most aqueous solutions of acids, bases, and salts. It is also
excellent for organic solvents such as toluene, ethyl aceta-
te, acetone, gasoline, and carbon tetrachloride. It is not
recommended for sulfuric or nitric acid solutions above
70 %, nor is it recommended for Oleum applications.
Application
This sensor is suitable for the majority of all electrode-
less conductivity applications. Its compact size enables
it to be mounted in a multitude of methods, including ins-
ertion (flange, bushing), and immersion. Typical appli-
cations 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 car-
bonizing baths.
This sensor is identical in physical size and appearance
to the InPro 7200 sensor and may be applied to any of
the applications identified which have intermittent or con-
tinuously high temperatures. Additional high temperatu-
re applications for which this sensor is suited include
alumina-to-caustic ratio, boiler blowdown, and Clean-
ing-In-Place (CIP) measurements in food and related
industries.
This general purpose, sensor may be used for most rou-
tine applications involving low (<20 %) concentrations
of inorganic acids (hydrochloric, nitric, sulfuric, etc.),
bases (caustic, calcium hydroxide, etc.), and salts
(sodium chloride, calcium chloride, sodium sulfate,
etc.). When doubtful about the effect of high levels of che-
micals, temperatures, or abrasion, the InPro 7200 PEEK
sensor is a preferred alternative.
