WE KNOW DO - Every species on our planet depends on water and oxygen. For aquatic species, adequate dissolved oxygen is of prime importance to their continued survival. Since dissolved oxygen levels are directly related to good water quality, the two are highly interdependent. Many factors can affect DO levels, and an understanding of these levels in order to make informed decisions concerning wastewater treatment operations, hypoxic zones, aquaculture facilities or large-scale ecosystems is essential.
When it comes to dissolved oxygen measurement, Xylem offers more knowledge, more experience and more technology options than any other company. "We Know DO™".

Cutting edge technology from WTW for demanding laboratory applications. Two digital inoLab® multi-parameter instruments for IDS sensors for parallel measuring of one identical or varying parameters. Up to three sensors (inoLab® Multi 9430 IDS) can be connected. A large glass shield protects the graphic display and supports the presentation of the measuring values and recognition of important information. The innovative and antibacterial keypad helps to protect against microbiological contamination. The solid zinc die-casting lower case gives the meters a safe standing and also protection from the environment. As a special feature, both models can be upgraded with an additional module for conventional pH measurement.
Connect digital IDS sensors to the Inolab for the measurement of pH, ORP, conductivity, and DO/BOD.
The brand new acoustic profiler joining the SeaGuard family. It features innovative development of the acoustic profiling capacity and an exceptional ability to collect high quality current information on moving and tilting moorings.
