Automatic Computer Control Oxygen Index Testing Machine

Introduction:

• LOI-A Automatic Computer Control Oxygen Index Testing Machine 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:

• 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.

• Equipped with 2pcs Mass Flow Controller(MFC) to control N2 and O2 mixing ratio;

• Equipped with high temperature quartz glass tank;

• Equipped with supported and unsupported sample clamps;

• Equipped with 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;
