COLO.SCIENCE – DO / WATER QUALITY INSTRUMENTS
On this page you can choose the right Dissolved Oxygen Meter for laboratory analysis, wastewater control, aquaculture systems and environmental monitoring of surface and ground waters.
COLO.Science combines portable and benchtop DO meters with electrochemical or optical probes, automatic temperature and salinity compensation, multi-point calibration and data logging for compliant reporting and routine quality control.
GROUPS OF DO METERS
- Portable DO meters –
handheld, IP-rated instruments for field sampling, on-site checks of aeration and oxygenation systems, fish farms and surface waters, with fast-response probes and robust housings. - Benchtop DO meters –
high-stability laboratory instruments for precise dissolved oxygen measurement in QA/QC labs, process control and research, with extended calibration options, data management and GLP-compliant documentation.
FEATURED COLO.SCIENCE LAB SOLUTION
COLO.Science supplies complete solutions around each Dissolved Oxygen Meter model: DO probes (electrochemical and optical), temperature and salinity sensors, calibration standards, flow cells and accessories — together with instrument selection, installation, user training and calibration via the LabServis network.
