Oxygen Indexer Testing Machine：
The Oxygen Indexer Testing Machine is designed and de-veloped according to ISO4589-3 (Elevated-temperature test) and British Naval Engi-neering Standard NES 715. Based on the general intelligent oxygen index instrument,the high temperature oxygen index tester adds a electric-heating device at the position of the combustion cylinder to preheat the mixed gas and test the ignition temperature of the different materials at a certain oxygen concentration.

oxygen index tester manufacturers Features:
Imported oxygen concentration sensor (paramagnetic oxygen concentration sensor for model F248A, electrochemical oxygen concentration sensor for model F248D ) showing the oxygen concentration accuracy of ± 0.1%.
High temperature resistant quartz glass tube, outlet diameter 40mm.
Supportive and non-supportive sample holder.
Portable ignition, easy to operate.
Patented gas flow control unit which equipped with mass flow controller mixing nitrogen and oxygen can precisely control the gas flow.
After setting the oxygen concentration on screen, PLC control system can automatically adjusts the oxygen concentration according to the set value , precise and easy control.
The gas mixing chamber with patented design can ensure that the oxygen concentration measurement more accurate and the mixture of oxygen and nitrogen more better.
