With the rapid development of modern technology, portable pH testing systems have been widely used in many fields due to their high efficiency, convenience and accuracy. Especially in the textile industry, the emergence of the Ningbo Textile Instrument Factory portable pH testing system has greatly improved the accuracy and efficiency of monitoring the pH of textile water extracts, which is of great significance for ensuring product quality and safeguarding consumer rights.
Basic principles of portable pH testing system
The portable pH testing system is based on the principle of electrochemistry and measures the concentration of hydrogen ions (H+) in a solution to determine its pH. The system usually includes electrodes, circuits, and displays. The electrode is responsible for sensing the ionic activity in the solution, and the circuit converts the sensed signal into a readable pH value and presents it through the display. Due to its compact design and simple operation, the portable pH testing system is ideal for fast and accurate pH measurements in the field.
Application of portable pH testing system in monitoring the pH of textile water extracts
Preparation of aqueous extracts of textiles
In the preparation process of textile water extracts, textiles need to be mixed with water according to a certain ratio and method, and an aqueous solution containing chemical substances that may be released from textiles is obtained through extraction. This step is the basis for subsequent pH monitoring and is crucial to ensuring the accuracy of test results.
Application steps of portable pH testing system
(1) Calibration: Before using the portable pH testing system, it first needs to be calibrated to ensure the accuracy of the measurement results. During the calibration process, the electrode needs to be calibrated using a standard buffer solution to eliminate errors.
(2) Measurement: Immerse the calibrated portable pH testing system into the textile water extract and wait for a moment to allow the electrode to fully sense the ionic activity in the solution. Then, read the pH value on the display to get the pH of the water extract.
(3) Recording and analysis: Record the measured pH value and conduct comprehensive analysis in conjunction with other relevant data. By comparing the pH of water extracts from different textiles, the potential impact on human skin can be evaluated, providing a basis for product quality control and improvement.
Precautions
When using a portable pH testing system to monitor the pH of textile water extracts, you need to pay attention to the following points:
(1) Ensure the electrode is clean and dry to avoid contamination and errors.
(2) During the measurement process, the electrode must be kept in full contact with the solution to obtain accurate measurement results.
(3) For different types of textiles, different extraction methods and conditions may be needed to obtain representative water extracts.
(4) Regularly maintain and maintain the portable pH testing system to ensure its long-term stable operation and accurate measurement.
