Product Description This food-grade pH meter is a high-precision pH tester for food, featuring an LCD backlight and ATC automatic temperature compensation. It is suitable for pH measurement of food, fruits, meats, canned goods, brewing products, etc. High-Quality pH Meter: This food-grade pH meter is tested before leaving the factory, and the electrodes are resistant to strong acids and alkalis. The sponge inside the electrode cap contains a small amount of protective fluid. After each use, please clean and dry the probe, and replace the protective cap to maintain probe sensitivity. Replaceable pH Probe: This food-grade pH meter uses a replaceable needle probe for easy maintenance. It is more sensitive than ordinary probes and has a wider testing range. Automatic Calibration pH Meter: It uses a high-sensitivity needle probe with a measurement range of 0-14 pH and a resolution of 0.01 pH. Through a three-point calibration procedure and automatic temperature compensation from 0.1 to 60°C, the pH meter can automatically identify the calibration solution and provide a rapid reading. Maintenance: This food-grade pH meter is calibrated before leaving the factory and can be used directly. The electrode cap contains protective fluid. If it is not used for a long time, the battery needs to be removed and the electrode cap replaced. Calibration is required before use again. Wide range of applications: This food pH meter is suitable for testing the pH value of soft solid samples such as cheese, sushi rice, meat, fruit, dough, bread, skin care products, and solid media, and is also suitable for routine pH value testing of general aqueous solutions.
