Description

TECHNICAL FIELD

[0001] The utility model relates to automatic instrument measurement technical field, concretely relates to a high temperature particulate impurity aqueous solution pH value measuring device. BACKGROUND

[0002] The pH meter is a commonly used measuring instrument, mainly used for measuring the hydrogen ion concentration in the liquid, obtaining the value of acidity, neutrality or alkalinity, and applied to the sewage treatment in the industrial production process for environmental protection management, therefore, the pH value measurement of the aqueous solution is one of the most important physicochemical parameters in industrial production. Most of the electrodes used with the pH meter adopt composite electrodes, i.e. measuring electrodes and reference electrodes. The hydrogen ion activity in the measured liquid acts between the two electrodes to generate a potential difference, which is related to the specific ion activity and communicates with the measuring solution. The pH value of the measuring solution is reflected through the measuring instrument. The composite electrode is generally made of thin film glass, so it is easy to be damaged when the measuring solution temperature is high or contains particulate impurities, resulting in a high damage rate of the pH meter. At present, when measuring the pH value of the solution, a hole is generally opened on the discharge pipeline, and the composite electrode is directly inserted into the measured liquid to measure the pH value of the solution. When the temperature of the measured solution is high or contains particulate impurities, the composite electrode is easily damaged, so the pH meter has a high damage rate in the industrial sewage measurement process. Not only does it increase the procurement cost, but also the maintenance personnel need to enter the acid and alkali, toxic and harmful working environment frequently, which easily causes the increase of the operation danger of the equipment maintenance personnel and is not conducive to safety production.
