Home health monitors: blood pressure, pulse oximeters and thermometers (2026)
A blood pressure monitor, a pulse oximeter and a good thermometer let you keep an eye on someone at home during an outage, a storm or a bout of illness, and give a doctor or nurse real numbers on the phone. This page compares home models on the thing that matters most: whether there's any independent check of their accuracy. Every spec is from the maker, read on the date in each card's notes; we haven't used these ourselves. These are monitoring tools, not a diagnosis: if you're worried about a reading or how someone feels, contact a health care provider, and call 911 in an emergency.

Our verdictOur verdictResearched A quick ear thermometer that colors its screen green, yellow or red with age-adjusted fever guidance, and beeps when it's positioned right. It remembers the last nine readings, which helps when you're tracking a fever overnight or reporting to a nurse line. It needs disposable lens filters. Best for Families with young children Good

Fingertip pulse oximeter · Sold for sports and aviation (maker): not FDA-reviewed · None · 2 x AAA (included) A low-cost spot check, understood as an estimate | Fingertip pulse oximeter | Sold for sports and aviation (maker): not FDA-reviewed | None | 2 x AAA (included) | |
Our verdictOur verdictResearched Its maker is upfront that it's sold for sports and aviation, which the FDA says means it doesn't go through FDA review. It reads in about 10 seconds and comes with batteries and a cover. Use it for spot checks and trends, don't rely on it alone, and follow the FDA's advice to contact a health care provider if a reading worries you. Best for A low-cost spot check, understood as an estimate Good
Worth knowing
Who shouldn't buy it: Don't buy it if a doctor has asked you to monitor oxygen for a medical condition: ask them which oximeter to use. | |||||
Fingertip pulse oximeter, plethysmograph and perfusion index · Maker page conflicts (see notes) · None · 2 x AAA (included) Spot checks with a waveform and an alarm | Fingertip pulse oximeter, plethysmograph and perfusion index | Maker page conflicts (see notes) | None | 2 x AAA (included) | |
Our verdictOur verdictResearched A fingertip oximeter with a waveform display, which helps you see whether it's getting a clean reading, and an alarm you can set for high or low readings. Innovo's page is contradictory: it calls the iP900AP 'FDA Cleared' but also says it's for sports and aviation use only, and gives no 510(k) number. Innovo also says it isn't for overnight monitoring. Best for Spot checks with a waveform and an alarm Good

Who shouldn't buy it: Don't buy it if you need overnight oxygen monitoring: Innovo says this can't do it. | |||||
Digital stick thermometer · See the maker · Not confirmed by maker · Not confirmed by maker A cheap, simple thermometer for the emergency kit | Digital stick thermometer | See the maker | Not confirmed by maker | Not confirmed by maker | |
Our verdictOur verdictResearched A basic digital stick thermometer with a color-coded screen and a reading in about 8 seconds (retailer). It has no filters to buy, which makes it a good spare for a go-bag or the car kit even if you own an ear thermometer. Best for A cheap, simple thermometer for the emergency kit Good
Worth knowing
Who shouldn't buy it: Don't buy it if you need fast readings on a squirming toddler: an ear or forehead thermometer is quicker. | |||||
Fingertip pulse oximeter · No FDA clearance stated · None · 2 x AAA (included) The cheapest basic spot check | Fingertip pulse oximeter | No FDA clearance stated | None | 2 x AAA (included) | |
Our verdictOur verdictResearched Zacurate's basic model, the older sibling of the 500DL. It only shows oxygen up to 99% and the screen faces away from you, which the 500DL fixes. Like the 500DL, no FDA clearance is stated, so don't rely on its readings alone. Best for The cheapest basic spot check Good
Worth knowing
Who shouldn't buy it: Don't buy it if you can stretch to the 500DL: its display faces you. | |||||
ⓘ As an Amazon Associate, PreparedStates earns from qualifying purchases. We may earn a commission when you buy through our links.

Before you buy
Blood pressure
Pick a monitor on the US Blood Pressure Validated Device Listing (validatebp.org), run with the American Medical Association, which lists monitors that have been checked for clinical accuracy. Every OMRON monitor here is on OMRON's own list of its models on that listing; Amazon listings often don't show the model number, so check the box.
Cuff size matters: the OMRON upper-arm cuffs here fit arms 9 to 17 inches around.
Measure your upper arm before you buy.
Upper arm or wrist
OMRON's wrist model guides you to hold your wrist at heart level, the proper height for consistent readings. An upper-arm monitor avoids that step.
Pulse oximeters: the FDA splits them into prescription and over-the-counter.
OTC oximeters intended for medical purposes need FDA authorization; those sold for general wellness or sports and aviation don't undergo FDA review. Check the maker's page or the box for which kind you're buying.
Don't rely on one oximeter number alone.
The FDA says changes or trends over time may be more meaningful than one single reading.
Thermometers
An ear or forehead thermometer is quick for children who won't sit still; a basic digital stick thermometer is cheap and simple, with no filters to buy.
Batteries: all of these run on ordinary AA, AAA, 9V or button batteries.
Keep spares in your emergency kit, since an outage is when you may need them.
We verify every product's specifications against at least two independent sources, re-check its US price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labeled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test. When two products are close, commission can decide which one we pick. A clearly better product always wins. Read our full methodology →

Common questions
Are pulse oximeters accurate on darker skin?
The FDA says skin pigmentation is one of several factors that can affect a pulse oximeter reading, and it has been looking at concerns that oximeters may be less accurate in people with darker skin pigmentation. It says not to rely only on a pulse oximeter, to watch your symptoms, and to contact a health care provider if you're concerned.
How do I know a blood pressure monitor is accurate?
Check the US Blood Pressure Validated Device Listing at validatebp.org, which lists monitors checked for clinical accuracy. OMRON publishes which of its models are on it; all the OMRON monitors on this page are.
Is a wrist blood pressure monitor as good as an upper-arm one?
A validated wrist monitor can be used, but readings depend on holding your wrist at heart level. OMRON's wrist model has a guide for this. If an upper-arm cuff fits you, it removes that step.
Are cheap fingertip oximeters FDA-cleared?
Not always. The FDA says OTC oximeters sold for general wellness or sports and aviation don't undergo FDA review, while OTC oximeters intended for medical purposes need FDA authorization. Check how the maker describes the one you're buying.
Why keep these in an emergency kit?
During an outage or a storm, getting to a clinic can be hard. Readings you can give a doctor or nurse over the phone help them advise you. They don't replace calling 911 in an emergency.
