cross stacK laser Gas analYZer
DATA SHEET
Cross stack laser gas analyzer (ZSS) provides continuous
measurement of density of HCl contained in flue gas in an
incineration system, NH3 in denitration equipment, com-
bustion gas, CO, CO2 and O2 with quick response speed.
Due to in-situ method, Measured gas does not require the
preparation by sampling system. This analyzer can be
used under high dust conditions, so it is possible to install
upstream of the bagfilter where gas sampling is normally
difficult.

Features
1. Maintenance is minimized thanks to no need of gas sam-
pling devices.
2. Running cost is negligible due to having few expendable
parts.
3. Zero drift is within ±2.0%FS, and an excellent stability is
ensured for a long period of time.
4. Almost no interference by other gas component be-
cause an infrared semiconductor laser, which has exact
absorption wavelength as the measured component, is
used.
5. High speed response is available since the gas sampling
device is unnecessary.
6. High vibration resistance because the optical adjust-
ment mechanism is separated from the airtight compart-
ment, and it is easy to make a fine adjustment and large
adjustment angle.
