TM-801 CO meter is used for measuring the CO levels to 1000ppm.
Carbon monoxide (CO) is a poisonous gas that has no smell, color or taste. But it is very dangerous and reduces the oxygen-carrying capacity of blood that causes you unwell, illness and death.
CO LEVELS AND STANDARD:
| Carbon monoxide content in the air | Inspiration time | Symptoms and applicable standard |
| 0-1 ppm | Normal background levels. | |
| 9 ppm | Maximum indoor air quality level. | |
| 35 ppm | 8 hours | The average exposure level per U.S. OSHA workplace standards. |
| 50 ppm | 8 hours | The maximum average exposure of the U.S. OSHA workplace standards. |
| 0.01%(100 ppm) | 2~3 hours | evacuate people from enclosed space if the CO concentration exceeds 100 ppm per OSHA exposure limit.Mild headache. |
| 0.04%(400 ppm) | 1~2 hours | Headache occur in 2.5 hours to 3.5 hours. |
| 0.08%(800 ppm) | 45-min | Dizziness, nausea, cramps(convulsions). |
| 0.16%(1600 ppm) | 20-min | Headache, dizziness and will be dead within 2 hours. |
| 0.32%(3200 ppm) | 5~10 min | Headache, dizziness, vomiting and will be dead in 30 minutes. |
| 0.64%(6400 ppm) | 1~2 min | Headache, dizziness and will be dead within10 to 15 minutes. |
| 1.28%(12800 ppm) | 1~3 min | Cause death. |
