pH Meter

What is a pH Meter?

A pH meter is a scientific instrument used to measure the hydrogen ion concentration (pH) of a solution. It provides a numeric value on the pH scale, which ranges from 0 to 14, with 7 being neutral, values below 7 indicating acidity, and values above 7 indicating alkalinity.

Types of pH Meters

There are various types of pH meters available, including:

• 1. Portable pH Meters: Compact and battery-operated, these meters are ideal for fieldwork and on-the-go measurements.
• 2. Benchtop pH Meters: These stationary meters are designed for laboratory use, offering advanced features and higher accuracy.
• 3. pH Test Strips: While not traditional pH meters, pH test strips are simple and cost-effective tools that provide a rough estimate of pH levels.
• 4. pH Pen Meters: Pen-shaped pH meters are portable and user-friendly, suitable for both professionals and hobbyists.
