Description

Portable acidimeter

Technical Field

The utility model relates to a check out test set technical field especially relates to a portable acidimeter.

Background

The acidimeter is also called pH meter, and is used for measuring the pH value of solution. The principle of the galvanic cell is used for working, and the electromotive force between two electrodes of the galvanic cell is related to the properties of the electrodes and the hydrogen ion concentration in the solution according to the Nernst law. There is a corresponding relationship between the electromotive force of the primary cell and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value. The acid-base meter is a common analytical instrument and is widely applied to the fields of agriculture, environmental protection, industry and the like. Soil pH is one of the essential properties of soil that are important. Factors such as the temperature and ionic strength of the circulating solution should be considered in the pH measurement process. The existing acid-base meter generally has the following problems: the support frame occupies a large space and is not convenient to carry.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural view of an embodiment of a portable acidimeter according to the present invention in use; fig. 2 is a schematic structural diagram of an embodiment of a portable acidimeter according to the present invention when not in use.

A portable acidity meter comprising: the device comprises a shell 1, electronic components (not shown), a support 2, a detection pen 3, a data line 4, a display screen 5 and a control button 6.

The upper surface of the housing 1 is formed with a mounting groove 11 for accommodating the holder 2 and the sensing pen 3. The depth of the mounting groove 11 is deep enough so that the holder 2 and the test pen 3 do not protrude out of the mounting groove 11 when they are placed in the mounting groove 11. Electronic components are built into the housing 1 as necessary functional components for detecting acidity, and are well known to those skilled in the art, and therefore, they are not described herein. The shell 1 is also provided with a display screen 5 and a control button 6, and is in data connection with the internal electronic components. Respectively used for displaying the numerical value of the detected sample and controlling the portable acidimeter.

The bracket 2 includes a first connecting plate 21, a second connecting plate 22, a sleeve 23, and a spring 24. One end of the first connecting plate 21 is rotatably connected with one end of the bottom of the mounting groove 11, and the other end is rotatably connected with one end of the second connecting plate 22. A holding groove is formed at the other end of the second connecting plate 22, so that the second connecting plate 22 is of a U-shaped structure. The lateral wall of sleeve 23 is connected with the holding tank rotation to the cover is established on detecting pen 3. The spring 24 is also sleeved on the detection pen 3, one end of the spring is connected with the detection pen 3, and the other end of the spring is connected with the sleeve 23. The sleeve 23, the spring 24 and the test pen 3 are coaxially arranged. The detection pen 3 penetrates through the shell 1 through the data line 4 to be connected with an electronic component inside the shell 1, and data detected by the detection pen 3 are transmitted to the electronic component for processing.

When the device is not used, the sleeve 23 is rotated to enable the sleeve 23, the spring 24 and the detection pen to enter the accommodating groove and be located on the same horizontal plane with the second connecting plate 22, then the first connecting plate 21 and the second connecting plate 22 are rotated and placed into the installation groove 11, and in order to prevent the second connecting plate 22 from protruding out of the installation groove 11, the depth of the installation groove 11 is preferably larger than the sum of the thicknesses of the first connecting plate 21 and the second connecting plate 22.

When the portable acidity meter is needed to be used, the first connecting plate 21 and the second connecting plate 22 are pulled out from the mounting groove 11, so that the first connecting plate 21 is vertical, and the second connecting plate 22 is horizontal. And the sleeve 23 is rotated such that the sleeve 23 is vertically disposed perpendicular to the second connecting plate 22. The test sample to be detected is placed below the detection pen 3, then the detection pen 3 is pressed, the spring 24 is compressed, and the detection part UR at the lower end of the detection pen 3 is placed in the test sample to be detected, so that the detection can be completed. And reads the corresponding value from the display 5.

Implement the embodiment of the utility model provides a, following beneficial effect has: the utility model discloses a portable acidimeter is through setting up first connecting plate and second connecting plate, rotates with the second connecting plate through first connecting plate to place the mounting groove in, set up the holding tank simultaneously on the second connecting plate, rotate test pen in the holding tank, can place the support in the mounting groove with test pen when not using, in order to reduce the volume, conveniently carry.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
