Notes on carbon monoxide
Carbon monoxide is a highly toxic gas for humans even in very
low concentrations.
It is invisible, tasteless and odourless.
The following table gives you a summary of the effects which
specific CO concentrations in the air have on humans.
Concentration in the air Inhalation time and effects*
30ppm 0.003Vol.% Max. workplace concentration during an 8 hour working day
(limit value for Germany)
200ppm 0.02Vol.% Light headache within 2-3h
400ppm 0.04Vol.% Ache in forehead area within 1-2h, spreading to whole head
area
800ppm 0.08Vol.% Dizziness, nausea and limb twitching within 45min,
unconscious withing 2h
1600ppm 0.16Vol.% Headache, dizziness, nausea within 45min,
dead within 2h
3200ppm 0.32Vol.% Headache, dizziness, nausea within 5-10min,
dead within 30min
6400ppm 0.64Vol.% Headache, dizziness, nausea within 1-2min,
dead within 10-15min
12800ppm 1.28Vol.% Dead within 1-3min
* The above concentrations are approximate values. Humans react differently to CO concentrations depending on
height, age, sex and state of physical health.
testo AG does not accept any responsibility for the accuracy of the above data.
Instruction manual
Intended use
The testo 317-3 CO monitor determines the existence of carbon
monoxide (CO) in the environment and warns the user visibly and
audibly about dangerous gas concentrations,
e.g. during installation and maintenance work on gas heaters.
Do not use testo 317-3 as a monitoring instrument for personal
safety.
