  • Page 2 • Modification of this analyzer is strictly prohibited unless a written approval is obtained from the manufacturer. Fuji Electric will not bear any responsibility for a trouble caused by such a modification. • This instruction manual shall be stored by the person who actually uses the analyzer.

  • Page 3: Caution On Safety

    CAUTION ON SAFETY First of all, read this “Caution on safety” carefully, and then use the analyzer in the correct way. • The cautionary descriptions listed here contain important information about safety, so they should always be observed. Those safety precautions are ranked in 3 levels, “DANGER”, “CAUTION” and “PROHIBITION”.
  • Page 4 Caution on piping In piping, the following precautions should be observed. DANGER Wrong piping may cause gas leakage. If the leaking gas contains a toxic component, there is a risk of serious accident being induced. Also, if combustible gas is contained, there is a danger of explosion, fire or the like occurring.
  • Page 5 Caution on use • Do not allow metal, finger or others to touch the input/output PROHIBITION terminals in the instrument. Otherwise, shock hazard or injury may occur. • Do not smoke nor use a flame near the gas analyzer. Otherwise, a fire may be caused.

  • Page 8: Overview

    1. OVERVIEW This infrared gas analyzer (type: ZKJ) measures the concentration of NO, SO , CO , CO and CH con- tained in sampling gas on the principle that different atomic molecules have an absorption spectrum in the wave band of infrared rays, and the intensity of absorption is determined by the Lambert-Beer law. Since this instrument incorporates a compact paramagnetic O sensor, it allows measuring up to 5 compo- nents simultaneously by using the built-in O...
