Use Water Detective 4 for any new deployment.
Treat this page as lifecycle and installed-base reference information.
Legacy support should be confirmed before repair or replacement planning.
Use the product as part of a complete measurement workflow, not as an isolated component. Confirm the water matrix, target range and decision that the data must support.
Compact, reagent-free sensing for rivers, lakes, reservoirs and distributed environmental networks.
Track changes in water conditions continuously to support healthier stock and more responsive operations.
Integrated TDS and conductivity components for dispensers, purifiers, filter-life estimation and quality indication.
Define the measurement objective and expected range.
Match the sensor, probe or analyzer to the real sample matrix.
Complete mechanical, electrical and communication integration.
Validate results with reference samples before routine operation.
Validate the complete system with representative samples. Record the reference method, temperature and installation conditions. Recheck after cleaning, replacement or process changes, and define a maintenance interval from actual fouling rather than a fixed assumption.
View current Water Detective 4 →The product platform is defined, but range, calibration and installation must still be confirmed against the actual water matrix and project objective.
Confirm power, interface, cable length, enclosure, sampling frequency, probe position and the host system data format.
Compare representative samples with an agreed reference method and document the acceptance criteria before commissioning.
Yes. Ask for the current ordering specification and describe your application so the correct materials can be supplied.
