Limited Oxygen Index Chamber , Computerized Oxygen Index Apparatus
The limited oxygen tester can test the minimum concentration of
oxygen required for the combustion of the sample. Oxygen index is a
very important reference value to measure the flame retardant
properties of materials. The oxygen index refers to the size of the
material (specimen) loading test device, under specified
conditions, the mixed gas into oxygen and nitrogen, the specimen is
ignited by the igniter, the determination of minimum oxygen
concentration must maintain continuous combustion (expressed as
percentage). The test instrument for the import of paramagnetic
oxygen concentration sensor, accurate measurement, long life, low
error rate, high reliability.
D ASTM 2863, 4589-2 NES, ISO 714
1, oxygen concentration measurement range: 100% - 0
2, resolution: 0.1%
3, accuracy: + 0.2%
4, response time: <300ms
5, oxygen concentration stable time: <6s
1 UK Servomex paramagnetic oxygen sensor, oxygen concentration
display accuracy is + 0.1%, compared with the traditional
electrochemical oxygen sensor, without limitation of service life
(electrochemical oxygen sensor need to replace the battery, oxygen
often) of higher accuracy, faster response time
2 equipped with 2 mass flow controller (MFC), the control of
nitrogen and oxygen mixture ratio, control precision and
3 automatically realize the concentration control of closed epoxy,
precise control of oxygen concentration in the combustion barrel.
4 equipped with high temperature resistant quartz glass tube.
5 equipped with support and no support test specimens
6 portable tank equipped with ignition, quick connector, precise
needle connected to the size of the flame.
7 the number of nitrogen, oxygen concentration, no need to
repeatedly adjust the human.
8 desktop computer + professional control software, to achieve the
entire test process to guide, and store the output test results.
9 the calibration interface is set aside to facilitate the
calibration and measurement of the sensor.
10 stainless steel gas path design, equipped with one-way fire
valve, solenoid valve, precision filter, more safe and reliable.
11 patented design of the gas mixing chamber, can ensure that the
gas in a short time to fully mixed, the data is more accurate.
