The invention is directed to a nephelometric process turbidimeter (10) for measuring a turbidity of a liquid sample (19). The turbidimeter (10) comprises: a transparent sample vial (20) and a separate vial head (30), both defining a sample volume (18) for the liquid sample (19), wherein the lateral inner surface (22, 32) of the sample volume (18) is cylindrical, a sample inlet opening (40) through which the liquid sample flows into the sample volume (18) and a sample outlet opening (50) through which the liquid sample flows out of the sample volume (18), both openings (40, 50) being provided at the vial head (30), and the sample inlet opening (40) being arranged at the cylindrical surface (32) of the vial head (30) and being arranged axially closer to the sample vial (20) than the sample outlet opening (50). The inlet opening axis (a) of the sample inlet opening (40) is inclined with respect to the inlet cross plane (h) with a inclination angle (A2) of 10° to 80° and is angled with respect to the radius (r) with a tangancy angle (A1) of more than 15°. |
