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
