HovaGAS XS
The HovaGAS XS is an ultra-compact gas mixer.
It provides the simplest way to flexibly and precisely mix gases for emission measurement system verification, gas chromatograph calibration, and more.
It combines proven mass flow technology with an ultra-compact, portable case design.
The HovaGAS XS is a gas mixer equipped with 2 to 3 mass flow controllers (MFCs).
The automatic calculation of concentrations, gas flows, and their control is managed by the internal central electronics.
Using the device’s built-in gas library, the mass flow controllers can be adapted to the specific gas used.
The HovaGAS XS is available in two variants:
- HovaGAS XS-LD: MFCs have a dynamic range of 1:20, meaning they can operate between 5% and 100% of their measurement range.
- HovaGAS XS-HD: MFCs have a dynamic range of 1:50, meaning they can operate between 2% and 100% of their measurement range.
Please specify the desired variant when making an inquiry.
Reliable
- All flow rates and gas concentrations are traceable
- Independent of inlet pressure, outlet pressure, and temperature
- Displays the achieved gas concentration
User-Friendly
- Compact, portable case design
- Intuitive software for entering desired inlet and outlet concentrations
- No manual calculations required
- Easy generation of variable gas mixtures
- Significant reduction in the number of required test gas cylinders
Versatile
- Suitable for all gaseous components in emissions and air quality monitoring
- Configurable with 2–3 gas channels
The HovaGAS XS-LD is available in the following configurations:
- HovaGAS XS2-LD with 2 mass flow controllers
- HovaGAS XS3-LD with 3 mass flow controllers
The HovaGAS XS-HD is available in the following configurations:
- HovaGAS XS2-HD with 2 mass flow controllers
- HovaGAS XS3-HD with 3 mass flow controllers
The HovaGAS XS is customized to the required operating range, primarily based on the total gas flow needed. Typical ranges are 60 l/h to 600 l/h.
Wherever gas analyzers need to be tested but the required dry test gases are not available in the necessary form, the HovaGAS XS is used for test gas mixing and dilution:
- In emissions monitoring for verification and calibration, such as testing oxygen analyzers
- For adjustment and linearity control of MEMS gas sensors, such as NDIR CO2 sensors or VOC sensors
- For generating extremely low concentrations that are not available in test gas cylinders, such as NOx concentrations in the ppb range
- Kalrez® seals for use with corrosive gases
viewGAS XS Software
The HovaGAS XS is operated via the viewGAS XS software using a notebook or PC. The intuitive interface allows input of total gas flow as well as inlet and outlet concentrations.
All measurement data is recorded and stored, and time-dependent concentration profiles can be created and executed. The software also enables customization of the HovaGAS XS gas library.
