A solid value pick offering Bluetooth, waveform, and PI without breaking the bank.
Zacurate 500E-B Review: Budget Bluetooth with Surprising Precision
In a four-week test with 22 participants, the 500E-B showed mean SpO₂ error of 2.6 % and pulse error of 2.0 BPM. OLED presents waveform and perfusion index, rare at this price. Plastics feel light, and battery door loosened after 30 drops. The Beyond Oximeter app syncs trends but lacks export options.
