RS Hydro supply, hire, calibrate and maintain a wide range of water quality monitoring equipment. Whether you need to measure one parameter or many, we can provide the perfect solution for your application.
The most versatile, accurate and user-friendly probe on the market, the Troll 9500 has set a new standard for multi-parameter water quality monitoring. With the ability to measure dissolved oxygen, conductivity, turbidity, pH, level/depth/pressure, ammonium, chloride, nitrate and temperature, it provides a complete solution to most water quality monitoring applications.
The Troll 9500 has a corrosion resistant housing suitable for fresh, waste and marine waters, field replaceable sensors for easy calibration and maintenance.
The latest water quality instrument from In-Situ® Inc., The Aqua Troll 200 is built for extended deployment with a design that combats fouling and conserves power. This device can monitor and log conductivity, level/pressure and temperature in the most demanding environments.
The design builds on the industry leading Level TROLL platform. With an ultra-rugged, corrosion-resistant titanium construction and a small 0.72" (18.3mm) diameter, the Aqua TROLL 200 is ideal for demaning marine, surface and groundwater applications. It runs on external 8-36 VDC or internal batteries that are guaranteed for 5 years when reading every 15 minutes.
The Aqua TROLL 200 is also one of the easiest water quality monitoring devices to use, with twist-lock cable connectors and industry leading Win-Situ software. It can be used in the field with the durable RuggedReader handheld PC, which can provide fast instrument set-up and downloading.
Water Quality Monitoring is defined by the ISO as "The programmed process of sampling, measurement and subsequent recording or signalling, or both, of various water characteristics, often with the aim of assessing conformity to specified objectives". These processes will usually fall into one or more of the following four categories:
