①. Food pH Meter, with LCD backlight and ATC. 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 cap contains a small amount of protective solution. Wash and dry the probe after each use, and replace the cap to maintain the sensitivity of the probe. ②. Replaceable pH Probe: The food pH meter has a replaceable spear probe for easy maintenance, which is more sensitive and has a wider testing range than conventional probes. ③. Automatic Calibration pH Meter: With the high - sensitivity spear probe, you can get a full measurement range of 0 - 14 pH and a resolution of 0.01 pH. With a 3 - point calibration procedure and 0.1 - 60 automatic temperature compensation, the pH meter will automatically recognize calibration solutions and quickly display readings. ④. Maintenance: The food pH meter is calibrated at the factory and can be used directly. There is a protective solution in the electrode cover. If it is not used for a long time, the batteries should be removed and the electrode cover should be covered, and it should be calibrated again before use. ⑤. Wide application: This food pH meter is suitable for testing the pH of soft and hard samples such as cheese, sushi rice, meat, fruit, dough, bread, skin care products, solid media, etc., and is also suitable for routine pH testing of general aqueous solutions.
