Benchtop Water Quality Meters

Dedicated and Multiparameter Meters

Dedicated meters suit laboratories focused on a specific measurement. Multiparameter meters combine several testing functions in one instrument, providing flexibility when evaluating different aspects of the same sample.

Understanding Water Quality Parameters

pH indicates acidity or alkalinity, while ORP measures oxidation-reduction potential. Conductivity reflects a solution’s ability to carry electrical current. Conductivity-based TDS and salinity readings use conversion relationships to estimate dissolved solids or salt content.

Electrode Selection and Sample Handling

Choose electrodes suited to the sample composition, temperature and measurement range. A probe holder helps maintain consistent positioning during testing. Rinse electrodes between samples and follow the manufacturer’s cleaning and storage instructions to minimize contamination and maintain performance.

Calibration and Temperature Compensation

Use appropriate pH buffers or conductivity standards and follow the meter’s calibration procedure. Temperature affects both sensor response and sample properties, so consider temperature measurement and compensation capabilities when comparing instruments.

Recording Results

For workflows requiring documentation, compare data memory, computer connectivity and software support. The 860033 Benchtop Water Quality Meter includes memory for 99 data points, a computer cable and software.
