摘要： The invention refers to an electrochemical process measurement arrangement (10) with a process sensor unit (30), the sensor unit (30) comprising a reference electrolyte tank (50) with a reference electrolyte liquid (52) and a reference electrode (54), and a measurement electrolyte tank (60) with a measurement electrolyte liquid (62), a measurement electrode (64), a gas-selective membrane (90) separating the reference electrolyte liquid (52) from a sample liquid (13') and a pressure balance channel (84) fluidically connecting the tank interior (56) with the atmosphere (11).
The pressure balance channel (84) is defined by a balance channel body (80) made of a hydrophobic material having a contact angle Theta higher than 90°.
This allows to realize a very narrow pressure balance channel without the danger of being clogged by electrolyte droplets, so that the evaporation loss of the measurement electrolyte is significantly reduced.-

摘要： A nephelometric turbidimeter for measuring a turbidity of a liquid sample in a sample cuvette. The nephelometric turbidimeter includes a measurement light source configured to emit an axial parallel light beam directed to the sample cuvette, a scattering light detector arranged to receive a scattered light from the sample cuvette, and a diffuser comprising a diffuser body and a diffuser actuator. The diffuser actuator is configured to move the diffuser body between a parking position in which the diffuser body does not interfere with the axial parallel light beam and a test position where the diffuser body is arranged between the measurement light source and the sample cuvette so that the diffuser body interferes with the axial parallel light beam and generates a diffuse test light entering the sample cuvette.

摘要： Disclosed is a process photometer arrangement (10) with a photometric cuvette unit (20) comprising a cuvette body (24) defining a cuvette cavity (25) and a combined sample inlet/outlet opening (34), a photometer light inlet window (60) and a photometer light outlet window (62). The cuvette body (24) is movably supported by a cuvette body support element (88) and the cuvette unit (20) is provided with a cuvette vibration device (80) for vibrating the cuvette body (24) to thereby quickly and homogenously mix a liquid sample volume (31) within the cuvette cavity (25) without any separate mixing element within the cuvette cavity.
This allows a short mixing action within a microfluidic cuvette.-
