A NEPHELOMETRIC TURBIDIMETER AND METHOD FOR CONTROLLING THE HUMIDITY OF VENTING AIR IN A NEPHELOMETRIC TURBIDIMETER

摘要

The invention is directed to a nephelometric turbidimeter (10) for measuring a turbidity of a liquid sample (13) in a transparent sample cuvette (12), the turbidimeter (10) comprising a cuvette chamber (16) defined by a cuvette chamber housing (14) wherein the sample cuvette (12) is arranged, and a drying apparatus comprising : a cuvette chamber inlet opening (38) for venting the cuvette chamber (16) and a cuvette chamber outlet opening (42) for deventing the cuvette chamber (16), an air circulator (49) for pumping air from the outlet opening (42) to the inlet opening (38), and a drying body (32) arranged in the drying path between the outlet opening (42) and the Inlet opening (38). This arrangement allows to actively and dynamically control the air humidity within the cuvette chamber (16).
