Water Quality Sensors

Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment. Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations.

Traditionally this has been done using water quality sampling methods, but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most reliable and timely means of ensuring that treatment processes are operating efficiently and that EPR compliance is maintained.

We offer a range of state-of-the-art water quality monitoring sensors sourced from internationally renowned manufacturers. All our water quality sensors have been carefully selected for integration with Hydro-Logic™ data loggers and telemetry systems, ensuring reliable unattended operation at remote sites.
