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.

YSI Pro Plus

The YSI Professional Plus handheld multiparameter meter provides extreme flexibility for the measurement of a variety of combinations.

The new Quatro cable attached to the Pro Plus allows you to utilise 4-ports to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate.

The Pro Plus instrument meets the demands of true field work. The instrument is rated to IP-67 standards even without the battery cover on. Other tough features include a -year warranty, Mil-spec connectors, rubber over moulded case, and a 2-year cable warranty. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability.
