AQ² is ANB's next generation, calibration-free pH sensor - built for reliability and long term performance.
Powered by ANB's patented solid-state technology, AQ² removes the need for manual calibration and the fragility of glass electrodes. It self-calibrates in-situ for consistent accuracy, saving time and maintenance costs.
Designed for use in freshwater to seawater environments, AQ² works across a range of deployments such as environmental monitoring, aquaculture and drinking water treatment. The sensor is ruggedized for real world applications and can be stored wet or dry with no loss of performance.
Patented in-situ auto-calibration — no buffers, no operator intervention
Operates across 0.1-40 ppt salinity; wet or dry storage with no degradation
5m, 50m, 300m and 1250m for any deployment scenario
Long-duration open-water deployments for baseline and trend data.
Reliable near-shore pH tracking through dynamic conditions.
Continuous pH intelligence for transitional and inland waters.
Stable pH monitoring for farm productivity and fish welfare.
Rugged sensing for remote offshore programmes.
High-volume datasets for scientific studies and reporting.
Practical long-term monitoring for local and regional water quality.
