Zacurate 500DL Pro Series Fingertip Pulse Oximeter review

The Zacurate 500DL Pro Series is the budget pick for anyone who just wants a number now and then. It costs $19.99 on Zacurate's own store, and Zacurate says it measures SpO2 and pulse rate within 10 seconds with plus or minus 2% accuracy between 70% and 99%. The Pro Series version reads up to 100% and has an LED screen that faces the user. A spring-loaded silicone finger chamber is hypoallergenic and latex-free, and the box includes 2 AAA batteries, a lanyard and a silicone cover. Zacurate backs it with a 1 year warranty and USA-based phone support and sells it with quantity discounts. What you give up is everything beyond the two numbers: no app, no waveform, no alarm, and Zacurate lists it for ages 12 and up. For an alarm and waveform, the 500C Elite costs $36.99.
