Oxygen Index Tester
According to
ISO 4589-2, ASTM D 2863, NES 714.
Oxygen Index Tester can measure the minimum concentration of oxygen required for combustion of a sample. Oxygen index is an important reference value to measure the flame retardant properties of materials. Oxygen index refers to a certain size of the material (test piece) into the test device, under specified conditions, through the mixed gas of oxygen and nitrogen, the test piece is ignited with an igniter, determine the minimum oxygen concentration necessary to maintain continuous combustion (expressed in percentage). The instrument is imported paramagnetic oxygen concentration sensor, accurate measurement, long life, low error rate, high reliability.
Oxygen Index consists of
·Integrated structure, industrial design appearance, beautiful and generous, easy to operate
·Equipped with two mass flow controllers (MFC), control nitrogen, oxygen mixture ratio, accurate and c.onvenient control.
·Automatic control of closed epoxy concentration, accurate control of oxygen concentration in the combustion tank.
·Patented gas mixing chamber can ensure that the gas is fully mixed in a short time and the data is more accurate.
·Equipped with paramagnetic oxygen concentration sensor, the accuracy of oxygen concentration is ±0.1%, compared with traditional electrochemical oxygen sensor, no service life limit (electrochemical oxygen sensor requires frequent replacement of oxygen cells), higher accuracy, faster response time.
·Equipped with stainless steel supporting and unsupported sample fixture, easy to switch.
·Portable igniter, precision needle valve to adjust flame size.
·Equipped with gas diffusion ring, mixing glass beads, so that the outlet gas more uniform .
·Equipped with high temperature resistant quartz glass barrel, independent design of the end cover for glass barrel cleaning.
·Programmable controller (PLC)+ touch screen control, digital setting of nitrogen and oxygen concentration, without repeated manual adjustment.
·Desktop computer + professional control software to realize the guidance of the whole test process, and store and output test results (optional).
