The invention discloses a liquid acidity control instrument. The liquid acidity control instrument comprises electromagnets, gas pipes, a tank body, an iron frame, a funnel, a solenoid valve, a pipe, a gear motor, a support, a casing, a rotation shaft, a controller, a fixing block and a PH acidity tester. The iron frame is installed in the tank body. The outer side of the tank body is uniformly provided with the multiple electromagnets. The pipe is installed below the electromagnets and is uniformly provided with the gas pipes. The funnel is installed on the upper part of the iron frame. The solenoid valve is installed in the funnel. The upper part of the funnel is provided with the fixing block. The fixing block is installed at a side of the rotation shaft. The controller is installed at the other side of the rotation shaft. The tank body is installed at the one side of the rotation shaft and the tank body is installed at the other side of the rotation shaft. The tank body is connected to the pipe. The gear motor is installed below the rotation shaft. The support is installed below the gear motor. A set acidity range value can be burned on the liquid acidity control instrument, the current acidity value and solenoid valve opening / closing cases are displayed on the first line of a display of the controller, the set range value is displayed on the second line and the controller carries out automatic adjustment.
Description
Technical field [0001] The invention relates to a liquid acidity control instrument and a use method, in particular to a control device capable of controlling the liquid acidity and alkalinity within a certain range in a large-scale laboratory environment, belonging to the field of laboratory electronic control devices. Background technique [0002] In order to observe and analyze the changes of various indicators caused by the growth of the acidity of marine organisms, it is necessary to set and control the pH of the seawater in different tanks in a large laboratory, especially if the radius of the pool is more than 10 meters, keep it at Within a certain range of pH, it is generally controlled within the neutral range. Liquid pH is currently manually measured and neutralized reagents are added. Therefore, the efficiency is low, the dosage is uneven, and the accuracy is poor. Therefore, it is an urgent need to solve The problem. Summary of the invention [0003] The purpose of th...
