35 ° C Installation space: fume hood placement Gas requirements: nitrogen, oxygen
