Gasmet DX4000 has established itself as a trusted partner for hundreds of stack testers and emission researchers. Top professionals rely on its portable nature and the ability to simultaneously measure and detect all key emission components.

World’s Smallest FTIR Emissions Monitoring System​

Gasmet DX4000 is a portable FTIR gas analyzer for applications where multiple gas compounds need to be accurately monitored in hot & humid sample gas. It is the world’s smallest FTIR emissions monitoring system.​  The DX4000 is typically set up to measure H2O, CO2, CO, NO, NO2, N2O, SO2, NH3, CH4, HCl, HF and different VOCs and can measure up to 50 gases simultaneously. Additional gases can be easily added without any hardware changes. The corrosion-resistant sample cell is heated to 180 °C, which ensures that the sample stays in the gaseous phase even with high concentrations of H2O or corrosive gases.​

​The DX4000 is operated with the Calcmet software running on a laptop computer. Calcmet provides a flexible and easy to use UI with all the tools needed for making demanding measurements in a single software.

MCERTS certified​

The Gasmet DX4000 has received the coveted MCERTS certification for stack emissions monitoring.​

A study compared alternative methods (AM) to the European standard reference method (SRM) EN 14791 for measurements of SO2 in emissions. Gasmet’s DX4000 was compared to the Standard Reference Method for SO2 (EN 14791) in order to verify whether it could be used as an alternative method (AM) to EN 14791. The data from test measurements, conducted according to EN 14793, demonstrated that the tested alternative methods, including FTIR, could be used instead of the standard reference method EN 14791.​


Paired with Portable Sampling System​

The DX4000 is designed to be used with the Gasmet PSS portable sampling system. This system utilizes the hot-and-wet measurement principle (no drying or dilution), which ensures that the analysis is done with a representative sample. There is two-stage particulate filtration: the first one in the sampling probe and the second one in the sampling system.​ The portable sampling unit can be optionally equipped with a ZrO2 sensor for accurate oxygen measurement.
