Simultaneous, continuous measurement of 5 gases
Fields of application
ZKJ is particularly suitable for industrial furnaces, boilers and all types of combustion installations.
Benefits
The ZKJ gasanalyser can simultaneously and continuously measure up to 5 of the following gases: NO, SO2 , CO2, CO, CH4, N2O by the non-dispersive infrared method, while O2 is measured by the paramagnetic or zirconium
by the paramagnetic or zirconia method. It provides extremely reliable measurement thanks to two mass flowmeters that are unaffected by interfering gases. It offers high accuracy, numerous features and ease of use. The ZKJ is particularly well suited to industrial furnaces, boilers and all types of combustion installations.
