For over 20 years, ExVA Kft has manufactured custom and in-house developed specialised test equipment that are indispensable for carrying out explosion proofing tests. The professional quality of these equipment is demonstrated by our decades long track record of not a single customer having requested any warranty repairs. In order to be able to keep providing the highest quality to our customers, our products are subject to continuous improvement.

Dust chamber

Last year, we produced an IP dust ingress test rig for testing the IP5X, IP6X and IP5K, IP6K grades of the applicable standards (EN/IEC 60529; EN/IEC 60034-5; EN/IEC 60598-1; ISO 20653).


Spark Test Apparatus

The spark test apparatus can be used to inspect whether there are any sparks with sufficient energy within a given circuit to ignite the surrounding explosive environment present. This test is intended to analyse whether, during operation, the tested equipment has the capacity to cause any sparks or arcing that would – under the given conditions – set off an explosion of the standard-specified gas mixture inside the given chamber.


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.



  • We are completely satisfied with the work of the ExVA team. We carry out several joint works with them and they have always been willing and helpful in responding to our inquiries. The work is always done on time and with professional precision. They are immediately available for any questions that may arise and will be answered constructively.

  • 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.
