What is the digital meter of ph?
The digital potential of hydrogen meter (PH) is an electronic gadget used for accurate measurement and recording of liquid pH values. PH measurement allows you to determine the acidity or alkaline of the substance in a liquid state. The PH meter digital device consists of a glass electrode connected to the end of the probe and connected to an electronic device with a digital display. When the pH is measured by the probe, the pH digital meter shows accurate reading in pH units. The pH digital meter is similar to the Voltmer, except for displaying recorded values in pH units rather than volts. One pH unit is equivalent to approximately 0.06 volts. Alkaline buffer at pH 4 and acid buffer at PH 10 is most commonly used for two -point calibration. In situations requiring increased accuracy, a neutral buffer is used for three -point calibration at ph 7.
The use of a digital pH of the meter is simple. It is important to rinse the probe distilledU or deionized water before and after each use. To record the pH of the fabric level, the probe is carefully inserted into the liquid substance, so that the glass electrode is not damaged. Digital PH meter immediately starts to display the values. When reading is stabilized, the measurement is completed and the probe can be removed and rinsed with distilled water.
It is recommended to store digital pH of the digital pH meter at ph 3. In addition, monthly cleaning of the electrode and probe of hydrochloric acid (HCI) is recommended. PH of the cleaning solution should be close to 1.Additional features and functions can be available on selected digital pH models. Some of these options may include portable, waterproof design and added temperature measurement. Special digital pH meters are also made for fabrics such as beer and food.
digital measurement tools such as pH meter are important for maintaining consistent and accurate records. If digital pH meters are not available, there is AlteRative method of pH measurement. A small strip of paper with colored dye can be used to indicate acid -based acid to indicate acidity and alkaline.
