Flue Gas Analyzer System ZSU

Continuous monitoring of up to 5 components:
NOx, SO2, CO, CO2, and O2

Ideal for flue gas monitoring in waste incinerators, boilers, and furnaces

  • Space-saving design
  • A variety of functions: auto calibration, O2-corrected output, averaging, alarm, etc.
  • Japanese type approval
