Digital Multichannel Gas Mixer

The digital multichannel gas mixer is a universal, portable device that allows the user to generate arbitrary mixtures of gases of their choice.

The device operates fully automatically; only the selected gases and electrical power need to be connected. Premixed gases are expensive and not easily accessible. ExVA gas mixers enable users to control flow rates, concentration, and time-based mixing from various gas sources according to their own needs. These gas mixers provide flexibility that standard gas cylinders simply cannot offer.

They offer a quick solution for applying, monitoring, measuring, and creating gas mixtures or dilutions. Modern software allows access and control of every parameter, enabling the regulation of concentration, quantity, and precise mixing duration.

  • ExVA Ltd. have been an excellent support in the explosion proof certification process of our BlueEye™ Ex-D combustible gas analyzer. Nagy and his team have supported us with solutions to the technical challenges rather then just pointing out what isn`t possible. All this in a very efficient way, allowing us short time to market whilst avoiding unnecessary cost. We can highly recommend to use ExVA`s services.

    Bart Riemens – CEO, Bright Sensors SA
  • Throughout the many years of our cooperation with ExVA, we have always been impressed with the unusually high level of preparedness among their personnel. They have been happy to help us in the certification process of all our products.

    Miklós Kovács – CEO, Szerver Szektor Kft.
  • We have worked with ExVA Kft. and their predecessor (BKI) since 1992. Over the past nearly 30 years, they have completed several dozen type-test certifications for us. They provide high-standard professional support for the design phase of the equipment our Company manufactures for use in potentially explosive environments and for conducting their testing according to the requirements of the latest EU Directive, as well as for the proper functioning of our production quality assurance.
