High Reliability
z
The OMA-2000 optical fiber spectrometer uses xenon light which lifetime is more than
10 years;
z
The OMA-2000 optical fiber spectrometer uses holographic grating light division and
array sensor which is much more high reliable than mechanical movement parts;
z
The dust detector is adopted with integrated designing which is compact in structure and
high reliable.
Easy and Low Cost Maintenance
z
The probe is designed with special holes layered filter for high performance filtering and
efficient purging. The probe maintenance cycle can be extended;
z
The sampling signal is gathered and connected to PC via OMA-2000 optical fiber
spectrometer which the system cabling is simple and the installation and maintenance
are easy to be carried out;
z
The light source, gas room and spectrometer are connected via optical fiber which
makes the maintenance and replacement of each component easier and at low cost.
High Accurate Measurement
z
The integrated high temperature sampling unit is adopted to ensure that the gas
composition is not changed during the measurement process;
z
The hot wet method (temperature can be set within 120
℃
~200
℃
) is adopted to measure
SO
2
and NO
X
to avoid the incorrect SO

measurement due to the absorption of
condensing water and the corrosion of condensing unit, sampling pump and the meter
by the formed H

SO

;
z
SO
2
and NO
X
are analyzed by ultraviolet differencing technology to eliminate the
influence to the measurement caused by the water, dust or other factors;
z
The dust meter is adopted with laser transmission principle which has high sensitivity
and fast responsibility. It is embedded with auto calibration function with high accuracy
of measurement and high reliability.
