A pH meter is an instrument used to measure the pH of a solution. The pH meter works on the principle of a primary battery. The electromotive force between the two electrodes of the primary battery is based on Nernst's law, which is not only related to the properties of the electrodes, but also to the concentration of hydrogen ions in the solution. There is a corresponding relationship between the electromotive force of the primary cell and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value. pH meter is a common analytical instrument widely used in agriculture, environmental protection and industry. Soil pH is one of the most important basic properties of soil. Factors such as temperature and ionic strength of the solution to be measured should be considered in the pH measurement process.   ² Color High contrast LCD touchscreen, 7.0 inches. ² Intelligent operation system provides features including user management, calibration management, method management, data management and etc. ² Multi-reading feature allows auto-read, timed-read and continuous-read. ² Automatic/Manual temperature compensation ensures accurate results. ² Data Storage 1000 sets for each parameter (GLP-compliant). ² Data analysis feature helps user review, compare and recalculate results. ² Support for USB or RS-232 communication. ² Reset feature automatically resumes all settings back to factory default options. ² IP54 waterproof. ² 1-6 points calibration with Standard Recognition. ² Selectable pH buffer groups, including NIST, DIN, GB. ² Support for pH standard group customization. ² Automatic electrode diagnosis with pH slope and offset display.   PRODUCT SPECIFICATIONS :
