You are looking at a NEW IN BOX re-usable Masimo Set Ear Clip Spo2 Sensor. Sensors must be repositioned every 4 hours. The LNCS TC-I, or Low Noise Cabled Sensors, are uniquely designed cabled sensors, which offer the best pulse oximetry performance for a sensor with integral cable. LNCS is intended for hospitals that prefer to minimize clinician-user-interface change when upgrading their pulse oximetry to Masimo SET. Masimo has invested years in creating Low Noise Cabled (or LNC™) technology, the ideal cable for the pulse oximetry environment. LNC provides the highest performance of any integrated pulse oximetry sensor cable and yet is flexible and can be manufactured affordably enough to be used in a disposable sensor. LNCS sensors will work with all Masimo SET pulse oximeters, but are also designed to operate on Nellcor sensor compatible instruments without Oximax.
