High pH Measurement Performance
With Reliability and Precision
Reproducibility and precision are a key priority in the lab. METTLER TOLEDO offers benchtop pH meter measuring technologies that ensure optimal measurement performance for a range of applications.
To ensure reliable measurement results METTLER TOLEDO offers certified calibration solutions for pH, conductivity and ion concentration.
Intuitive Operation pH Meter
OneClick™ User Interface
Productivity is maximized with METTLER TOLEDO's integrated intuitive OneClick™ operation technology.
With a single click you can start a method: a sequence of analysis steps with fixed preset parameters. Using methods makes sure that your particular analysis is always per formed with identical settings.
Compliance and Data Security
Method Creation and LabX® Software
Security functions help support your workflow during calibration, data collection and data archiving. Built-in method creation ensures that analyses are performed with identical settings and parameters. LabX® PC software adds more functionality such as data and resource management. It even allows your benchtop pH meter to connect to other laboratory instruments. Ensure compliance with our benchtop pH meter solutions, even under stringent GLP conditions.
pH Measurement Automation
Efficient Workflow Support
Increase efficiency and measurement repeatability by connecting your benchtop pH meter with the InMotion™ autosampler. Build the autosampler according to your needs with modular boards and additional systems specific to your sample. Support up to 300 samples and automated calibration of sensors while increasing productivity in your lab.
Modular pH Meter
Flexible Parameter Expansion
We offer a benchtop meter that is available as an individually configured single-, dual- and triple-channel meter.
A modular design allows for expansion as well as measurement configuration in any order. The SevenExcellence™ fits up to three measurement modules in any composition and order. It allows for measurements of 1, 2 or 3 parameters simultaneously, either in the same or different samples.

FAQ
Should I have a dedicated or a multi-parameter instrument?
This depends on your application. Dedicated single channel meters can be used to measure one parameter like pH, ORP, ion concentration, conductivity, or dissolved oxygen). Multi-parameter instruments allow you to measure more than one parameter at the same workplace.
What is the difference between linear and segmented calibration?
 |
Please see the above graphs showing the difference between linear and segmented calibration modes.
After performing a segmented calibration with three buffers, two slope and two offset values are given. When performing a linear 3 point calibration, you get only one slope and one offset value based on the line drawn by linear regression (fitted using the least squares approach) between all 3 calibration points.
The difference between these two methods is that the segmented calibration is considered to be more accurate, because it fits more the real behavior of an electrode than just one line.
When performing a measurement after a segmented calibration, the instrument takes the slope and offset according to the pH value measured. For example, if the measured value is pH 5, the slope/offset values between pH 4.00 & pH 7.00 will be used. If the measured value is pH 9, the slope/offset between pH 7.00 & pH 10 will be used.
When performing a measurement after a linear calibration, in case of measured pH 5 and pH 9, the same slope value is used for calculation.
