Innovo Deluxe iP900AP Fingertip Pulse Oximeter vs Masimo MightySat Rx Fingertip Pulse Oximeter
Which should you buy? Here's the honest call, pulled from our full The Best Pulse Oximeters: 4 Compared (and One to Skip) comparison.
For most people, the Innovo Deluxe iP900AP is the smart buy: independent testing rates its accuracy near the top of the field, and it packs an OLED display, waveform, and perfusion index at a mid-range price. Step up to the Masimo MightySat Rx only if you need the most dependable reading in difficult conditions and are willing to pay flagship money for hospital-grade signal processing.

Innovo Deluxe iP900AP Fingertip Pulse Oximeter
Buy itThe value pick that punches far above its price and topped more than one independent test round-up.
- Independent testing repeatedly ranked it at or near the top of the field for everyday accuracy and ease of use
- A crisp OLED screen shows SpO2, pulse rate, a plethysmograph waveform, and perfusion index, with six display orientations and adjustable brightness
- Simple one-button operation, an audible alert, and included batteries and lanyard make it genuinely grab-and-go
- No Bluetooth or app, so trend tracking means writing readings down yourself
- Takes one-time spot readings only and is not a substitute for a clinical-grade device

Masimo MightySat Rx Fingertip Pulse Oximeter
Buy itThe one consumer clip built on hospital signal-processing technology, and it shows when conditions get difficult.
- Built on Masimo SET signal-extraction technology, which independent testing and owner reports consistently rate as reliable during movement and low blood flow where cheaper clips wander
- Reports the widest data set, including perfusion index and, on higher configurations, respiration rate and pleth variability, with a bright, easy-to-read display reviewers frequently single out
- Bluetooth sync to Masimo's companion app makes it easy to log trends and share them with a clinician
- Costs several times more than every other clip here, which is hard to justify for occasional home spot-checks
- Owners note a short learning curve to seat the finger correctly, and the most advanced metrics live only on the pricier configurations
