Gasmet DX4000 is a portable FTIR gas analyzer which is typically used in stack emissions monitoring, comparison measurements, catalytic process control and other applications where multiple gas compounds need to be accurately monitored in hot & humid sample gas. The corrosion resistant sample cell is heated to 180 C, which ensures that the sample stays in gaseous phase even with high concentrations of H2O or corrosive gases.

Gasmet DX4000 is typically set-up to measure H2O, CO2, CO, NO, NO2, N2O, SO2, NH3, CH4, HCl, HF and different VOC´s. Additional gases can be added without any hardware changes. Measurement ranges can be selected from sub-ppm until vol-% level.
Gasmet DX4000 can be supplied with the Gasmet portable sampling system. This system utilizes hot-and-wet measurement principle (no drying or dilution), which ensures that the analysis is done with a representative sample. The portable sampling unit can be optionally equipped with a ZrO2 sensor for accurate oxygen measurement.
Gasmet DX4000 has received the coveted MCERTS certification for stack emissions monitoring.
The Gasmet Portable Sampling Unit is used for on-site measurements. It can be used for measuring trace concentrations of pollutants in wet, corrosive gas streams. The sample gas can be measured undiluted and without drying since the sample pump, heated filter and valve are located in a module that is heated to 180 ºC. From the Sampling Unit the gases can be directed into Gasmet FTIR gas analyzer.
The Gasmet Portable Sampling Unit includes power connections and temperature controllers for heated lines and heated module. The Gasmet Portable Sampling Unit is connected to an external PC through Gasmet FTIR Gas Analyzer and can be controlled by Calcmet software.
The function of the Portable Sampling Unit is automatic, but sample pump and valve can be controlled also manually.
In the case of a power failure or if the temperature (pump, lines, sample cell) is below setting, the automatic 3-way valve switches sample gas to zero gas to prevent condensation. Sample pump can not be switched on before all temperatures have reached the setting. In addition, the zero calibration of the Gasmet FTIR gas analyser can be done automatically with the Portable Sampling System.
As an option, the sampling unit can be equipped with a sample probe and / or heated lines. The maximum length for the heated line is 19m + 1m with 230 VAC and 9m + 1m with 115 VAC power supply. There is also an optional integrated O2 – sensor that supplements the capabilities of the Gasmet FTIR gas analyzers.
Some key benefits of the Gasmet portable measuring system include:
