High-quality pH Meter The food pH meter has been tested at the factory, and the electrode is resistant to strong acid and alkali. The sponge in the electrode cover contains a small amount of protective solution. Wash and dry the probe after each use and replace the cap to maintain probe sensitivity. Replaceable pH Probe The pH meter for food measurement features a replaceable spear probe for easy maintenance, offering improved sensitivity and a wider test range compared to standard probes. Automatic Calibration pH Meter Equipped with a high-sensitivity spear probe, this pH meter provides a full measurement range of 0–14 pH with 0.01 pH resolution. Featuring a 3-point calibration process and automatic temperature compensation from 0.1 to 60°C, the meter automatically recognizes calibration solutions for fast and accurate readings. Maintenance The food pH meter is factory calibrated and ready for immediate use. The electrode cover contains protective solution. If the device is not used for an extended period, remove the batteries and keep the electrode cover in place. Recalibration is recommended before subsequent use. Wide Application This food pH meter is suitable for measuring the pH of soft solid samples such as cheese, sushi rice, meat, fruit, dough, bread, skincare products, and solid media. It is also ideal for routine pH testing of general water solutions.
