A digital skin pH meter is a compact, portable device designed to measure the acidity or alkalinity of the skin. With a measurement range of 0 to 14 pH, it provides accurate readings that help users monitor skin health and balance. Its digital display ensures clear, easy-to-read results, while the portable design allows convenient use at home or outdoor use.

Suitable for Skin & Fruit
A pH meter is widely used in many fields beyond basic water quality testing. In the food industry, it checks the acidity of fruits and beverages to ensure safety and flavor consistency. In cosmetics and dermatology, pH meters can be used to test skin surface pH. In laboratories, they support chemical analysis and research. It is also applied in aquaculture, hydroponics, and environmental monitoring.

A1: What is a pH meter?
Q1: A pH meter is an electronic instrument used to measure the acidity or alkalinity of a liquid. The device typically consists of an electrode and a digital display. When the probe is placed in a solution, it detects hydrogen ion activity and converts it into a pH reading。
A2: What is the typical pH range a pH meter can measure?
Q2: A typical pH tester can measure a pH range from 0 to 14, which covers the full scale from highly acidic to highly alkaline solutions. Most standard laboratory and portable pH meters are designed within this range。
A3: What causes unstable pH readings?
Q3: Unstable pH readings are usually caused by electrode problems, temperature changes, or contamination. A dirty or clogged glass electrode slows response and causes drift. Improperly stored electrodes lose sensitivity. Temperature fluctuations affect the electrochemical reaction, so readings vary if temperature compensation is not used. Air bubbles on the electrode surface can interfere with measurement.
Tips: Can this digital skin pH meter measure pH on wet and dry skin?
This digital skin pH meter is designed specifically for measuring the pH of skin in a wet condition. It cannot provide accurate readings on dry skin, so the skin must be moistened before use, typically with water or a gentle skin solution. Once the skin is damp, the meter can quickly and reliably assess its pH level, helping monitor skin health, hydration, and the effects of skincare products.
