A turbidimeter including a sensor apparatus that has a housing with first and second receptacles. An incident light beam is established within the housing by a light source module that is releasably engaged with the first receptacle. A test liquid holder is removably engaged with the first receptacle. A test liquid holder is removably received by the second receptacle for positioning a liquid to be tested in the path of the incident beam. A photodetector or analogous instrument is provided at an angle to the incident light beam for sensing light scattered by the test liquid. An analyzer apparatus includes appropriate circuitry that is responsive to the photodetector for determining the turbidity of the test liquid. The turbidity is then displayed in both graphic and instantaneous alphanumeric form.
