3.2 Compliance
i Probes are factory tested and are delivered with a certificate of compliance with
specifications.
Models 8398.2 and 8398.3 are particularly well-suited to applications where
sanitary requirements are extremely stringent (compliance with the European food
directive 90/128/CE modified by directive 93/9/CE). Indeed, these probes do not
possess any retention zones that could allow the development of bacteria
(interstices, slits, joints, etc.) and have a roughness inferior to 0.5 μm (optional
certificate, ref. 08398=T=1111).
i The measurement chain, made up of an 8398 probe and of our conductivity
transmitters, complies with European directives 89/336/CEE and 73/23/CEE
modified by directive 93/68/CEE.
