Brief introduction: Critical oxygen index apparatus, is suitable for the determination of the experimental conditions, the oxygen and nitrogen in the mixed gas just keep sample minimum oxygen concentration needed for combustion. This tester for import oxygen concentration sensor, measurement accuracy, durability, precision. Used for evaluation of homogeneous solid materials, laminated materials, foam materials, film and film combustion performance under specified conditions. Features: 1. Import the oxygen concentration of paramagnetic oxygen sensors, display precision of oxygen concentration of plus or minus 0.1% 2. Equipped with high temperature resistant quartz glass tube, exit diameter of 40 mm; 3. Equipped with can support and without support the sample holder 4. The mass flow controller, according to the set concentration automatic regulating oxygen and nitrogen gas flow; 5. Set the screen after oxygen concentration, PLC control system according to the set value automatically adjust oxygen concentration. Control precision, convenient. 6. LCD real-time display parameters such as flow rate, time, and the experimental results. 7. Double flow meter and pressure gauge device: accuracy + / - 1% 8.
