ZE-CEM2000(Continuous
Emission Monitoring System) is one of the serial
products made by Shenzhen Environmental Instruments Ltd.The system
takes advantages of the dilution sampling method in large proportion,
the ultraviolet fluorescence spectrometer designed to measure concentrations
of sulfur dioxide(SO2), the gas-phase chemiluminescence¡¯s detection
to perform analysis of total oxides of nitrogen(NOX), the principal
of back laser beam dispersion for monitoring dust emissions, multi-points
pitot tube as a flowmeter, therefore, making use of this system,
the function of continuous monitoring of stack gas, data transmission,
remote failure analysis, large data acquisition, graph analyze can
be realized. The simple constructions, high-precision measure, wide
scope of data trends, low cost of running are the character of this
system. At the same time the whole system use modularized structure,
which will be quite easy to fit together.
