Description

Title of the invention: System for monitoring the evolution of at least one characteristic of a reactive mixture in a container.

[0001] The present invention relates to a system for monitoring the evolution of at least one characteristic of a reactive mixture in a container.

[0002] Such systems are for example used in a teaching context allowing pupils or students to implement measurement systems, in particular electrochemical systems, for the evolution of reactive mixtures.

[0003] In these applications, the readings are taken manually, with the students being asked to record the changes in the characteristics of the mixtures on paper tables.

[0004] But this presents a certain number of disadvantages, particularly in terms of automation, reliability and speed of readings and the delivery or restitution of information.

[0005] The aim of the invention is therefore to solve these problems.

[0006] To this end, the invention relates to a system for monitoring the evolution of at least one characteristic of a reactive mixture in a container, characterized in that it comprises: - means for adding at least one reactive agent to the mixture in the container; - means for measuring the quantity of reactive agent added; - means of recording the evolution of the characteristic of the mixture in the container; - means of relating the evolution of this characteristic as a function of the quantity of agent added; and - means of providing information relating to this development.

[0007] According to other characteristics of the system according to the invention, taken alone or in combination: - the means for measuring the quantity of reactive agent added comprise means in the form of a dropper; - the characteristic whose evolution is noted is a characteristic chosen from the group including in particular the pH and / or the conductivity of the mixture; - the means of delivering the progress information are chosen from the group including in particular means of displaying and / or means of printing a graph illustrating them.

[0008] The invention will be better understood with the aid of the following description, given solely by way of example and with reference to the appended drawing, in which: - [Fig.l] [Fig.l] represents a block diagram illustrating the structure and operation of a tracking system according to the invention.

[0009] This figure in fact illustrates a system for monitoring the evolution of at least one characteristic of a reactive mixture in a container.

[0010] In this figure, the container is designated by the general reference 1 and consists of any suitable container.

[0011] This is for example placed on a support base designated by the general reference 2.

[0012] The mixture in the container is designated by the general reference 3 in this figure.

[0013] The container is associated with means for adding at least one reactive agent to this mixture in this container.

[0014] These addition means are designated by the general reference 4 in this figure and comprise for example a pipette designated by the general reference 5, associated with at least one reservoir for storing reactive agent to be added, this reservoir being designated by the general reference 6.

[0015] Any type of reservoir and any type of reactive agent can be considered.

[0016] It will also be noted that means for measuring the quantity of reactive agent added to the reservoir are provided.

[0017] These means are designated by the general reference 7 in this figure and include, for example, means forming droppers or the like.

[0018] Any means of measuring the added quantity, whether using droppers, flow measurement, etc., can be considered.

[0019] Thus, a reactive agent and in particular a quantity of reactive agent is introduced into the mixture in a regular manner.

[0020] The system according to the invention also comprises means for recording the evolution of a characteristic of the mixture in the container.

[0021] These means of recording evolution are designated by the general reference 8 in this figure.

[0022] These recording means may, for example, be means for recording a characteristic chosen from the group comprising the pH and / or the conductivity of the mixture.

[0023] Of course, other characteristics can be envisaged.

[0024] These means for measuring the quantity of reactive agent added and for recording the evolution of the characteristic of the mixture are connected to means for relating the evolution of this characteristic as a function of the quantity of agent added.

[0025] These means of establishing a relationship are designated by the general reference 9 in this figure and include, for example, any appropriate calculator making it possible to establish a relationship between the evolution of the characteristic and the quantity of agent added.

[0026] These means include, for example, any suitable computer of the programmed microprocessor type, etc.

[0027] These means of connection are then associated with means of delivering information relating to this development, these means of delivery being designated by the general reference 10 in this figure.

[0028] These means comprise, for example, means chosen from the group comprising means for displaying information designated by the general reference 11 or means for printing a graphic illustrating this information, designated by the general reference 12.

[0029] Of course, other means and other forms of embodiment of these different means can be envisaged.

[0030] It is therefore understood that such a structure presents a certain number of advantages in terms of automation and simplicity provided to users.
