Product Description

500BL_Header
500BL Product Hero Image

What information should I know about the Zacurate 500BL Pulse Oximeter to ensure I get accurate readings?

In the product details section of this webpage, please refer to the application guide, product documentation, troubleshoot guide and quick start guide for important details to know before using this item and ensure the item gives accurate readings.

Does movement of any kind affect the product's ability to provide an accurate reading?

Yes, movement of any kind can lead the device to display inaccurate readings. It is important to use the device as specified in the application guide, product documentation, troubleshoot guide and quick start guides.

What are normal oxygen saturation levels?

The normal reading for blood oxygen is typically in the 95-100 range. However, there are certain conditions where this may not apply. Your doctor will be in the best position to advice where your readings should be.

Can I check my readings while I am exercising?

Any movement can cause the device to reset its readings. If you are in the middle of exercising, we advise to take readings during resting phases while the body is not mobile. If you have finished, wait 10-15 minutes before taking a reading.

Why does the reading fluctuate and why is the reading different on different fingers?

It is normal and natural for your SpO2 and Pulse rate to fluctuate as the amount of arterial blood pulses and changes with each heartbeat. A ±3 fluctuation in your SpO2 is considered normal.

Looking for a reliable BPM / Pulse Oximeter? I'd say this one.
As a personal trainer and fitness enthusiast, I was interested in getting a an external device that could help me monitor both myself and my clients heart rate. Didn't care too much about the pulse oximeter reading Because my main objective was more so to gain more heart rate and BPM data. Upon cross referencing this heart rate data with my series 6 Apple Watch, I was considerably impressed with the consistency in results. I found that my Apple watch is fairly close in readings to the gym equipment at the gym that I attend. The cardio equipment such as the elliptical and the treadmill has built in heart rate monitors using hand grip sensors. I often double check to make sure these monitors and sensors have the same readings that my Apple watch does and to my surprise they are actually quite similar. The accuracy of these numbers I'm not too sure, but I do know that the variability in readings is low and your data will be relatively consistent. I opted for this product because of the way it looked as far as sturdiness design and overall quality. I just received this product today in the mail and I tested it once in a rested state once during my workout and once post workout all three readings were within 2-4 BPM of my Apple Watch.5/5 - We'll see how it works for the long term and after many uses. All it requires is 2 AAA batteries (which came included), but I chose to use my own Duracell batteries which I've experienced to work better in most electronics.
