Evikon PluraSens E2608-NO User Manual

Nitric oxide
Colourless toxic gas, relatively insoluble in water. When exposed to oxygen
(including air), nitric oxide is converted into nitrogen dioxide.
Chemical formula NO
Molar weight 30
Relative gas density (to air) 1.03
Conversion 1 ppm = 1.23 mg/m
Boiling point -152 °C
Flammability Nonflammable, but accelerates the
burning of combustible materials.
Odour Pure NO is odourless, but in the air it
oxidizes to NO
odour
Hazards Irritates respiratory tract and eyes, at
high concentrations may cause lung
edema and death.
Exposure limits TWA 30 mg/m
(Directive 91/322/EEC)
IDLH (NIOSH) 123 mg/m
Conversion of ppm to mg/m 3 is calculated for 25°C and 1 atm.
Installation guidelines
(See Installation and connections section for general information.)
Nitric oxide has practically the same density as air. As it is easily oxidized to form
nitrogen dioxide, the sensor should be placed as close as possible to the gas source.
Calibration
E2608-NO detectors have been calibrated by Manufacturer with standard gas
mixtures before delivery. Provided that the sensor is used under moderate
conditions,the recommended interval for field recalibration is 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.
