NDIR Type Infrared Gas Analyzer _ ZKJ-6
ZKJ-6 measures the concentration of NO, SO2, CO2, CO, CH4, N2O and O2 in sample gas.
NDIR(Non-dispersive InfraRed) spectroscopy is used for NO, SO2, CO2, CO, and CH, and O2 is measured with a built-in paramagnetic sensor or external zirconia analyzer. The instrument can measure a maximum of 5 components including O2 (4 without O2) simultaneously.
The double-beam NDIR detector with a mass flow sensor has high sensitivity and reliability and is hardly affected by interference from other gases.
The instrument is also abundant with various features including 02 conversion calculation, auto-calibration of mean value calculation, and one-touch calibration. Thanks to its large display, it is easy to read all the measurements and calculation results.
