| titleOfInvention | High-precision ozone concentration detection system |
| abstract | The utility model discloses a kind of high-precision ozone concentration detection systems, including filter device, detection device, volume control device, vacuum pump；The filter device is connected to the detection device with zero air outlet pipe by sample air outlet pipe；The detection device is connected to the volume control device by pipeline；The detection device is connected to the vacuum pump by pipeline.The utility model is by first removing the air in ozone tunnel using vacuum pump, then carries out zero air detection；It is removed in ozone tunnel using vacuum pump simultaneously and remains zero air, then carry out sample air detection, effectively reduced the influence of other gases in detection process, improve detection accuracy. |
