Flow-through
Installation in by-pass: the water to be measured flows through the probe holder. Suitable for all probes, including amperometric cells, except the tracer probe (in-line, with a T-fitting).
Probe accessories
Probe holders
They bring the water to be measured into contact with the electrodes. Depending on the probe and the system, the electrode is installed in by-pass, in-line or by immersion.
- Flow-through, in by-pass
- In-line, on the pipe
- Immersion, in the tank

Available versions
NPEDIn SAN, up to 40 °C.
PEFIn PMMA, up to 50 °C.
For turbidityFlow-through, for the turbidity probe.
NPED INDFlow-through, for the inductive conductivity probe.
NFIL filterOn the sample water, upstream of the probe holder: it retains impurities that would foul the probes. Two sizes, NFIL 5 and NFIL 10.
In-line
Mounted directly on the pipe, in PVDF, PP, PVC or PVC-C; up to 90 °C (depending on the model) and 7 bar.
Immersion
For installing the probe directly in the basin or tank; in PP or PVC (depending on the model), up to 80 °C.
Available versions
PECAPImmersion probe holder.
Manifold with bleed-off valve
Water sampling, chemical dosing and bleed-off via a motorised valve, for the WT pumps used on cooling towers.

NPED
Water is taken from the pipe, flows through the probe holder and returns to the pipe.
PEF
Similar layout, with the PEF probe holder.
