9.3.6 PR-23-AC I-Line fitting
K-Patents 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 compression by the clamp not allowing the gasket to be extruded into the product
contact side.
Sensor wetted parts material is AISI 316L or Hastelloy C, gaskets EPDM.

9.3.7 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.
K-Patents offers a 3A Sanitary Standard Accepted repair and maintenance package in
which all wetted parts, prism, gaskets and dryer are replaced. Note that this repair
service can be completed only by a 3A authorized service center (K-Patents factory or
regional headquarters).
