Originally designed as a companion product to protect the InPro 3300 ISFET
pH electrode from caustic CIP conditions, the unique benefits of the InTrac 798e
housing can also be used with all 120 mm sensors. The InTrac 798e is
completely self-contained and has none of the external moving parts commonly
associated with retractable housings. Regardless of the insertion depth selected,
less costly 120 mm sensors are needed to operate the InTrac 798e, which
reduces overall operating expenses and inventory requirements.
Absolute cleanability is possible because the flushing chamber drain and O-ring
have been optimally positioned to assure all CIP solutions are completely drained
from the chamber prior to the sensor being re-inserted into your process.
