We are the exclusive UK and Ireland distributor for YSI Water Quality Systems for groundwater monitoring applications. YSI is a global business committed to sustaining the quality and viability of the world's water resources with accurate and reliable water quality testing equipment. Their meters have proved to be rugged, reliable, accurate and durable. We include a range in our rental fleet – testament to their true fieldwork credentials.
Choose from the Pro Series or the versatile YSI 556.
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.
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 3-year warranty, Mil-spec connectors, rubber over moulded case, a 2-year cable warranty and one year probe warranty. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability.
The YSI Pro 20 and ProODO series are water proof, rugged, reliable single parameter handheld meters available for the determination of Dissolved Oxygen. The Pro 20 features the YSI Professional Series Galvanic or Polarographic DO sensors whilst the Pro ODO has an Optical DO sensor.
They both include:
- 3-year instrument warranty and a 2-year cable and probe warranty (Pro 20 Probe has 1 year warranty)
- Military Spec (MS) connectors
- Rubber overmolded case
- Field tested cables
- Rugged, weighted probe guard
The YSI Pro2030 is a durable and easy to use handheld dissolved oxygen / conductivity meter that automatically compensates for changes in salinity values. Rugged, easy to use and reliable, this meter will also measure specific conductance, total dissolved solids (TDS), barometric pressure and temperature.
It also benefits from:
- MS (Military Spec) cable connector
- Choice of field DO sensors: Polarographic or Galvanic
- Rugged, weighted field cables available in lengths from 1 to 30 metres
- Being completely waterproof to 1 metre submersion
- 3-year instrument; 2-year cable; 1-year Polarographic/6-month Galvanic sensor warranty
- Storing 50 data sets to ensure data integrity.
The YSI 556 Multi-Probe Field Meter combines the versatility of an easy to use and read handheld water quality meter but with all the functionality of a multi-parameter, field-ready system that will simultaneously measure Dissolved Oxygen, Redox, conductivity, pH, temperature, and more.
The WTW pH Data Logger is designed for long term, continuous pH/ORP and conductivity surface and groundwater monitoring. These loggers are particularly appropriate for challenging applications and difficult to access locations. Reliable and durable but simple and easy to use the WTW pH Data Logger delivers stable measurements in the toughest conditions.
With a diameter of just 25mm the WTW pH Data Logger is suitable for boreholes and pipes, recording up to 600,000 data sets. A replaceable 3.6 V lithium battery which incorporates power saving features ensures a long service life and, being manufactured of stainless steel, the logger is robust and accurate even in the harshest conditions.
Operating and configuring the instrument is easy with results displayed as a table or graph. Data can be exported as Excel or CSV files for further analysis and interpretation.
