HY9100 Acidity meter standard is a high-precision measuring instrument, the following is a detailed overview of it:

I. Overview of the instrument

HY9100 pH meter standard is a precision instrument for measuring the pH value of solution. It adopts advanced measurement technology and high-precision sensor, which can accurately and quickly measure the pH of solution, and provide reliable measurement data for chemical experiments, environmental monitoring, food science, beverage industry, medicine and biochemical research and other fields.

Two, working principle

HY9100 Acidity meter standard The working principle is based on the potential method. It forms a galvanic cell by dipping a reversible hydrogen ion indicator electrode with an internal reference electrode and an external reference electrode into a solution to be measured at the same time, and generates a battery electromotive force between the internal and external reference electrodes at a certain temperature. This electromotive force is related to the activity of hydrogen ions in the solution, and has little to do with the presence of other ions. The instrument is displayed by measuring the size of the electromotive force and converting it into the pH value of the liquid to be measured.

High precision: The HY9100 acidity meter standard uses high-precision sensors and advanced measurement technology to ensure the accuracy of measurement results.

Good stability: The instrument has good stability and can maintain the accuracy and consistency of the measurement results during long-term use.

Convenient operation: HY9100 acidity meter standard is reasonable in design and easy to operate. Users can easily complete the measurement work by simply following the instructions.

Wide range of application: The instrument is suitable for various types of solution pH measurement, including aqueous solution, non-aqueous solution and so on. At the same time, it can also be used to measure various parameters such as ion concentration and potential difference.

Four, the use of

Calibration: Before using the HY9100 acidity meter standard, it needs to be calibrated. The correction process includes two steps: slope adjustment and positioning adjustment. The slope adjustment is used to adjust the sensitivity of the instrument, and the positioning adjustment is used to adjust the zero drift of the instrument.

Measurement: The calibrated HY9100 pH meter standard can be used to measure the pH value of the solution. Insert the electrode into the solution to be tested and gently shake the beaker to make the solution even. After the reading is stable, the pH value of the solution can be read out.
