Probe Unit (P.U.), description
The multi-sensor measurement makes it possible to find the water values. The length of the cables for the
pH and RedOx probes is voluntarily limited to 50 cm to ensure good probe reading precision.
The service life of the probes (according to the conditions of use) is around 18 years for the pH probe, 5 years
for the RedOx probe and a lifetime for the conductivity and temperature probes.
Only Pentair probes are compatible and guarantee proper functioning of the MAESTRO probe unit (see p40).

Tighten/loosen the probe bottles.
Never push or pull on the fitted probe bottles
of the end plug
.
The bypass must be isolated by closing the two valves before changing a probe which is at risk
of flooding.
The probe canisters must be filled
with potassium chloride or, failing
this, running water
The cap of the conductivity probe
may not be used for other probes.
