Description

Water solution oxidation reduction potential value rapid testing device with water pump
Technical Field
The invention relates to the technical field of potential value testing, in particular to a rapid testing device for an oxidation-reduction potential value of an aqueous solution with a water pump.
Background
The Oxidation-reduction potential (ORP) is used for reflecting the macroscopic Oxidation-reduction presented by all substances in a water quality system, the larger the ORP value is, the stronger the Oxidation of the water body is, and the smaller the ORP value is, the stronger the reduction of the water body is;
the existing method for testing the oxidation-reduction potential (ORP) value of an aqueous solution is to directly put an ORP electrode (usually, inert metals platinum and gold are used as an anode, a reference electrode is a saturated calomel electrode or a silver/silver chloride electrode is used as a cathode) into a static aqueous solution for testing, and read the maximum potential value between the cathode and the anode of the ORP electrode as the ORP value of the oxidation-reduction potential of the tested aqueous solution (the observation method is usually to amplify the potential values on the cathode and the anode of the ORP electrode through a circuit and display the potential values on an electronic display screen); if the ions on the ORP electrode are to be removed, the ORP electrode is placed in a static deionized water solution until the display value on the display screen is reduced to the minimum;
in the existing ORP test type, online ORP tests installed in a circulating water path are common in the market, but the online water flow speed is relatively slow, and a portable ORP test pen is also available in the market, the ORP test pen is usually powered by a dry battery or a button battery for carrying convenience, the principle is that the ORP test pen is amplified through a circuit, a display screen displays a test value, the test method is that a test pen electrode is usually inserted into a tested water solution, and the read value is the ORP value of the tested water solution when the ORP value rises to have no change;
the existing devices for testing Oxidation Reduction Potential (ORP) values of aqueous solutions have the following disadvantages:
1. because ions in the measured water solution can form a potential difference after being adsorbed by the cathode and the anode of the ORP electrode, because the water solution is static, the ions in the water solution can be captured after being close to the electrode, the free movement of the ions in the water solution is relatively slow in the static water solution, and the saturated ions are captured by the ORP electrode, namely the time required for obtaining the maximum ORP value is long, so that the test efficiency is low;
2. the ORP electrode is placed in the deionized water solution, ions on the ORP electrode are removed, and the deionized water solution is in a static state, so that the ions are slowly diffused in the water solution freely, namely the ions on the ORP electrode are removed, the required time is long, and the testing efficiency is low.
