Apparatus to determine the minimum concentration of oxygen that will just support flaming combustion of plastic materials such as polymers, cables, rubber, nylon, laminates, paints, surface coating etc. in a flowing mixture of oxygen and nitrogen, in conformity with ASTM D-2863, BS 2782 PT-141, and ISO-4589.

Oxygen Oxygen percentage :     0~100%
Resolution :                                  0.01
Accuracy :                                     0.5%

All Stainless Steel construction including Control Box Controls : Solid State Gas Distribution & Control : SMPS based Power Supply to enable operation over a large Supply range 200-250V/ 90~125 Volts Ac, , single phase

Oxygen Sensors : Imported O2 Sensor with special filter (4 micron) and precision gas regulator with locking facility for long life of sensor and reliable measurements.

Applications:
The test method of the critical oxygen index test apparatus covers a fire test response procedure which is for measuring minimum concentration of oxygen in a flowing mixture of oxygen & nitrogen that will just support the flaming combustion.
