CONTINUOUS
EMISSIONS MONITORING
SYSTEM (CEMS) II
The Gasmet CEMS II FTIR measuring system is designed for
continuous emissions monitoring measurements (CEM).
Typical application is H2O, CO2, CO, N2O, NO, NO2, SO2, HCl,
HF, NH3, CH4, C2H6, C3H8, and C2H4 monitoring from waste
incinerator or large combustion plants. Measured components
and calibration ranges can be changed according to
application.
The Gasmet CEMS II is an ideal tool to use for measuring
trace concentrations of pollutants in wet, corrosive gas
streams. All parts of the Gasmet CEMS II are be heated up to
180 ºC. It can be used for undiluted gases and the sample
gases do not need drying beforehand.
The Gasmet CEMS II consists of Gasmet FTIR gas analyzer,
Gasmet industrial computer, and Gasmet sampling system. As
an option the system can be equipped with ZrO2 oxygen
analyzer and/or with total hydrocarbon analyzer (FID). All parts
of the system are 19” rack mounted and are installed on the
pull-out shelves. The Gasmet CEMS II includes all power
connections and temperature controllers for heated lines and
heated sample probe. The operation of the system is fully
automatic and controlled by the Calcmet software. Additionally
all functions of CEMS II can be controlled manually.
Comprehensive I/O functions make possible to connect CEMS
II into all kind of automation or reporting systems. Measuring
data and alarms can be transferred from Gasmet CEMS II to
other systems with analog or digital format. Gasmet CEMS II is
also equipped with analog / digital inputs for external data
(other analyzers or process).
Gasmet CEMS II provides different alarm functions such as
System alarm, Service request, Maintenance on progress (can
be set also manually), Concentration alarm, and Result valid.
Combination for each alarm can be set on Calcmet. If any of
the critical alarm is activated, instrument air starts to flow
automatically into the system to prevent condensation.
Standard CEMS II is equipped with a two solenoid valve to
allow automated span/zero checks as required by the new
legislation.

General parameters

Gasmet CEMS II is air conditioned with a compressor-cooling
unit on top of the cabinet. Cabinet includes ready made
through-leading rubbers on each side and top of the cabinet
for all cables and lines. Gasmet CEMS II is also supported by
full remote control.
The Gasmet CEMS II FTIR has a very low cost of ownership;
the equipment is extremely well designed, and requires very
little maintenance. The system also has a number of in-built
failsafe devices to protect the instrument from potential
damage.
