Masimo 2508 M-LNCS Adtx Adult Adhesive SpO2 Sensor, 18 in, 20/Box
Works With:
| Patient Cable | rainbow RC cable, no adapter: 2405 RC-1, 1 ft, 2406 RC-4, 4 ft, 4481 RC-4 EMS, 4 ft.34 M-LNC cable (Masimo SET devices): 2523 M-LNC-1, 1 ft, 2524 M-LNC-4, 4 ft, 2525 M-LNC-10, 10 ft.5 |
|---|---|
| Monitor Connector | Philips Tempus Pro (25-pin right-angle rainbow port): the 20-pin RC cables above do not fit that port. Philips Annex B lists the rainbow RC4 RA cable (01-2088, 12NC 989803182411, Masimo 3375; ask us for the 3375), which takes M-LNCS sensors; the 25-pin right-angle 4485 RC25-4RA EMS, 4 ft is the RC25 cable we list.31011 |
| Not For | The 12 ft RC-12 (2404), which Masimo marks No for 18 in sensors, and LNC and Red LNC cables.35 |
| Monitors |
LIFEPAK 15: Stryker's 2019 guide lists the adult M-LNCS adhesive sensor (11171-000039) on RC cables; the 02/2025 guide lists none, so a Red LNC bag takes the LNCS Adtx (1859).712 Zoll X Series and Propaq: Zoll's item field reads "Propaq, X Series, X Series Advanced".9 Masimo Rad-57: listed on rainbow cables.13 Philips Tempus Pro: Annex B lists only the 3 ft Adtx-3 (2509).10 |
| Not Listed For | LIFEPAK 20e and LIFEPAK 35: neither Stryker guide lists an M-LNCS sensor. Use the LNCS Adtx (1859, Stryker 11171-000019).1415 |
| Stryker / Physio-Control Number | 11171-000039. Stryker's 2019 guide lists one adult M-LNCS adhesive sensor under it, with no lead length; the cross-reference assigns it to the 18 in Adtx.78 |
| Zoll Number | 8000-000475, Zoll's M-LNCS Adtx, Adult Adhesive Sensor, 20 per box. Zoll prints no Masimo number, so the match rests on the name and the box.9 |
| Cross-Reference | See the Masimo 2508 row in the Masimo Part Number Cross-Reference |
Product Highlights:
- No adapter: The M-LNCS connector locks into a rainbow RC or M-LNC cable, and the same RC cable takes rainbow sensors when SpCO or SpMet is needed.13
- 18 in lead: The shorter adult lead adds 1.5 ft to the cable, so a 4 ft RC-4 reaches about 5.5 ft from the monitor; the 3 ft Adtx-3 reaches about 7 ft.23
- Site: The middle or ring finger of the non-dominant hand, or a toe; check it at least every 8 hours.1
- Accuracy: On Masimo SET, SpO2 is within 2% Arms with no motion and at low perfusion and 3% with motion; pulse rate is within 3 bpm, or 5 bpm with motion.1

Who Uses This:
- Fire Departments: Fire crews run it on an adult's finger through a rainbow RC cable for rehab and on-scene SpO2 and pulse rate checks.13
- EMS Agencies: Ambulance crews run it on an adult's finger through an RC cable and reorder by Zoll 8000-000475 or Stryker 11171-000039.89
- Flight and Critical Care Transport: Flight and critical care crews keep an adult's SpO2 and pulse rate reading through patient motion, since the sensor is labeled for motion and low-perfusion conditions in mobile environments.1
- Clinics and Urgent Care: Clinic and urgent care staff use it for adult spot checks and short monitoring on a Masimo SET monitor with an M-LNC or rainbow RC cable.15

Frequently Asked Questions:
Which patient cable does the Masimo 2508 plug into, and is there an RD SET adapter?
A rainbow RC cable (2405, 2406 or 4481) or an M-LNC cable, with no adapter.345 It does not fit RD SET, RD rainbow SET, LNC or Red LNC cables, and the 12 ft RC-12 (2404) is marked not for 18 in sensors.35 RC cables need a rainbow SET device, version 7.1 or higher.3
Does the Masimo 2508 work on a LIFEPAK 15, and what are Stryker 11171-000039 and Zoll 8000-000475?
On a LIFEPAK 15 it runs on an RC cable, the route Stryker's 2019 guide lists for 11171-000039; the 02/2025 guide lists none.712 Zoll's M-LNCS Adtx, 8000-000475, matches by name and box and is listed for "Propaq, X Series, X Series Advanced".9
Masimo 2508 Adtx or 2509 Adtx-3: which should I order?
Order the one your reorder sheet matches. The 2508 has an 18 in lead and carries the Stryker and Zoll numbers in the cross-reference; the 2509 has a 3 ft lead, which Philips lists for the Tempus Pro (01-2090).2810 Both are for patients over 30 kg and ship 20 per box.1
Will the Masimo 2508 work on a LIFEPAK 35 or LIFEPAK 20e?
Not through any Stryker-listed path. The LIFEPAK 35 and LIFEPAK 20e guides list LNCS adhesive sensors, such as the adult 11171-000019, and no M-LNCS sensor.1415 The 2508 has the M15 connector, which Masimo's chart marks not for LNC or Red LNC cables.5 On those monitors use the LNCS Adtx (1859).
Can the Masimo 2508 go on a large child, or do I need the Pdtx?
The 2508 is labeled for patients over 30 kg. The pediatric Pdtx covers 10 to 50 kg, so a child from 30 to 50 kg fits either size, and a child from 10 to 30 kg takes the pediatric sensor, 2510 (18 in) or 2511 (3 ft); a child under 10 kg takes an infant sensor.1
Where does the Masimo 2508 go on a patient, and how often do I check the site?
Use the middle or ring finger of the non-dominant hand; a toe is the other labeled site.1 Place the fingertip on the dashed line with the pad over the detector, fold the sensor so the red star sits over the nail, and line up the black marks. Inspect the site at least every 8 hours, or hourly on a poorly perfused patient.1
Can I tape down or reapply a Masimo 2508 that keeps lifting?
Do not add tape: it can restrict blood flow and give inaccurate readings.1 An adult sensor can go back on the same patient while the windows are clear and the adhesive holds. Adhesive tabs come only with infant and neonatal sensors, so when it fails, use a new sensor.1
Why does the monitor show replace sensor or no reading with the Masimo 2508?
Replace the sensor when a replace sensor message shows, or when a low SIQ message stays after the monitor's low SIQ steps.1 Check that the connector is fully in and locked, the pad covers the detector, and the site is at heart level and clear of a cuff or arterial line. Nail polish, dyes and high ambient light also disturb readings.1
