Benchtop pH meters are analytical instruments used in laboratories and near production to measure the pH value and other parameters such as conductivity, ion concentration, ORP, and dissolved oxygen. They are easy to use and simplify results documentation. Choose from intuitive benchtop meters for routine measurements to advanced systems for automated and compliant measurements.
pH, conductivity or dissolved oxygen are common parameters that are often measured in the laboratory. Choose from single- or multi-channel benchtop meters to measure up to three parameters simultaneously in the same or different samples.

Benchtop pH meters are devices for pH measurement that are designed to be placed and used on a laboratory bench or similar work surface.
First of all, the instrument should measure the required parameter (e.g. pH, conductivity, dissolved oxygen concentration) with the desired accuracy. Secondly, review which ease-of-use features and data handling options are useful for you. Finally, no meter is complete without a sensor. A ready-to-use kit comprising meter, sensor and calibration solutions is the perfect way to get started.
That depends on what the data is used for and how long it has to be stored. Manual note keeping, e.g. in a paper-based or electronic lab notebook carries a high risk of transcription errors. The internal device memory of your benchtop pH meter is great for short term storage, but may not meet organizational or legal archiving requirements. For long term, safe results documentation, automatic printouts or transfer of measurement results to a software (to be used together with your benchtop meter) such as LabX™ provide convenience and safety.
Methods on a SevenDirect™ benchtop meter combine all the parameters for measurement, calibration and verification. There is no need to adjust each parameter individually, simply save the correct combinations for common samples and switch with just two clicks. Workflow methods on a SevenExcellence™ benchtop meter go a bit further, providing options such as specific guidance, multi-step procedures and customizable results calculation. Program SOPs into workflow methods to simplify work and avoid errors.
