This PH meter has a  large black LCD display with a soft backlight can easily cope with various environments, displaying both PH value and temperature value (celsius and Fahrenheit adjustable). PH measurements, with measuring ranges of 0.00 - 14.00 pH, with a PH calibration function. With the automatic temperature compensation function, the compensation ranges from 0.1-60.0 degrees C. Wide applications, suitable for food processing, like fruit, meat, brewing food, canning food, food fermentation, brewing water, cheese, dough, soil, cosmetics, and other solid and semi-fixed sample PH value testing. Features: A large black LCD display with a soft backlight can easily cope with various environments, displaying both PH value and temperature value (celsius and Fahrenheit adjustable). PH measurements, with measuring ranges of 0.00 - 14.00 pH, with a PH calibration function, with calibration ranges of 6.86 / 4.00 / 9.18 or 7.00 / 4.00 / 10.01. With the automatic temperature compensation function, the compensation ranges from 0.1-60.0 degrees C. The PH values of soft solids such as soil, cheese, meat, etc. are measured quickly and accurately by using puncture-type electrodes. The electrodes are replaceable and more convenient for maintenance, with an electrode cover and electrode protections fluid inside. Support for version 5.2 BT via cellphone APP, which supports product parameters view, view stored calibration records. Data synchronization display, where PH meter data will be synchronized to APP can display multiple data at the same time, long-term recorded data, for easy comparison and analysis. You can set your own maximum or minimum measurement, which will be shown in red if the test results are out of ranges. With the data-hold feature, data can be saved automatically and manually, and notes can be added to show location in manual save mode. Data can be exported to Excel for viewing and sharing with friends, supporting views of measurements, times, dates, notes, locations, etc.​ Wide applications, suitable for food processing, like fruit, meat, brewing food, canning food, food fermentation, brewing water, cheese, dough, soil, cosmetics, and other solid and semi-fixed sample PH value testing.
