High-reliability pH tester and using method thereof

Abstract

The invention provides a high-reliability pH tester and a using method thereof, and aims to solve the technical problem of accurately measuring the pH value of solid meat. The tester comprises an acidity testing device, a displayer, a controller and a temperature compensation device, wherein the acidity testing device and the temperature compensation device each comprise an inserting tube mechanism and an inner pushing tube mechanism, the acidity testing device further comprises a test electrode mechanism, and the temperature compensation device further comprises a temperature testing mechanism. The acidity testing device is used for testing the pH value of pork and other fresh meat solid samples, and the temperature compensation device is used for detecting the temperature of pork and other fresh meat solid samples and can compensate the deviation, caused by infection of the temperature, of the tested meat samples. The controller is electrically connected with the displayer and used for receiving signals of the acidity testing device and the temperature compensation device and transmitting the processed signals to the displayer to be displayed. The high-reliability pH tester has the advantages of improving the accuracy of detecting the acidity pH value of the meat samples.

Description

technical field [0001] The invention relates to the technical field of acidity meters, in particular to a high-reliability pH meter and its usage method. Background technique [0002] Acidity meters are often used to measure the pH value in liquids. For the determination of the pH of solid samples of fresh meat such as pork, the meat is usually pulled apart with a knife, and then the probe of the pH electrode is inserted into the opened meat. Since the cut meat cannot be in close contact with the probe, the operator needs to squeeze the meat by hand. Because the gap is in contact with the outside world, a large amount of oxygen-containing substances in the meat such as oxyhemoglobin and myoglobin are inevitably oxidized, which affects the change in the potential difference of the liquid in the meat, resulting in inaccurate measurement results. When the meat is manually squeezed, the meat is deformed, and different substances in the cytoplasm flow out, which will also affect...
