Products

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.

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.
