HP Sonos 4500

This page covers the probes catalogued for the HP Sonos 4500 — 27 references in total, each carrying its own failure-mode table and quoting requirements. Philips and HP account for most of what is catalogued on this system. The mix runs to linear, TEE and pencil CW, and failure patterns follow the design — lens membrane wear and strain-relief fatigue shows up most on this kind of head. The exact system build matters, so include the console model with the probe label when asking for a quote.
