Gasmet portable sampling unit

The Gasmet portable sampling unit has been designed for portable emission monitoring measurements.

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 all 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 analyzer 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 of the heated line is 19 m + 1 m with 230 VAC and 9 m + 1 m with 115 VAC power supply. There is also an optional integrated O2 sensor that supplements the capabilities of the Gasmet FTIR gas analyzers.
