Description

Double tank type acid-base detector

The new model relates to an electrochemical detector, especially an acid-base detector.

In aquaculture, animal husbandry, laboratories and other applications, it is often necessary to measure the pH of water or chemical solutions to grasp the water quality and the properties of the solution. At present, there are a number of acid-base detectors that can be used to measure the acid-base value of a solution and display the value of the acid-base value on its screen. However, the existing acid-base detectors are different in the form of their measuring terminals, so that they can only be applied to limited use occasions. When the multiple detection requirements of the same sampling occasion cannot be affected by the function of a single acid-base detector When it is satisfied, it is necessary to carry acid-base detectors of different specifications for testing, which lacks convenience in use and increases the cost of purchasing additional acid-base detectors.

One of the objectives of the present invention is to provide an acid-base detector that can be used in a variety of applications.

In order to achieve the above and other objectives, the present invention provides a double tank type acid-base detector, which includes a housing, a processor, a memory, a display unit, an input unit, a first detection slot and a second Detection slot. The processor, the memory, the display unit, the input unit, and the first and second detection slots are all provided in the housing. The memory, the display unit, the input unit, and the first and second detection slots are all electrically connected to the processor, and the memory The body stores a first detection formula and a second detection formula that is different from the first detection formula. The first detection slot is matched with the first detection formula, and the first detection slot is for inserting a first detection element. Form an electrical connection with each other; the second detection slot is matched with the second detection formula, and the second detection slot is for a second detection element to be plugged in to form an electrical connection with each other. The input unit is for the user to input a selection instruction for selectively activating at least one of the first and second detection slots, and the processor is used to activate at least one of the first and second detection slots according to the selection instruction. The open circuit potentials of the first and second detection elements inserted in the activated first and second detection slots are measured, and the post-processor is further based on the paired with the activated first and second detection slots. The first and second detection formulas convert the open circuit potential into a pH signal, and display the pH signal on the display unit.

The new model provides two detection tanks with different detection formulas, so that different detection elements can be applied to the new acid-base detector, thereby increasing the applicable occasions of the new acid-base detector and meeting the diverse needs of users , And can reduce the cost derived from purchasing a variety of specifications of acid-base detectors.

Please refer to Figures 1 to 3, the ones shown are the multiple use occasions of the first embodiment of the new double tank type acid-base detector (hereinafter referred to as the acid-base detector). Please also use Figure 4. The acid-base detector includes a housing 10, a processor 20, a memory 30, a touch screen 40, a first detection slot 50 and a second detection slot 60. The control screen 40 includes a display unit 41 and an input unit 42 layered on the display unit 41. Among them, the processor 20, the memory 30, the display unit 41, the input unit 42, the first detection slot 50 and the second detection slot 60 are all provided in the housing 10, and the memory 30, the display unit 41, the input unit 42, the second Both a detection slot 50 and a second detection slot 60 are electrically connected to the processor 20.

The processor 20 is, for example, a programmable logic controller (PLC). The memory 30 stores a first detection formula and a second detection formula that is different from the first detection formula. The first and second detection slots 50, 60 is for the first and second detection elements 70 and 80 to be plugged in to form an electrical connection with each other.

Because in the acid-base detection operation of the acid-base detector, the open circuit of the detection element and the pH value of the solution to be tested usually change linearly or other regular changes, so the measured open circuit can be measured through the first detection formula The potential is converted into a pH value. On the other hand, since the resistance of different detection elements is not the same, the relationship between the open circuit and the pH value is also different from each other. Therefore, in possible non-limiting applications, the difference between the first and second detection formulas may be It lies in the difference of the slope correction coefficient, or the slope between the two is the same but a fixed value must be added or subtracted. Therefore, the user can set two different detection formulas to make a single acid-base detector suitable for two different specifications of detection elements at the same time, while avoiding the errors that may be derived from the two specifications, thereby improving its versatility. Meet the needs of multiple use.

For example, in this embodiment, the first detection element 70 has a plug-in end 71, a detection end 72, and a wire 73 electrically connected between the plug-in end 71 and the detection end 72, and is a wire-type detection element. The plug-in end 71 is for plugging into the first detection tank 50, the detection end 72 is for immersing in a solution to be tested, and the detection end 72 has at least one electrode for electrochemical reaction with the solution to be tested, so that the lead The type detection element can be applied to the occasions where the pH value of the solution to be tested is continuously monitored, such as the occasion of configuring laboratory medicines.

On the other hand, the second detection element 80 is an acid-base detection test strip, which has a gold finger 81, a sensing area 82, and a plurality of electrodes extending between the gold finger 81 and the sensing area 82. The gold finger 81 It can be inserted into the second detection groove 60, and the electrodes are exposed in the sensing area 82 for contact with a solution to be tested. For example, the user can drop a water sample or other solution sample on the sensing area 82 to make The electrode can be in contact with the water droplets, and then the gold finger 81 can be inserted into the second detection slot 60 to perform acid-base detection operations.

The touch screen 40 has a user interface displayed on the display unit 41, the user interface has a selection function area 411, and the input unit 42 allows the user to input selection commands by clicking on a position corresponding to the selection function area 411. For example, the user can choose to individually activate the first sensing slot 50 (as shown in Figure 1), individually activate the second sensing slot 60 (as shown in Figure 2), or simultaneously activate the first and second sensing slots. Measuring grooves 50, 60 (as shown in Figure 3). In the case where both the first and second sensing slots are activated, there may be two independent pH display areas on the user interface to display the pH of different solutions to be tested. For example, the user interface of this embodiment Including a dynamic cursor system and a numeric pH display area, which can independently display the pH value.

The use method in which the first and second sensing slots 50 and 60 are activated at the same time can be applied to more complex detection occasions. For example, in a cancer cell growth experiment, the glucose nutrient in the DMEM medium will be rapidly consumed when the cells grow, and the metabolized product will make the culture environment acidic. Therefore, the first detection element can continuously monitor the pH of the culture environment. To determine whether the medium needs to be replaced; at the same time, the pH value of the newly added medium should also be confirmed to avoid the risk of deterioration and contamination, and simultaneously observe whether the culture environment after the replacement matches the pH value of the added medium. The second detection element can be used to sample the newly added culture medium and determine the pH value. In this way, it is possible to simultaneously monitor the cell culture environment and whether the newly added medium has a pH change, which is a more complicated use occasion. For another example, in hydroponic vegetable cultivation, the pH value of the vegetable cultivation tank must be controlled to meet the conditions for vegetable growth. At this time, when adding new fertilizers, the pH value of the added liquid fertilizer must also be measured separately to avoid damage The pH value of the vegetable growing environment. At this time, the pH value of the culture tank can be continuously monitored by the first detection element, and the pH value of the liquid fertilizer can be measured by the second detection element, so as to meet the needs of hydroponic vegetables.

In summary, the present invention provides two detection tanks with different detection formulas, so that different detection elements can be applied to the new acid-base detector, thereby increasing the applicable occasions of the new acid-base detector and satisfying users Diversified needs, and can reduce the cost of purchasing a variety of specifications of acid-base detectors.
