Description

Wireless PH value detection equipment

Technical Field

The utility model belongs to the technical field of PH value detection, and particularly relates to wireless PH value detection equipment.

Background

There are two main ways of PH detection in the market. The first is to use a PH paper, and the other is to use a sensor to read the PH.

The PH value is measured by a chemical reaction method by the PH test paper, and the principle is that an object to be measured and the PH test paper generate chemical reaction and the color of the test paper is changed. The PH test paper is a ruler for testing the PH value of the solution, and is also called litmus test paper. The PH test paper is provided with three indicators of methyl red, bromocresol green and thymol blue, and the three indicators can change color according to a certain rule in solutions with different PH values. The PH test paper has very wide application, when the PH value of the solution is tested, a clean and dry glass rod is used for dipping the solution to be tested in the middle part of the test paper, the color after stable change is observed, and the color is compared with a standard colorimetric card to judge the property of the solution. When the pH value of the gas is checked, distilled water is used for wetting the test paper, the test paper is stuck to one end of the glass rod, then the test paper is sent to the vicinity of a container mouth containing the gas to be tested, the color change is observed, and the property of the gas is judged.

The PH detector adopts a sensor for measurement in the market, the principle belongs to a primary battery system, the effect of the PH detector is to convert chemical energy into electric energy, and the terminal voltage of the battery is called electrode potential; this potential is constituted by two half-cells, one of which is called the measurement electrode and the other is called the reference electrode.

Both of these techniques are currently available for PH detection, but have inconveniences in detection. Firstly, the detection of the PH test paper can be concluded after a certain reaction time of the test paper, and the approximate reading of the PH value of the object to be detected can be determined by comparing the colors of the test paper, so that the PH test paper is inaccurate; in addition, the PH detector also needs to obtain relevant values after detecting the object to be detected, the values obtained in the detection process cannot be recorded, certain hysteresis exists in the recorded acquisition when the PH value of the object is fluctuated, and the existing small PH value detector can only be used in a hand-held mode and cannot be used as a fixed PH value detector.
