Computer Control Automatic LOI Tester for Limited Oxygen Index Testing
Introduction:
-
LOI-A Automatic LOI Tester is designed to test combustibility by oxygen concentration, letting user know minimum oxygen concentration as necessary for combustion.
-
The working principle is: Place the specimen into the testing chimney, filling with oxygen and nitrogen into the chimney, ignite the specimen, then measure the min concentration of oxygen to support continuous combustion.
Features:
- LOI-A Automatic LOI Tester adopts England original Servomex Paramagnetic type oxygen sensor, which accuracy can be up to +/-0.1%;
- The sensor is better than traditional electrochemical sensor, because it don’t need to change oxygen battery, so, it has long lift time more accurate and faster response time.
- LOI-A Automatic LOI Tester is equipped with 2pcs Mass Flow Controller(MFC) to control N2 and O2 mixing ratio;
- Limited Oxygen Index Tester is provided with high temperature quartz glass tank;
- The LOI tester adopts supported and unsupported sample clamps;
- Limited Oxygen Index Testing equipment has portable ignition device, gas tank connector, accurate pin valve to adjust the flame;
- Digital setting N2 and O2 concentration;
- Computer+LABVIEW software to control N2 and O2 mixing ratio, read O2 concentration in mixing chamber, and store&print out test results;
- Reserve a calibration port to calibrate the sensor;
- Stainless steel air channel design, equipped with one way fire-resistance valve, magnetic valve, fine filter, so, it is stable and safe;
- Patented design gas mixing chamber, which ensure the gases can mix the gases in short time, data is more accurate;
