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 andreduces 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
