Innovo Deluxe iP900AP Fingertip Pulse Oximeter vs Masimo MightySat Rx Fingertip Pulse Oximeter
Which should you buy? Our verdict on both, 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: it packs an OLED display, waveform, and perfusion index into a self-contained clip at a mid-range price. Step up to the Masimo MightySat Rx only if you need a reading aimed at difficult conditions and are willing to pay flagship money for Masimo SET signal processing.

Innovo Deluxe iP900AP Fingertip Pulse Oximeter
Buy itThe value pick, a self-contained clip with a waveform and perfusion index at a mid-range price.
- Owners and reviewers generally rate it well for everyday use and ease of use
- An OLED screen shows SpO2, pulse rate, a plethysmograph waveform, and perfusion index
- Simple one-button operation and a self-contained design make it 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 itA consumer clip built on Masimo SET signal-extraction technology, aimed at difficult conditions.
- Built on Masimo SET signal-extraction technology, which Masimo positions for use during movement and low blood flow
- Reports perfusion index, with further metrics on some configurations, on a display built for easy reading
- On the Bluetooth LE-equipped model, the Masimo SafetyNet app makes it easy to view trends and share them with a clinician
- Costs considerably more than the other clips 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 may be limited to the pricier configurations
