PluraSens® Hydrogen Sulfide Detector-Transmitter E2638-H2S 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/m3 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 NO2 which has a pungent odour Hazards Irritates respiratory tract and eyes, at high concentrations may cause lung edema and death. Exposure limits (Directive 91/322/EEC) TWA 30 mg/m3 /25 ppm IDLH (NIOSH) 123 mg/m3 /100 ppm Conversion of ppm to mg/m3 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.
