Water Quality Data Loggers
Continuous telemetry data loggers for water quality compliance monitoring, early contamination warning and automated regulatory reporting.
Manual sampling misses contamination events that occur between sampling rounds.
A weekly grab sample generates 1 data point; a 15-minute interval data logger generates 672 per week, detecting contamination events, treatment upsets and diurnal variation that manual sampling misses entirely. Jos•Hansen supplies In-Situ AquaTROLL and Xylem YSI EXO data logging systems for fixed station water quality monitoring, providing continuous telemetry, cloud data management and automated regulatory reporting. All data is time-stamped and archived with calibration metadata, creating a tamper-evident record for national environment agency submission.
672x more data
A 15-minute interval data logger generates 672 data points per week versus 1 grab sample, detecting short-duration contamination events, daily variation and treatment upsets that weekly manual sampling misses entirely.
Cloud dashboards
Xylem DataHub and In-Situ HydroVu cloud platforms aggregate data from multiple monitoring stations, generate automated compliance reports and provide real-time dashboard access from any web browser or mobile device.
Tamper-evident records
Continuous time-stamped data archives with calibration records and QA flags generate regulatory-compliant documentation for national environment agency submission without manual transcription.
Continuous logging detects contamination events manual sampling misses.
Data archives include parameter values, calibration coefficients, sensor serial numbers, QA flags and GPS station coordinates, creating a complete audit-ready record satisfying national environment agency data quality requirements. Export formats include CSV, XML and direct API transfer to national environmental data repositories. Jos•Hansen provides data management system setup, user training and ongoing technical support for all installed logging networks.
Cloud platforms enable multi-site network management.
Xylem DataHub and In-Situ HydroVu cloud data management platforms receive telemetry from multiple monitoring stations, aggregating data in a single dashboard with map-based station status views. Automated compliance reports are generated in national environment agency required formats, eliminating manual data compilation. Role-based access allows regulators, utility managers and field technicians to access data appropriate to their function without sharing full system access.
Regulatory-compliant archives satisfy audit and enforcement requirements.

Why Water.
Regulatory-compliant records
Tamper-evident data archives with calibration metadata satisfy national environment agency data quality requirements for compliance submissions and enforcement actions.
Automated regulatory reporting
Cloud platforms generate compliance reports automatically, eliminating manual data compilation and reducing compliance management burden on utility staff.
Network-scale management
Multi-site cloud dashboards give utility managers and regulators real-time status of all monitoring stations across a service area from a single interface.
Early warning capability
Threshold alarms notify operators within minutes of a contamination event, enabling intervention before affected water reaches consumers in the distribution network.
