NDIR gas analyzer (ZKJK) (substitute for ZRG)
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
