ABSTRACT:
A telescopically collapsible depth gauge-analyzer which has one mode of operation that results in a sample being collected as the device is lowered through a body of the liquid of interest. In a second mode of operation, liquid is not allowed to flow into the device until it reaches the bottom of the body of liquid and an inlet valve in the bottom of the device is opened. The depth gauge-analyzer is equipped with an arrangement which allows the inlet valve to be opened and the collected liquid to be drained from the device without contacting the user. Visual and/or audible indicators make the user of the device aware that the liquid of interest is flowing into it and that the drawing of a sample has been completed.
