Product description
The MESSKO® Gas Quick Test is used to test the gases in the
MESSKO® gas sampler or the Buchholz relay for the presence
of carbon monoxide and hydrogen. No quantitative analysis
of the gases is made.
2.1 Mode of operation
A Y-connector is screwed onto the gas withdrawal valve for
qualitative analysis of the gases in the gas sampler or in the
Buchholz relay. The Y-connector holds two detector tubes for
testing the presence of carbon monoxide and the presence
of hydrogen respectively. After opening the gas withdrawal
valve, the gas contained is routed at an appropriate pressure
(> 0.5 bar) to the outside through the detector tubes and
leads where applicable to their discolouration.
