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 VOCs, 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 measurements 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 analyzer and does the actual analysis of the results.
- Laptop PC with CalcmetTM software: RS232 communication to control DX4015
- Power connection 12 VDC: 12 V cables with battery clips or cigarette lighter connector
- Particulate filtration and heated/unheated lines for gas transport
- Optional analog signals in external PC: ADAM 5000/TCP module (for analog inputs, outputs, relays)
- Optional wheeled cart for the analyzer and laptop computer
- Highest possible sensitivity for low detection limits
- Built-in pump
- Also for high humidity applications due to heated sample cell
