Buchholz gas sampler - BGS
System solutions for fault diagnosis

Buchholzgas-Sampler BGS Application

The Buchholz gas sampler replaces the traditional gas samplers on the Buchholz relay. It serves to securely take gas samples from the Buchholz relay.

In the Buchholz gas sampler the gas sample can be stored without its quality being affected until it will be analysed.


  • Gas sampling with the help of the testing valve of the Buchholz relay, no dead space
  • Safe storage of Buchholz gas
  • Safe transport of Buchholz gas
  • Can be combined with the Buchholz gas tester to form a functional unit
  • An oil trap prevents oil from entering the Buchholz gas sampler
