Limited & temperature oxygen index, ASTM D 2863, ISO 4589-2, ISO 4589-3, NES 714, NES 715
FESTEC’s LOI(Limited Oxygen Index tester) measures minimum oxygen concentration as necessary when specimen combustion. This equipment’s the oxygen analyser is adapted Paramagnetic Type which has a precise, long life, less error rate and high reliability.
TI (Temperature Index Tester) measures temperature index of specimen by heated mixing gases on temperature up to 400℃ 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.

Limited Oxygen Index
① Paramagnetic Cell to measure exact oxygen concentration
② Auto & Manual mode (Select control and analysis by personal computer or user)
③ Automatic Mass Flow Controller
④ Precision display window on the software to facilitate easy reading of oxygen concentrations
⑤ Specimen Holder facilitating separation and attachment of test sample
⑥ Sample support suitted to hard or smooth samples
⑦ Shortest gas route to fast indicate test results
⑧ DAQ System designed to display all test results to exactly match with each standard (It can be make stronger measuring and more correct & fine test result and also more powerful repeatable performance)
⑨ Foot switch controller to easily control the DAQ System
⑩ Simple and compact design
⑪ Oxygen Transducer from HUMMING BIRD SENSING TECHNOLOGY
Temperature Oxygen Index
① Tests under the mixed gases temperature condition to increase up to 400℃
② High-efficiency band heater enabling pre-heating of mixed gases
③ Temperature Column designed to observe sample and at the same time emit high-temperature radiation
④ Temperature controller enabling temperature adjustment for the pre-heater and temperature column
⑤ Air Pump designed to prevent safety accident before supplying mixed gases of oxygen and nitrogen and enable flammability test
⑥ Portable igniter
Oxygen concentration, standby temperature, ignition time, and combustion time for the Limited Oxygen Index Tester are measured with DAQ Board and Foot Switch, and deviation of measured values and oxygen index values are automatically calculated to print out result sheet.
Also, the Temperature Oxygen Index Tester adopts the Sample Temperature Thermocouple to measure temperature of mixed gases and automatically perform Elavated Temperature Oxygen Index and Flammability Temperature test on the Software.
