9.3.6 PR-23-AC I-Line fitting
Sanitary Refractometer PR-23-AC-ZC can be mounted using 3-A Sanitary approved 2.5
inch Cherry Burrell I-Line fittings that are made of interlocking flat face ferrules, a flat
gasket and a clamp. This interlocking, metal-to-metal design eliminates over com-
pression by the clamp not allowing the gasket to be extruded into the product contact
side.
Sensor wetted parts material is AISI 316L or Alloy C, gaskets EPDM.

9.3.7 Mounting specifics for EHEDG certified PR-23-AC configuration
Vaisala offers certain PR-23-AC configurations which have been certified to fulfill the
sanitary requirements published by EHEDG (European Hygienic Engineering & De-
sign Group) organization. During this certification the hygienic characteristics of both
the refractometer and the process connection were evaluated against the applicable
requirements.
To ensure EHEDG compliant installation, follow the mounting specifics provided on
the mounting drawing supplied by Vaisala with each PR-23-AC refractometer sensor
ordered with the -EH option.
9.3.8 3A Sanitary Standard compliance
The user should ensure that the refractometer is not a source of contamination to
product due to damaged or worn product contact surfaces. Misuse (e.g. too long prism
wash time or too high wash pressure) or mishandling may result in metal scratches
or roughened surfaces. Such surfaces may not stay clean in processing.
