ECHO Gas Mixing Device
ECHO Gas Mixing Device is available in stationary or portable form for precise dilution and control of gas mixtures.
ECHO precision gas mixing system for sensor calibration
The user enters the target concentration, while the system controls mass-flow controllers and displays calculated concentrations in real time. It supports non-corrosive gases and, in dedicated configurations, corrosive gases such as SO₂, NO, NO₂, Cl₂ or H₂S.
Key benefits
- 1–4 channels and portable or stationary configurations
- Mixtures from 100% down to ppm levels
- High-accuracy, repeatable mass-flow control
- Corrosive-gas compatibility in suitable configurations
- Direct target-concentration setting and real-time display
Applications
- Calibration of sensors and personal gas detectors
- Calibration of emission and ambient monitors
- Gas-mixture preparation for laboratory and industry
- Biotechnology, pharmaceutical, chemical and biological experiments

Frequently asked questions
Can it handle corrosive gases?
Yes. Gases such as SO₂, NO₂, Cl₂ or H₂S require compatible materials and a configuration defined during quotation.
Can it support accredited calibration?
The manufacturer positions it for such applications; method, gas traceability and uncertainty must be validated by the laboratory.
What flow range is available?
Ranges from 0–10 sccm to 0–50 slpm are stated and selected per channel.
