Sensor applications

InPro 7250 ST
This sensor may be used for most routine applications
like conductivity measurement in industrial wastewater
systems. For applications at higher temperatures and for
use in hazardous areas the sensor InPro 7250 HT is the
preferred alternative.
InPro 7250 HT
The InPro 7250 Series sensor is suitable for the majo-
rity of all electrodeless conductivity applications. Its
compact size enables it to be mounted in a multitude of
methods, including insertion (flange, bushing), and
immersion. Typical applications include salinity and
brine measurements, steel pickling, scrubbing towers,
ion exchange regeneration, plating baths, rinse water,
caustic metal cleaning, and textile measurements in
scouring, mercerizing, and carbonizing baths.
InPro 7250 PFA
This sensor is particularly suited for heavy-duty chemical
applications such as Oleum (highly concentrated sulfu-
ric acid), as well as applications in the pharmaceutical
and biopharmaceutical industry (CIP skids, acid and ba-
se concentration).

tance to most aqueous solutions of acids, bases, and
salts. It is also excellent for organic solvents such as
toluene, ethyl acetate, acetone, gasoline, and carbon
tetrachloride. It is not recommended for sulfuric or
nitric acid solutions above 70 %, nor is it recommen-
ded for Oleum applications.
as PTFE. PFA is resistant against nearly all chemicals
and has a high temperature resistance. The PFA qua-
lity used here does not contain glass fibres (virgin
PFA).
