The Buchholz gas sampler provides a safe method of taking and transporting gas samples from the Buchholz relay or the gas sampling device.

The the assay is hermeticall sealed from the ambient-air by the integrated back-pressure valve. The gas can be kept for up to 5 days in the sampler without exhibiting any impermissible changes in its composition.

Insulation liquid entry into the sampler will be prevented by the oil trap included in the scope of supply.

The sampler has a useful volume of 100 ml. For analysis directly on site with the Buchholz gas tester BGT only 65 ml of the failure gas are needed. The gas remaining can be used for detailed laboratory testing if needed.
