Electrochemistry Meters and Analysers are designed for accurate measurement of key water quality and electrochemical parameters including pH, conductivity, dissolved oxygen (DO), oxidation-reduction potential (ORP), and turbidity in laboratory, field, and educational environments. This category includes benchtop multi-parameter meters, portable testers, pocket meters, and advanced analytical instruments used in research, teaching, environmental monitoring, and quality control workflows.
These instruments support precise electrochemical analysis by using specialised electrodes and sensors to measure ionic activity, electrical conductivity, and chemical properties of liquids. Benchtop meters are suitable for controlled laboratory testing with higher stability and expanded functionality, while portable and pocket testers enable rapid, on-site measurements for water quality assessment and field applications. Multi-parameter systems allow simultaneous measurement of multiple variables, improving efficiency in routine testing and comparative analysis.
For quality and compliance reference, ISO 10523 is a recognised international standard for determination of pH in water, providing a relevant reference for pH measurement practices. ISO 7888 is also a current standard related to determination of electrical conductivity in water, supporting conductivity testing applications. ISO 5814 is applicable for dissolved oxygen determination using electrochemical probe methods, making it relevant for DO measurement instruments. These standards should be referenced only where supported by the instrument’s specifications, calibration procedures, and supplier documentation.
For LabChoice Australia customers, Electrochemistry Meters and Analysers provide reliable solutions for laboratory analysis, environmental testing, education, and industrial quality control. Their precision, versatility, and ease of use support consistent measurement and data accuracy across a wide range of electrochemical applications.
