Automatic Limited Oxygen Index Loi Analyzer ASTM D 2863

GD-01005 Automatic ASTM D 2863, ISO 4589-2 Limited Oxygen Index LOI Analyzer

Introduction:

• The oxygen index tester is designed to test combustibility by oxygen concentration, letting the user know the minimum oxygen concentration 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.

Reference Standards:

ASTM D 2863

Specifications:

Features:

• Adopts England's original Servomex Paramagnetic type oxygen sensor, which accuracy can be up to +/-0.1%;

• The sensor is better than the traditional electrochemical sensor because it doesn't need to change the oxygen battery, so, it has long lift time more accuracy, 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, and 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, a fine filter, so, it is stable and safe;

• Patented design gas mixing chamber, which ensures the gases can mix the gases in short time, data is more accurate;
