| titleOfInvention | Sulfur dioxide filter device for sampling indoor air formaldehyde |
| abstract | The utility model discloses a sulfur dioxide filter equipment is used in sampling of indoor air formaldehyde mainly relates to sulfur dioxide filtration technical field in the formaldehyde gas sample that awaits measuring. The filter tube comprises a spiral filter tube, wherein manganese sulfate filter paper for filtering sulfur dioxide is attached to the inner surface of the spiral filter tube; the bottom of the sampling air supply channel with the opening at the bottom of the spiral filtering pipe is communicated. The beneficial effects of the utility model reside in that: the device can filter sulfur dioxide gas in the air to avoid sampling interference, so that the accuracy of a detection result after sampling is ensured. |
