NDIR gas analyzer <ZKJK> (substitute for ZRG)

NDIR gas analyzer (substitute for ZRG) <ZKJK>

ZKJK is the substitute for the obsoleted model ZRG.
Size and terminal allocation are designed
same with ZRG for ease of replacement.

  • Simultaneously and continuously measures up to 3 components among NO, SO2, CO, CO2, CH4, and O2

  • Hardly affected by interference from other gases

  • Optional functions include: automatic
    calibration, O2 correction, averaging,
    concentration alarm, remote range-switching,
    and more.

  • Easy-to-see backlit LCD
