NDIR Gas Analyzer (ZPAJ) (substitute for ZRJ)

ZPAJ is a substitute for the obsoleted model ZRJ. 

Size and terminal allocation are designed same with ZRJ for ease of replacement.

  • Continuously measures SO2, CO, CO2, CH4, NO, O2
  • Hardly affected by interference from other gases
  • Optional functions include: automatic calibration, remote range-switching, rage identification output, and more.
  • Easy-to-see backlit LCD
