Description
Multi-component infrared analyzers and cross-stack laser analyzers meet EPA requirements for stack emission monitoring. The ZSU and ZSJ continuously measure NOx, SO2, CO, CO2 and O2. The ZSU has a double-beam non-dispersive infrared (NDIR) sensor with long-term stability and auto-calibration, the ZSJ a single-beam sensor with sample switching and a stable zero without drift, and both systems have Japanese type approval. The ZSU-7 adds HCl and dust. The separate NDIR analyzers are the double-beam ZKJ (NO, SO2, CO, CO2, N2O, CH4, O2, ranges from 0–20 ppm, auto-calibration, range ratio 1:25) and the compact single-beam ZPA. For oxygen there are zirconia in-situ ZKM and ZFK8 with the HART protocol, explosion-proof ZKME and ZFKE for hazardous areas, and the paramagnetic ZAJ. The range is completed by thermal conductivity ZAF and explosion-proof ZAFE, the ZPAF biogas analyzer, an aerosol analyzer and sampling devices.
How to choose
First determine the task, environmental emission monitoring or combustion control. For CEMS the ZSU or ZSJ is chosen, and for seven parameters with HCl and dust the ZSU-7. The ZSU is chosen when long-term stability and auto-calibration are needed, the ZSJ when a stable zero matters. Separate measuring points are covered by the ZKJ or ZPA, for boiler combustion the ZKM or ZFK8 is installed, and in hazardous areas the ZKME or ZFKE work.

FAQ
Which gases do the ZSU and ZSJ systems measure?
NOx, SO2, CO, CO2 and O2, up to five components. The ZSU-7 adds HCl and dust, up to seven parameters in total.
How does the ZSU differ from the ZSJ?
The ZSU has a double-beam NDIR sensor with auto-calibration, the ZSJ a single-beam one with sample switching and a stable zero without drift.
What is the measuring range of the ZKJ?
The double-beam NDIR works from 0–20 ppm with auto-calibration, range ratio 1:25. It measures NO, SO2, CO, CO2, N2O, CH4 and O2.
Which oxygen analyzer should be used for boiler combustion control?
Zirconia in-situ ZKM or ZFK8 with HART. For hazardous areas there are explosion-proof ZKME and ZFKE.
Do these analyzers meet EPA requirements?
Yes, multi-component infrared and laser analyzers meet EPA requirements for emission monitoring. The ZSU and ZSJ also have Japanese type approval.
