ph acid-base tester

With the vigorous development of the national economy, the path of industrial development at the expense of the environment is unsustainable, and the government has also strengthened environmental protection requirements and monitoring. This involves many parameters that need to be tested, such as acid-base PH, dissolved oxygen, ORP, etc. So the editor will share with you today on PH. So the question is, what is the pH value? How to detect the pH value? 　　 As we all know, the pH value is used to indicate the solution with a very small H concentration ([H] is between 1～10-14mol/L). The index of sexual strength is equal to the negative logarithm of hydrogen ion concentration in value: pHu003d-lg[H]. This method of indicating the acidity and alkalinity of the solution is particularly convenient for solutions with a small [H]. For example, [H]u003d10-9mol/L alkaline solution, its pHu003d-lg10-9u003d9. 2. pH<7, the solution is acidic. The lower the pH, the greater the acidity and the lower the alkalinity. pH>7, the solution is alkaline, the greater the pH, the greater the alkalinity and the less acidity. pHu003d7, the solution is neutral. When the [H]>1mol/L of the solution, [H] is generally used instead of pH to indicate the acidity and alkalinity of the solution. The pH value of the solution is usually measured with an acid-base indicator and pH test paper. The most accurate method is to use a pH meter. The acidity and alkalinity of the solution can also be expressed by the negative logarithm of [OH-] in the solution, that is, pOHu003d-lg[OH-]. At 25°C, the ion product of water is Kwu003d1×10-14, from which it can be deduced that pHpOHu003d14. The pOH value can be calculated from the pH value. pOH<7 is an alkaline solution, pOHu003d7 is a neutral solution, and pOH>7 is an acid solution.　　PH scoring experimental and online 　　traditional: According to the needs of production and life, people have scientifically researched and produced many types of acidity meters: 　　according to the measurement accuracy 　　 can be divided into 0.2 level, 0.1 level, 0.01 level or higher accuracy.　　According to the volume of the instrument, there are pen type (mini), portable, desktop, and online continuous monitoring and measurement. According to the requirements of use, the pen type (mini) and portable pH meter are usually brought to the site for testing and use.　　The accuracy level of the pH meter is selected according to the accuracy required for the user's measurement, and then various shapes of pH meters are selected according to the user's convenience.　　On-line: On-line pH tester is a highly intelligent on-line continuous monitor, which consists of a sensor and a secondary meter. It can be equipped with three-composite or two-composite electrodes to meet various applications. Equipped with pure water and ultrapure water electrodes, it can be applied to the pH measurement of water with conductivity less than 3μs/cm (such as chemical feed water, saturated steam, condensed water, etc.). Industrial site: 　　 After you have a basic concept, you can Introduce everyone-PH/ORP tester is one of the intelligent online chemical analysis instruments, which is widely used in PH value or ORP in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water. Continuous monitoring of value and temperature. This controller can be used in conjunction with various electrodes. Key parameters and specifications of the acid-base tester: 　　 1. Confirm the use occasion and medium 2. Measure the temperature of the medium 3. Corrosive 4. The specific city of the medium 5. Installation method 6. Corresponding controller output signal and functional application aspects: Generally in medium and large sewage treatment plants, in the 1990s, some foreign imported brands, such as E+H, Mettler, Hash, etc., were mainly used. With the improvement of domestic industrial water products, some domestic manufacturers Also gradually entered this market. For example, Kaidi has done a good job in environmental protection and has one-stop service, which has been recognized by a large number of customers and peers.
level gauge is an inevitable and critical part of being a manufacturer, and it's more complicated than just manufacturing products and serving customers.
Guangdong Kaidi Energy Technology Co., Ltd. has had manufacturing experience for over customized level indicator years. She currently runs a website where they sell . You can visit her site at Kaidi level indicator.
Based on the level gauge, here are the top compliance challenges businesses face, and what you can do to make them easier on ourselves.
