pH and Conductivity Meters
Solutions for pH and Conductivity in Single and Multi-Channel Configurations
A pH and conductivity meter is an analytical instrument that measures both pH and conductivity. pH indicates a solution's acidity or alkalinity, and conductivity indicates its ability to conduct electricity, which is related to the solution's ion concentration. METTLER TOLEDO’s digital meters are used in applications such as water quality testing, chemical analysis, and agricultural testing. They provide highly accurate, precise, and dependable data.

FAQs
Can a pH meter measure conductivity?
Generally, a pH meter cannot measure conductivity. A pH meter measures the acidity or basicity of a solution, while a conductivity meter measures a solution's ability to conduct an electrical current. The two parameters are related such that the conductivity of a solution can affect its pH value, but they are not interchangeable.
If you need to measure both pH and conductivity, consider purchasing a dual- or multi-channel meter that can measure both pH and conductivity.
METTLER TOLEDO manufactures both dual- and multi-channel meters capable of measuring pH, conductivity, and dissolved oxygen. They are designed for applications where numerous measurements need to be taken simultaneously. Explore our range of pH and conductivity meters for laboratory and field use.
How does a pH and conductivity meter work?
A pH and conductivity meter is a type of dual-channel meter that works with two separate sensors for each parameter. METTLER TOLEDO offers a variety of easy-to-use pH and conductivity meters that deliver fast and efficient results. With our meters, you can export data, print results, and connect to software to enhance compliance and help improve the efficiency and accuracy of your laboratory work.
What are the units for pH and conductivity?
The units for pH and conductivity are different.
pH is measured in pH units or pH and is defined as the negative logarithm of the hydrogen ion concentration. It indicates the acidity or basicity of a solution on a scale of 0 to 14. A solution with a pH of 7 is neutral, a pH less than 7 indicates acidity, and a pH greater than 7 indicates basicity.
The conductivity measurement unit is typically Siemens per meter (S/m) or microsiemens per centimeter (μS/cm). It measures the ability of a solution to conduct electricity, which is related to the concentration of ions in the solution.
What are the types of pH conductivity meters, and which one is best for my needs?
There are many types of dual-channel pH conductivity meters available, and choosing the best one for your needs will depend on various factors, such as the application, the accuracy and precision required, and the budget available. Here are some of the most common types of pH conductivity meters:
- Portable pH conductivity meters
- Benchtop pH conductivity meters
- In-line pH conductivity meters
- Combination pH conductivity meters
