Masimo 4055 RD SET TF-I All Sizes Forehead SpO2 Sensor 1.0m (Reusable New)

The Masimo 4055 RD SET TF-I forehead SpO2 sensor is a new, reusable pulse oximetry sensor with a 1.0m cable, built to the Masimo 4055 (RD SET TF-I) and Draeger MS40073 reference specifications. It is applied to the patient’s forehead instead of a finger, plugs into Masimo RD SET patient cables and monitor ports, and is specified for all patient sizes.

Key Benefits of This RD SET Forehead Pulse Oximetry Sensor

• Reusable design: Cleaned between patients and used again, lowering cost per use compared with single-patient adhesive sensors.
• Masimo RD SET connection: Flat RD style plug for Masimo RD SET patient cables and RD equipped monitors.
• 12-month warranty: Supplied new and covered for 12 months.
