The Masimo 2651 Adult Soft Tip SpO2 Sensor is a new, reusable silicone finger sensor with a 1.0m cable, built to the Masimo 2651 (DBI-dc3) reference specification for monitors that use Masimo SET pulse oximetry technology. It measures oxygen saturation (SpO2) and pulse rate on adult patients and is supplied with a 12-month warranty.
Key Benefits of This Adult Soft Tip Pulse Oximeter Sensor
- Comfortable for longer monitoring: The flexible soft tip boot spreads pressure evenly around the finger, which suits extended spot checks and continuous monitoring.
- Reusable design: Made to be cleaned and used again between patients, lowering the cost per use against single-patient adhesive sensors.
- Short 1.0m lead: A tidy cable length for bedside, transport and handheld oximeter use where a long lead gets in the way.
- Masimo SET technology: Made for equipment that runs Masimo SET signal processing.
- Supplied new: Covered by a 12-month warranty.

Works With
This sensor is made for pulse oximeters and patient monitors that accept the Masimo 2651 (DBI-dc3) sensor and use Masimo SET technology. Before ordering, match the reference number on your current sensor and check the connector on your monitor or patient cable. If you are unsure, send us your monitor make and model and we will confirm the fit.
Use Cases
- Continuous SpO2 and pulse rate monitoring on adult patients in wards and recovery
- Spot-check oximetry in clinics, day surgery and outpatient settings
- Bedside and transport monitoring where a short cable is preferred
- Biomedical engineering spares for Masimo SET equipped devices
Application and Care
- Place the sensor on a clean, dry finger with the fingertip fully inserted to the end of the soft tip.
- Route the cable along the back of the hand so it does not pull on the sensor.
- Check the site regularly and move the sensor to another finger during long monitoring sessions.
- Clean and disinfect between patients following your facility protocol. Do not autoclave or immerse the connector.
- Inspect the cable and boot for damage before each use.
