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.
