Abstract: A turbidity calibration-correction apparatus is configured for an automated calibration-correction of a turbidity. The calibration-correction apparatus includes: a turbidity calibration standard configured for calibration of the turbidity measurement apparatus, a memory configured to store an attribute-value including at least a correction-value that is a function of a turbidity value of the turbidity calibration standard measured by the turbidity measurement apparatus, where the calibration-correction is based on the correction-value, and a communicator configured to transfer at least an identity of the turbidity measurement apparatus and the correction-value from the turbidity measurement apparatus to the calibration-correction apparatus.

Abstract: A system and method for self-calibrating optical turbidity measurements includes a housing comprising a cavity with an inner wall having an essentially straight section and an opening for the medium. An optical standard is moveable between first and second sections within the essentially straight section, and a light source and a light sensor, arranged at the first section and configured to measure the turbidity of the medium, when the optical standard is at the second section, and configured to measure the turbidity of the optical standard and to determine, as a function of the measured turbidity, a calibration coefficient for performing a self-calibration, when the optical standard is at the first section.

Abstract: A method for monitoring a sensor function of a potentiometric sensor that includes: an ion-sensitive electrode including an ion-sensitive glass bulb; a reference electrode assembly including a reference electrode; and an ion-sensing circuit having a first terminal connected to the ion-sensitive electrode and a second terminal connected to the reference electrode, the circuit measuring the potential difference that develops in the loop between the reference and the ion-sensitive electrode. The method includes the steps of: a) injecting a pre-defined electric test current from the ion-sensing circuit into the loop comprising the reference and the ion-sensitive electrode; b) monitoring an additional potential difference that develops in the loop between the reference and the ion-sensitive electrode in reaction to the injection of the test current; and c) determining if the additional potential difference is within an expected range characterizing healthy function of the sensor.
