Product Details
Product Overview
The Philips C3540 (21321A) is a broadband convex array ultrasound transducer developed for general abdominal and obstetric/gynecological imaging applications. Designed for legacy Philips and Hewlett-Packard ultrasound platforms, this probe provides reliable penetration and image quality for routine diagnostic examinations in hospitals, clinics, and imaging centers. It is one of the most recognized convex probes used on the Philips EnVisor and HP Sonos ultrasound platforms.
The C3540 features a convex R40 array design and operates within a frequency range of approximately 2–6 MHz, depending on system configuration. The probe is optimized for abdominal, OB/GYN, and general-purpose imaging applications where a combination of penetration depth and anatomical detail is required.
A key feature of the Philips C3540 is its IPX-7 water ingress protection rating, which enhances durability during routine clinical cleaning and disinfection procedures. The probe incorporates biocompatible patient-contact materials and is designed to meet medical imaging requirements for safe patient use.
The C3540 (21321A) is commonly used for abdominal examinations, liver and kidney imaging, pelvic studies, obstetric assessments, gynecological evaluations, and general ultrasound diagnostics. Its proven reliability has made it a long-standing choice for healthcare facilities operating Philips EnVisor, ImagePoint HX, and HP Sonos systems.
