Because it is a device used in quality control in the production process, there must not be other Butadiene O2 in the manufacturing process, so it is important for the quality system and manufacturing process, if there is O2 within the production process may affect quality and damage to opkon in the production process immediately. The device service must be a person who has expertise and understanding in the operation of the equipment, because the นอุปกรณ์ backpack to measure very low or 0 PPM levels (20% O2 in the air, O2 mol in the process must be 0 ppm, 1 mol% = 10000 PPM)
