Description
Product details
Mainly used to assess the combustion performance of non-metallic materials under the specified test conditions, that is, determine the volume fraction of non-metallic materials just to maintain the minimum oxygen concentration of combustion. Suitable for testing the oxygen index of textiles, plastics, rubber, fiber, wood, insulation materials and their products. Features: 1.The main chassis with PC / ABS synthetic flame retardant materials as a whole abrasive molding. The overall performance is better than pure PC, ABS and metal box. Streamlined design, elegant appearance, free from electromagnetic interference, test more accurate. 2.The first about the push and pull combustion stage and glass tube, can choose to switch the use of the left or right. Not only to meet the different test personnel to use, and rapid response to the standard requirements of the "multiple tests, should be used two combustion tube, such a cooling, two outside a test" Otherwise, the combustion tube cooled to 23⁰C ± 2⁰C, waste test Time, low test efficiency. 3. To improve the old equipment, glass bead diffusion filling method, using a new gas diffusion system, easy installation, while ensuring a more uniform diffusion of gas mixture. 4, the sensor uses the world's leading British CITY imported special sensors to ensure the accuracy of the test. 4. Using PLC & 7-inch high-definition LCD touch screen, related operations completed by the touch screen, real-time display of experimental data. 5. Built-in microcomputer and control program, real-time acquisition, linear analysis of experimental data, and automatic data storage. 6. Built-in time control module, automatic timing of combustion time, overcoming the drawbacks of using separate stopwatch timing and cumbersome. 7. Built-in gas temperature sensor, real-time monitoring and display of gas temperature. 8. Built-in count module, automatically record the number of tests. 9. Configure the mini thermal printer, you can print the test results and other relevant data. 10. The use of constant oxygen concentration in the air one-touch calibration, convenient and accurate test. 11. Solenoid valve control system, you can switch around the combustion stage, easy to operate. Technical Parameter: Combustion tube and the base Quartz glass, diameter 95mm, the total height of 450mm (two sets) The oxygen concentration adjustment range 0 ~ 100%, Resolution: 0.1% Response time <3s Burning time 0-999.9S, accuracy 0.1S Working pressure 0.1MPa ~ 0.3MPa Gas Industrial oxygen and nitrogen (customer to arrange locally) Working power: AC220V, 50Hz, 50W Standards • ASTM D 2863, • ISO 4589-2 Power: AC220V, 50Hz, 50W Dimensions: 830mmX600mmX900mm (W x L x H)
