Limited & Temperature Oxygen Index Meter, ASTM D 2863, ISO 4589-2, ISO 4589-3

Introduction:
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.

TOI (Temperature Oxygen Index Tester) measures temperature index of specimen by heated mixing gases on temperature up to 400ºC in the atmosphere oxygen concentration. According to ISO 4589-3, high temperature is best factor to assess combustibility of materials better than Oxygen Index. 

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 
Auto & Manual mode (Select control and analysis by personal computer or user) 
Automatic Mass Flow Controller 
Precision display window on the software to facilitate easy reading of oxygen concentrations 
Specimen Holder facilitating separation and attachment of test sample 
Sample support suitted to hard or smooth samples 
Shortest gas route to fast indicate test results 
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) 
Foot switch controller to easily control the DAQ System 
Simple and compact design 
Oxygen Transducer from HUMMING BIRD SENSING TECHNOLOGY
 

Temperature Oxygen Index 
Tests under the mixed gases temperature condition to increase up to 400ºC 
High-efficiency band heater enabling pre-heating of mixed gases   
Temperature Column designed to observe sample 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 igniter
 

DAQ System
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.
