Carbon dioxide
Synonyms: Carbonic acid gas, Carbonic anhydride, Carbon (IV) oxide; Dry ice (in
solid state).
Chemical formula CO
2
Molar weight 44
Relative gas density (to air) 1.52
Conversion 1 ppm = 1.80 mg/m
Boiling point Sublimes
Flammability Nonflammable
Odour Odourless
Hazards Dusts of various metals (Mg, Zr, Ti, Al,
Cr, Mn) are ignitable and explosive when
suspended in carbon dioxide.
In concentrations up to 1% (10 000
ppm), it will make some people feel
drowsy and give the lungs a stuffy
feeling. Concentrations of 7% to 10%
(70 000 to 100 000 ppm) may cause
suffocation, even in the presence of
sufficient oxygen, manifesting as
dizziness, headache, visual and hearing
dysfunction, and unconsciousness within
a few minutes to an hour.
Exposure limits TWA 9000 mg/m
(Directive 2006/15/EC)
STEL Not specified
Conversion of ppm to mg/m 3 is calculated for 25°C and 1 atm.
Indoor air quality in nonresidential buildings
CO2 level Description
< 450 ppm High quality (fresh air)
450-600 ppm Medium quality
600-1000 ppm Moderate quality
> 1000 ppm Low quality
Installation guidelines
(See Installation and connections section for general information.)
Since CO2 is heavier than air, it is recommended to locate the sensor not higher, than
the potential leakage. For air quality control place the sensor in the breathing zone.
Calibration
E2608-CO2 series detector have been calibrated by Manufacturer with standard
gas mixtures before delivery. Provided that the sensor is used under moderate
conditions, field recalibration is recommended every 5 years. Please contact your
dealer for more information.
Maintenance
Do not perform any maintenance operation with the power on.
Clean the device with soft damp cloth. Do not use any abrasive cleaning agents. Do
not immerse the device into water or any cleaning media.
