Application readiness

Installation, calibration and validation

Validate the product with real samples, final mechanics and the intended electrical environment before production.

01
Use the same probe model on all three channels.
02
Separate simultaneously immersed probes by at least 1 m to reduce interaction.
03
Commission and record each channel using the actual plumbing position and expected water range.
