Groundwater Monitoring - Water Quality Meters

 

In January 2009 Van Walt Ltd was appointed the exclusive UK and Ireland dealer for the YSI Environmental Monitoring and Water Quality Systems for groundwater applications. YSI is known for their excellent and extensive range of market-leading, rugged water quality meters and environmental monitoring systems. Whether you require a single, dual or multiparameter water quality meter YSI equipment will give you reliable and quality data with the minimum of downtime and low maintenance costs.

Choose from a range of meters, systems and accessories to suit your individual monitoring, sampling, purging, level or temperature needs.

Please note that BS ISO 11271 requires that all Redox measurements are required to be translated as if they were taken with a SHE electrode (Standard Hydrogen Electrode). A conversion table and a more detailed explanation can be found on our 'Redox Conversion Table', Information Sheet.
