High Precision ph Meter with batteries, buffer powders and hard box

Notice: 1.This meter can test any solution, including strong acids, alkali and viscous samples like shampoo. But it cannot test solids like soil and fabric directly, they need to be mixed with water, beforehand.

2. Moreover, strong acid and alkali will greatly affect the service life of the electrode. This is inevitable even if you buy a much expensive acidity meter. 3.The glass bulb sensor of the electrode is fragile. Do not touch the bulb sensor by hard tools or fingers, and handle with care when cleaning.
