What it is not the answer for
Read this before asking for a price: one of these conditions is what turns a good meter into a bad installation.
- Pure water below about 20 µS/cm: inductive cells lose resolution at very low conductivity
- Sanitary installations where the bore cannot be cleaned in place
- Media with entrained air or heavy solids that break the inductive loop
Maintenance and service life
Clean the toroid bore monthly in scaling or biological service; scale inside the bore is the usual cause of a drifting reading. Verify against a standard solution once a year. There are no electrodes to replace, which is the point of the design.
Behind the instrument
How it is built and tested
Coil winding, the calibration bench, the plant floor — and an overseas customer's factory audit.
Applications
Where this model is used
Each application names a measuring point and the conditions that decide the selection.
Elsewhere in the range

The same category holds the models that solve the neighbouring problem, and the price difference is usually smaller than the cost of the wrong principle.
