Description
Gasmet™ DX4015 is a portable FTIR gas analyzer for ambient air analysis. The key features of the Gasmet™ DX4015 include a high sensitivity sample cell for lowest possible detection limits and a built-in-pump, which means that there is no need to use a separate sampling system.
Gasmet™ DX4015 is typically set-up to measure a variety of different gases, including VOC´s, acids, aldehydes, and inorganic compounds such as CO, CO2 and N2O. Up to 50 compounds can be measured simultaneously. Gasmet™ DX4015´s sample cell is heated to 50 °C, which allows measurement to be done in conditions where high humidity is expected.
The Gasmet™ DX4015 is operated with an external portable laptop that runs the Calcmet™ software. This easy-to-use program both controls the analyser and does the actual analysis of the results.
SYSTEM PARTS
- DX4015
- Laptop PC with CalcmetTM software: RS232 communication to control DX4015
