Benchtop pH/Conductivity Meter

Updated: 2026-07-21

Overview

The desktop acid-alkali-salt concentration meter is an essential tool for laboratories and industrial settings where precise measurement of solution concentrations is required. It is designed to provide accurate readings of acid, alkali, and salt concentrations, ensuring quality control and process efficiency. This device typically features a digital display, intuitive controls, and advanced sensors to deliver reliable results. It is commonly used in chemical manufacturing, water treatment, and food processing industries, where maintaining specific concentration levels is critical.

Structure and Working Principle

The concentration meter consists of a main unit with a digital display, electrodes for measurement, and a temperature sensor for compensation. The electrodes detect the ionic activity in the solution, which is then converted into a concentration reading. The device operates on the principle of conductivity or potentiometric measurement, depending on the model. Temperature compensation ensures accurate readings by adjusting for variations in solution temperature, which can affect ionic activity.
