Philips S4 (21330A) Phased Array Ultrasound Probe

When your department needs to source a replacement S4 (21330A) phased array transducer for an HP ImagePoint or Philips EnVisor console, the listing below sets out what you can expect from the catalogue record. This item is offered as a new aftermarket-compatible unit, meaning it is built to interface with the named systems, not manufactured by Philips. For procurements that involve the original Philips S4 (21330A) transducer, a separate repair service is listed as a condition option on this page.

Condition grading drives every purchasing decision here. New aftermarket-compatible units arrive without prior clinical use, while the repair service applies to your existing probe. Inspection scope, test coverage, delivery timing and commercial terms are agreed individually per order, after you contact us with your system serial and intended application. No universal assurances appear in this catalogue because each unit and each receiving site has its own requirements.

For sourcing decisions across this catalogue, compare the Phased Array Probes category alongside the Philips S3-1 Phased Array Ultrasound Probe and this S4 record to match your console.
