The Zacurate Children Pulse Oximeter measures SpO2, pulse strength, and pulse rate in 10 seconds, has a 30-hour battery life, and over 1,500 reviews on Amazon.
Accurately monitoring your blood oxygen levels using pulse oximetry can be useful for a range of physical activities, such as hiking or cycling.
But how accurate is the Zacurate Children Oximeter, and is it worth buying?
In this review, we’ll guide you through the design features, customer feedback, warranty coverage, and how to achieve the most accurate readings.
We’ve also included comparisons with similar devices, to help you decide if this is the best pulse oximeter for children.
The Zacurate Children Oximeter is one of the few devices on the market that’s specifically designed for children between the ages of 2 and 12 years.
At the time of writing this review, it was also one of the more expensive, but the smaller clamp guarantees better accuracy than the loose fit you could get with standard pulse oximeters.
The display screen shows your Sp02 and pulse rate, in addition to a low battery indicator and plethysmograph. You can even rotate the screen to face different directions. This works particularly well for young children, where a parent or caregiver may need to view the results.
Having a plethysmograph means you can monitor the consistency of the child’s heartbeat. For best results, the height of the wave amplitude should be consistent throughout the reading.
It’s not a feature that’s found on most oximeters, but can be also be found on the Zacurate 430-DL and top-of-the-line Zacurate 500D.
But unlike the 500D, the Zacurate Children Oximeter has no audible alarm to alert you to high/low Sp02 and pulse rate readings.
As long as the finger and body are still, and the fingertip is warm enough, results are displayed within 8-10 seconds, which is standard for home oximeters.
How is it Powered?
The Zacurate Children Oximeter is powered by 2 x AAA batteries. This is the same as most of the top oximeters on the market.
Zacurate supply you with a set of batteries, but to enjoy the expected 40-hour battery life, we recommend using a new set. High-capacity rechargeable AAA batteries shouldn’t cost much more than $10-$12 for a pack of 8, which could save you money over time compared to alkaline.
Some devices offer different charging methods, such as USB, while others require no batteries at all. The Aupalla Oximeter, for example, connects directly to your phone for power and can display results on-screen.
However, connectivity for such devices is unreliable, and the readings fluctuate too much for us to ever recommend them in their current design.

Accuracy and Ease of Use
Tips for Accurate Pulse Oximetry
The most common reasons customers gave for lower review ratings on Amazon relate to accuracy.
That’s why we’ve added a quick guide for how to achieve the most accurate Sp02 and pulse readings with the Zacurate Children Oximeter:
- Ensure batteries are installed correctly
- Open the clamp
- Insert finger into the clip, with your fingernail facing upwards towards the screen
- Ensure your fingertip is directly in between the LED light source and LED sensor
- Release the clamp
- Press the button on front of the device once
- Keep finger and body still while the oximeter is taking its readings
What Should You Avoid?
Poor blood circulation can cause inaccurate or results. Warm your hands and fingers before taking the reading to increase blood flow.
The World Health Organisation (WHO) has also advised against wearing nail varnish or allowing bright light to enter the sensor. The color from nail varnish can absorb light from the oximeter and interfere with detection of oxygenated haemoglobin.
Certain medical conditions can also affect the accuracy of pulse oximetry. If you have hypotension, anaemia, tachycardia, hypothermia, or bradycardia, we recommend seeking advice from your physician.
A recent scientific study has shown that the highest Sp02 tends to be in the middle finger of the right hand. Conversely, the lowest is in the middle finger of the left hand, which is why we recommend using the same finger each time.

Who Are Zacurate?
Zacurate is a brand of pulse oximeters marketed by Med Shop & Beyond, alongside two Acc U Rate devices – the Acc U Rate 430DL and the Acc U Rate 500DL.
Med Shop & Beyond have several authorised dealers, through which they sell their pulse oximeters. Make sure to only buy from one of the following authorized dealers if you want a valid warranty: Amazon.com, Med Shop & Beyond, Evamedical, or Beyond Med Shop.
The main contact address for Med Shop is in Stafford, Texas, and many of the Zacurate oximeters have thousands of positive reviews on Amazon. This is due, in-part, to the excellent customer support.
What Do Other Reviews Say?
Our own oximeter reviews provide you with in-depth information and comparisons between the best devices.
But it’s also useful to check the feedback from as many people as possible, as not everyone has the same experience.
How easy was it to take a reading? Was customer service helpful and easy to contact? Were the readings accurate, and how comfortable was the fingertip grip?
The problem is, the best oximeters have thousands of reviews, and finding the most valuable information can be time consuming.
That’s why we did the leg work for you.
Listed below you’ll find a summary of the pros and cons for the Zacurate Children Oximeter, based on direct customer feedback.
- Excellent customer service from Zacurate – individually tested and calibrated a replacement device when customer experienced inconsistent readings
- Excellent accuracy for children. Most other oximeters on the market don’t fit the smaller fingers, leading to inaccurate results
- Useful for checking O2 levels. Although the general recommendation is for sports and not medical treatments, it’s also a useful indicator for whether children with asthma need a nebulizer or not, and whether blood oxygen levels are low enough to require a visit to urgent care
- Easy to use
- Bright display and large readings makes the results easy to read in low light
- Silicone cover helps minimize wear and tear when worn with the lanyard
- Design makes it more fun for children to use
- Shows the waveform of the readings so you can tell if the results are likely to be accurate
- Quiet to use – no beeping
- Useful if you have chronic obstructive pulmonary disease (COPD) and require supplemental oxygen
- More expensive than other home oximeter devices
- Some users report the reading taking up to 20 seconds, especially if there is movement
- Doesn’t have a multi-directional display option, which means it’s better suited to a caregiver taking the reading. This may work better for children anyway, who may be unlikely to take the reading on their own often
- Company states this device is for children aged 2 years and up, so not suitable for infants
- Has a hard time registering an accurate reading when blood perfusion level is low, but this is standard for most oximeters. If this is the case, good results were experienced by warming hands and waiting 30 seconds before attempting a new reading
