Precautions to be taken before testing the fully automatic oxygen index analyzer

Matters required before testing the YZS-10A fully automatic oxygen index tester——Xinsheng Zhuorui YZS-10A Oxygen Index Tester has a high degree of automation,The automatic oxygen index tester of Beijing Xinsheng Zhuorui Technology Co., Ltd. is applicable to the combustion performance measurement of wire and cable, plastic, rubber, fiber, foam plastic, film and film, textile and other materials. It is a new type of product developed according to the technical requirements specified in GB/T2406. The fully automatic oxygen index analyzer is used to measure the volume percentage of oxygen required during the combustion process of polymers. The polymer oxygen index value is the low oxygen concentration (also known as oxygen index) required to maintain combustion for 50mm or 180s in the oxygen and nitrogen mixture airflow after the substance is ignited. The fully automatic oxygen index analyzer can not only be used as a means of identifying the flame retardancy of polymers, but also as a research tool, providing powerful testing methods for laboratory research on flame retardant formulas and the development of new flame retardant materials.
Precautions to be taken before testing the fully automatic oxygen index analyzerDesign standard for fully automatic oxygen index analyzer: GB/T 2406.2-2009 GB/T 2406.1-2008
The fully automatic oxygen index tester meets the standards of ASTM D 2863, ISO 4589-2, NES 714 GB/T 5454 GB/T 10707 GB/T 8924-2005 GB/T 16581-1996 NB/SH/T 0815-2010 TB/T 2919-1998 IEC 61144-1992 ISO 15705-2002 ISO 4589-2-1996

YZS-10A fully automatic oxygen index tester with touch screen control (with smoke exhaust hood) Product advantages:
1. Full color touch screen control, simply set the oxygen concentration value on the touch screen, and the program will automatically adjust to the oxygen concentration balance and emit a beep sound prompt, eliminating the trouble of manually adjusting the oxygen concentration; One click calibration of oxygen concentration and data storage;
2. The step proportional valve is used to greatly improve the flow control accuracy. The closed-loop control is used to automatically adjust the oxygen concentration drift program to the target value during the test, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test, and greatly improves the test accuracy;
3. The equipment comes with a fume hood that can automatically exhaust smoke;
