GAS MIXING DEVICE

Gas mixing devices are used for high precision control of gas mixtures in calibraon procedures and preparing gas mixtures for industrial or laboratory use. Precise diluon of various gases enables the user to obtain most accurate gas mixture for used applicaon. User simply sets the target output concentraon for desired gas. Actual concentraons based on flow measurements are displayed in real me during mixing.

Principles
Various gas sensors combined with high accurate mass flow controllers and Nsophiscated soware mixes the gas mixture from 100% down to 1 ppm.

Applicaons:

  • Gas mixtures for sensors calibraon;
  • Calibraon of personal gas monitors;
  • Calibraon of Emission, Imission monitors;
  • Gas mixtures for industrial, laboratory use;
  • Applicable also in Biotechnology, Pharmacy, Chemical and biological experiments.

Advantages

  • Mixing non-corrosive and corrosive gases such as: SO2, NO, NO2, CL2, H2S, etc;
  • 1 – 4 channels;
  • High accuracy and repeatability;
  • Staonary or portable;
  • Mixtures from 100% to ppm.

Technical specificaons
