Embodiment Construction

[0012] Such as figure 1 As shown, the detection device for the liquid pH value includes a detection sensor 1 and an ammeter 4; the detection sensor 1 is composed of a positive electrode 2 and a negative electrode 3. The positive electrode 2 of the detection sensor is made of a metal with relatively weak metal activity. The negative electrode 3 of the detection sensor is made of metal with relatively strong metal activity. The positive and negative poles of the detection sensor 1 can be selected from magnesium, aluminum, manganese, zinc, chromium, iron, nickel, tin, lead, copper, silver, platinum, gold and other metals according to their metal mobility. The materials are used as positive and negative electrodes respectively.

[0013] The anode and cathode of the detection sensor are plate-shaped parallel electrodes. The surface area of ​​positive and negative electrodes can be 0.5cm respectively 2 -3cm 2 , 0.5cm-3cm apart. In addition, the positive and negative electrodes...

Abstract

A liquid pH value detection device comprises a detection sensor and an ammeter, wherein the detection sensor comprises an anode prepared from a metal with weak metal activity and a cathode prepared from a metal with strong metal activity, the anode of the detection sensor, the ammeter and the cathode of the detection sensor form a series circuit, the anode and cathode of the detection sensor contact with the liquid to be detected and the corresponding pH value of the liquid is shown on the index plate of the ammeter. The liquid pH value detection device has simple structure, small volume and fast measurement, has no power supply and can measure or judge the pH value of the liquid quantitatively and qualitatively at any time.

Description

technical field [0001] The invention relates to a pH value detection device, in particular to a liquid pH value detection device. Background technique [0002] pH value is one of the most important physical and chemical parameters of aqueous solution, and it is a scale of hydrogen ion activity in solution. In daily life, we often need to know or judge the pH value of liquid. In environmental protection work and aquaculture, we often need to Observe the pH value of the water body. In agricultural production, it is also necessary to measure the pH value of the soil, so as to adjust according to the pH value of different crops or flowers and trees, and adapt to their growth needs. However, the pH value detectors currently on the market are professional measuring instruments, which are bulky, expensive, complicated to operate, and not suitable for popularization. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the obj...
