Evikon PluraSens E2618-CO-DM Manual

Carbon monoxide
Colourless, odourless, and tasteless gas. Highly toxic.
Synonyms: Carbonous oxide, Carbon(II) oxide, Flue gas, Monoxide
Chemical formula CO
Molar weight 28
Relative gas density (to air) 0.97
Conversion 1 ppm = 1.15 mg/m
Boiling point −191.5 °C
Low explosive limit (LEL), % vol in air 12.5
Upper explosive limit (UEL), % vol in air 74
Odour Odourless
Hazards Highly toxic. Mild poisoning causes
lightheadedness, confusion, headache,
dizziness, and flu-like effects. Larger
exposures can lead to toxicity of the
CNS and heart, and death. After acute
poisoning, long-term problems may
occur. CO also have negative effects
on a baby if exposed during
pregnancy. Chronic exposure to low
levels can lead to depression,
confusion, and memory loss.
Exposure limits TWA 40 mg/m
(NIOSH)
IDLH 1380 mg/m
3
Conversion of ppm to mg/m is calculated for 25°C and 1 atm.
Installation guidelines
(See Installation and connections section for general information.)
Carbon monoxide has practically the same density as air and spreads evenly in the
room. Install the sensor in a proximity to possible leakage or generation source, taking
into consideration the temperature of the gas, the air currents in the room etc.
Calibration
E2618-CO transmitters 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 6 months. 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.
