Applications
Typical applications
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.
Surface Water Monitoring
Compact, reagent-free sensing for rivers, lakes, reservoirs and distributed environmental networks.
Aquaculture
Track changes in water conditions continuously to support healthier stock and more responsive operations.
Drinking Water & Purification
Integrated TDS and conductivity components for dispensers, purifiers, filter-life estimation and quality indication.
Technology
From selection to reliable data
- 01
Define the measurement objective and expected range.
- 02
Match the sensor, probe or analyzer to the real sample matrix.
- 03
Complete mechanical, electrical and communication integration.
- 04
Validate results with reference samples before routine operation.
Engineered for dependable integration
Integration and installation checklist
- ✓Target parameters and expected concentration range
- ✓Water matrix, fouling risk and installation method
- ✓Communication interface and sampling frequency
- ✓Calibration, validation and maintenance strategy
- ✓Information to provide for selection: Water Detective 3 · Portable Water Analyzers
Calibration, validation and maintenance
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.

Frequently asked questions
Is this product ready to use in every water matrix?
The product platform is defined, but range, calibration and installation must still be confirmed against the actual water matrix and project objective.
What should be checked before integration?
Confirm power, interface, cable length, enclosure, sampling frequency, probe position and the host system data format.
How should measurement quality be verified?
Compare representative samples with an agreed reference method and document the acceptance criteria before commissioning.
Can datasheets, protocol information and engineering support be supplied?
Yes. Ask for the current ordering specification and describe your application so the correct materials can be supplied.
