TESTech Limit Oxygen Index Tester is designed according to ISO4589.1-2006, it applies to analysis the minimum oxygen concentration needed to maintain combustion of the sample when the sample is under under the test conditions specified in oxygen and nitrogen mixed gas;
This tester is installed with England imported Oxygen sensor, and automatic control the Oxygen and nitrogen flow with mass flow control meter. It is very easily and quickly to operate; Used for evaluating homogeneity of solidmaterials, laminates, foam, film and thin film in the specified conditions of flammability.
1, Oxygen concentration measurement range: 0-100%;Accuracy of ± 2, Oxygen concentration 0.1%
2, Oxygen Mass flow meter range: 0~15.0L/min
3, Nitrogen Mass flow meter range: 0~15.0L/min
4, Response time: <10s
4,Oxygen concentration measurement accuracy: ± 0.4%
5, Combustion tube top airflow 90mm ± 10MM/s
6,Combustion air flow in cylinder 6, 40mm/s ± 2mm/s, concentration control accuracy ± 0.1%
7,Measurement time, accuracy ± 0.5S
8,Portable igniters, Jet flame down 16± 4mm adjustable;
9,Double flow meter and pressure gauge devices: precision: 1%
1,England Imported ParaMagnetic oxygen sensor, accuracy is ± 0.1% ; without working life limit, it is definitely difference with electrochemistry oxygen sensor. (It is difference with electrochemistry sensor, no need to change the sensor every year.)
2,Equipped with heat-resistant quartz glass tube, export ID 40mm;
3,Equipped with supporting and not supporting sample holder
4,Mass flow controllers, automatic regulating oxygen and nitrogen gas flowaccording to the set concentration;
5,Patent design of oxygen and nitrogen mixed unit to make sure the gas is mixed entirely
6,The expected oxygen concentration is set on screen, and PLC control system; No need manually operation;
7, LCD screen show test data such as flow rate, time, results in real time and oxygen concentration etc .
1, PLC with touch screen system to make the test high automation;
2, After setting the oxygen concentrations, the system automatically adjustingthe oxygen concentration;
3, Key electrical components adopt imported brands, accurate, reliable, anddurable;
4, Equipped with a protection circuit;
Smoke Density System(Optional)
1, Optical absorption range: 0-100% can be measured continuously. Smoke density resolution 0.1%
2, Measurement of smoke density is accuracy: ± 3%;
3, Optical glass is easy to be cleaned, avoid to the negative of dust particles;
4, Light resource is 6V instrument special purpose incandescent lamps;
5, System is equipped with calibration system for light transmittance;
