Blend Cal-gas Standards

The 491M Gas Standards Generator is a modular, versatile system for blending precision gas standards in the lab. The unit is capable of generating concentration ranges from sub-ppb levels to over 50 percent, from pure compounds, using single step dilution. Interchangeable modules allow a variety of techniques to be combined to generate a wide range of mixtures. The mixtures can be binary or multicomponent and supplied dry or humidified.
