In the world of oxygen monitoring, Masimo has built a reputation for precision and reliability. From widely Masimo SpO2 sensors used models such as Masimo 1863, Masimo 4053 and Masimo 4050, to advanced Rainbow SET and Masimo ear sensor solutions, each product is designed to deliver accurate oxygen saturation readings across a wide range of clinical conditions.
Masimo products combine advanced signal processing, durable design, and seamless system integration to support dependable SpO2 monitoring where accuracy is non-negotiable.
The science behind Masimo SpO2 sensors
At the core of Masimo’s monitoring systems is its SpO2 sensor technology. These sensors are engineered to measure blood oxygen saturation using advanced signal processing that minimizes motion artifacts and improves performance in low-perfusion situations.
Key capabilities include:
Accurate SpO2 readings even in motion-prone environments
Reliable performance during low perfusion or complex monitoring conditions
Seamless integration with Masimo oximeters and SET Pulse Oximetry systems
This technology is designed to reduce uncertainty and increase confidence in every measurement, supporting clinical decision-making and long-term monitoring reliability.
Masimo sensor options: Adaptability meets precision
Masimo offers a broad range of sensor options to accommodate different patient types, care settings, and workflow requirements:
Disposable SpO₂ Sensors: Single-use solutions designed for convenience and infection control, without sacrificing measurement accuracy like the LNCS Adtx series (1859, 1860) or Rainbow R20/R25 series, providing convenience without compromising accuracy.
Direct-Connect Sensors: Sensors engineered for immediate compatibility with Masimo monitoring systems, enabling fast setup and stable performance.
Rainbow SET Sensors: Advanced multi-parameter sensors capable of monitoring oxygen saturation alongside additional physiological metrics in real time.
Combined with adapter cables such as 2364, 2055, 2405, and others, the sensors maintain perfect connectivity, ensuring every reading is accurate and uninterrupted.
Expanding functionality with accessories
Beyond the sensors themselves, Masimo offers accessories that enhance measurement reliability:
These components allow every monitoring system to operate at its full potential, supporting consistent and precise data flow across devices.
Connecting technology and reliability
Whether using Masimo SpO2 sensors, Masimo oximeters sensors, or SET Pulse Oximetry systems, reliable oxygen saturation monitoring depends on the quality and compatibility of every component in the system.
