Limiting Oxygen Index Tester, Oxygen Index Testing Equipment
Introduction:
The critical oxygen index tester is suitable for determining the minimum oxygen concentration required to maintain the combustion test under the specified test conditions in the mixture of oxygen and nitrogen. The analyzer is equipped with an imported mass flow controller, which provides accurate measurement and durability. Used to evaluate the combustion performance of homogeneous solid materials, laminates, foams, films, and films under specified conditions.
Features:
- Adopts England 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 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, a fine filter, so, it is stable and safe;
- Patented design gas mixing chamber, which ensures the gases can mix the gases in a short time, data is more accurate;
