Description
Cables & Sensors Masimo Compatible Disposable SpO2 Sensor is a disposable spo2 sensor from Cables & Sensors built as a compatible replacement for Masimo equipment. It cross references to original part numbers such as Masimo 1859 LNCS Adtx (18"), so the swap keeps the equipment in service instead of sidelined. For respiratory, nursing and monitoring teams, that means one verified part number for pulse oximetry and oxygen saturation monitoring and no guesswork at reorder time.
- Masimo Compatibility – Built as a compatible replacement for Masimo monitors, with the fit verified against the manufacturer's own compatibility table.
- OEM Cross Reference – Matches original part numbers including Masimo 1859 LNCS Adtx (18"), which makes matching the old part simple.
- Lab Tested Quality – Every product is tested by the manufacturer's lab to meet or exceed ISO and FDA guidelines.
- 4 Configurations – Each configuration keeps its own part number and price on this listing, so the exact item is easy to pick.
Disposable SpO2 Sensor Built for Pulse Oximetry And Oxygen Saturation Monitoring
The disposable spo2 sensor reads functional oxygen saturation and pulse rate at the patient site and feeds the signal to the monitor. The manufacturer's compatibility table covers 30 equipment brands for this line, with Masimo fit confirmed on the product page. This listing carries 4 configurations (Adult (>40Kg) Box of 20, Infant (3-15Kg) Box of 20, Neonate (<3Kg) or Adult (>40Kg) Box of 20, Pediatric (10-50Kg) Box of 20), and each one keeps its own part number and its own formula price. Packaging is stated exactly as the manufacturer and distributor list it: 20/bx. Stocking the matched disposable spo2 sensor ahead of failure keeps a monitor or device earning its place on the floor, and the care team feels that reliability first.
