Introduction
FESTEC’s LOI (Limited Oxygen Index tester) measures minimum oxygen concentration as necessary during specimen combustion. This equipment’s oxygen analyzer adapts the Paramagnetic Type which is precise, has a long life, a minimized error rate and high reliability. TOI (Temperature Oxygen Index Tester) measures the temperature index of the specimen by heated mixing gases at a temperature of up to 400℃ in an atmosphere oxygen concentration. According to ISO 4589-3, high temperature is the best factor to assess combustibility of materials better than the Oxygen Index. FESTEC's Limited Oxygen Index tester lowers the height of glass chimneys, gives data result from DAQ System interfaced with PC. This has a simple design and provides convenience such as the foot switch. This meets various standards such as ASTM, ISO, NES, KS and so on.


Features
*Limited Oxygen Index
①Paramagnetic Cell to measure exact oxygen concentration
②Auto & Manual mode (Select control and analysis by personal computer or user)
③Automatic Mass Flow Controller
④Precision display window on the software to facilitate easy reading of oxygen concentrations
⑤Specimen Holder facilitating separation and attachment of test sample
⑥Shortest gas route to fast indicate test results
⑦DAQ System designed to display all test results to exactly match with each standard (It can allow for stronger measuring and output a more precise test result with more powerful repeatable performance)

*Temperature Oxygen Index
①Tests under the mixed gases temperature condition to increase up to 400℃
②Temperature Column designed to observe sample and at the same time emit high-temperature radiation
③Temperature controller enabling temperature adjustment for the pre-heater and temperature column
