Abstract: A hydrometer for determining coolant fluid antifreeze concentration includes a housing having a pair of spaced openings for inflow and outflow of coolant fluid into and from the housing, a transparent view dome mounted in flow communication with the housing, a pair of identical sets of float balls of different specific gravities, a pair of longitudinal channels defined along opposite portions of the view dome in flow communication with the interior thereof and containing the sets of float balls for longitudinal movement relative to the view dome and for visual observation from the exterior of the view dome, and a dam defined in the housing between and spaced from the flow openings thereof and capable of obstructing the path of coolant fluid flow directly between the openings of the housing so as to cause deflection of coolant fluid flow into the transparent view dome and the channels therein.
