Question 246Motor Plants - Assistant Engineer

The correct answer is A) comparator type mist detector. This is the correct answer because a comparator type mist detector is a device used to detect the presence and concentration of mist or fog in a system, which is likely what is being depicted in the illustration MO-0008. Comparator type mist detectors work by comparing the opacity of a sample to a known reference, allowing the concentration of the mist or fog to be determined. The other answer choices, such as an exhaust gas vapor condenser, Ringelmann exhaust gas analyzer, or reflective type explosion meter, are not relevant to the illustration and would not be the correct classification for the device shown.
