Abstract
There is disclosed a method and apparatus for repetitively taking samples of a predetermined quantity of a test gas in a liquid and introducing these samples to a test chamber. Each sample is agitated to release therefrom the test gas. The released gas is then conveyed to a sensor, which monitors the released gas for the presence of a concentration above the threshold level to produce an alarm indicative thereof. The samples of the test gas in a liquid may be repetitively taken from one zone of a plurality at a time until each zone is sampled. After one sample has been tested in the test chamber, it is discharged therefrom and the test chamber is flushed with a sample of the liquid and test gas taken from the next zone of the plurality before introducing the next sample from the same, next zone.
