How Accurate is the Zacurate 500DL Pulse Oximeter?

The Zacurate 500DL has been praised for its accuracy, with 95% of users reporting reliable SpO2 and pulse rate readings. According to CNET's testing, it performs well within the expected range for non-medical pulse oximeters. Customers often use it to monitor their oxygen levels during physical activities or at home, finding the results consistent with professional devices. However, 2% of reviewers noted occasional discrepancies, which they resolved by recalibrating the device or ensuring proper finger placement. Compared to competitors like the Wellue O2Ring, which is more expensive but also offers continuous monitoring, the Zacurate 500DL provides a cost-effective solution for spot-checking oxygen levels.

The Masimo MightySat, at $300, provides medical-grade accuracy and additional features like perfusion index, making it suitable for more serious health monitoring.
