Abstract: An apparatus for measuring a water-quality parameter of a liquid sample. The apparatus includes: at least one water-quality parameter sensor selected from the group containing: a chlorine sensor; a turbidity sensor; a conductivity sensor; a pH sensor; a temperature sensor; a pressure sensor; a redox sensor; and a flow sensor; a controller configured to control operation between an active mode, a sleep mode, and a turbo-mode; and an energy source management module associated with the controller. The management module manages voltage in the controller and provides for extended power and low electricity consumption.

Abstract: A method for measuring turbidity, chlorine content and color of a liquid, the method including retaining, from a continuous flow of the liquid, a sample volume of the liquid, and at least nearly simultaneously executing at least two of detecting illumination from the sample volume of liquid by at least a first detector operable for detecting illumination from the sample volume of liquid at a 90-degree angle with respect to an illumination beam generated by an illuminator and impinging on the sample volume of liquid, thereby measuring a turbidity of the sample volume of liquid.

Abstract: A method for measuring turbidity and chlorine content of a liquid. The method includes shaking the liquid in a sample holder, using a shaker assembly, and removing bubbles including micro bubbles from the liquid using the micro-bubble removing shaker, retaining a sample volume of the liquid, and at least nearly simultaneously executing at least two of detecting illumination from the sample volume by a first detector operable for detecting illumination from the sample volume at a 90-degree angle with respect to an illumination beam generated by an illuminator and impinging on the sample volume, thereby measuring a turbidity of the sample volume, detecting illumination from the sample volume of liquid by a second detector operable for detecting illumination from the sample volume of liquid at a 180-degree angle with respect to the illumination beam, thereby measuring chlorine content of the sample.

Abstract: The invention relates to a spectrophotometric measuring cell, useful for automated reagent mixing and for handsfree physical cleansing comprising: a measuring cell; a shaker; and an actuator. The invention also relates to a method for automatically mixing of fluids and/or reagents and for handsfree physical cleansing of the inner core of spectrophotometric measuring cells.
