Limited Oxygen Index Tester

Limited & Temperature Oxygen Index Tester, LOI-404, LOI-P04, TOI-504, TOI-P04, ASTM D 2863, ISO 4589-2, ISO 4589-3, NES 714, NES 715 Introduction FESTEC's LOI(Limited Oxygen Index tester) measures minimum oxygen concentration as necessary when specimen combustion. This equipment's the oxygen analyzer is adapted Paramagnetic Type which has a precise, long life, less error rate and high reliability. TOI (Temperature Oxygen Index Tester) measures temperature index of specimen by heated mixing gases on temperature up to 400°C in the atmosphere oxygen concentration. According to ISO 4589-3, high temperature is best factor to assess combustibility of materials better than Oxygen Index.FESTEC's Limited Oxygen Index tester lowers the height of glass chimney, gives data result from DAQ System interfaced with PC. And this has simple design and convenience such as foot switch. This meets the contents of standards like ASTM, ISO, NES, KS and so on. Standard Limited Oxygen Index : ASTM D 2863, ISO 4589-2, NES 714 Temperature Oxygen Index : ASTM D 2863, ISO 4589-3, NES 715 Features Limited Oxygen Index Paramagnetic Cell to measure exact oxygen concentration Automatic Mass Flow Controller to control mixed gas Precision display window on the software to facilitate easy reading of oxygen concentrations Specimen Holder facilitating separation and attachment of test sample Sample support suitable to hard or soft samples Shortest gas route to indicate test results fast DAQ System designed to display all test results to exactly match with each standard Foot switch controller to easily control the DAQ System DAQ System for reproducibility and reliability of test result Simple and compact design Both manual and automatic test Easy maintenance applying to PCB Temperature Oxygen Index Tests under the mixed gases temperature condition to increase up to 400°C High-efficiency band heater enabling pre-heating of mixed gases Temperature Column designed to observe specimen and at the same time emit high temperature radiation Temperature controller enabling temperature adjustment for the pre-heater and temperature column Air Pump designed to prevent safety accident before supplying mixed gases of oxygen and nitrogen and enable flammability test Portable and user-friendly igniter Both manual and automatic test Easy maintenance applying to PCB Specification Model FT-LOI-404, FT-TOI-504 Size 435(W) x 550(D) x 670(H)mm Size(Control) 1,500(W) x 600(D) x 800(H)mm Power AC 220V, 50/60Hz, 5A Weight 50kg Manual Supply Exhaust 50L/s Utilities Oxygen, Nitrogen, Personal Computer(acceptable PCI-Card), Dust Collector Test Result The test specimen form (I to IV) and dimensions Ignition procedure: A, B Oxygen Index value: OI = Cf + kd Estimation of Standard deviation s Step Size, d Special material history/characteristics Variations from standard procedure Description of observed burning behavior Results measured/reported by whom
