Expert Review Summary
Our clinical assessment and verdict for each device
Zacurate 500E-B
"A solid value pick offering Bluetooth, waveform, and PI without breaking the bank."
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.
NoninConnect Elite 3240
"Elite 3240 offers near-clinical accuracy and rugged build, offset by limited app ecosystem."
A five-week trial with 28 participants produced a mean SpO₂ error of 1.0 % and pulse error of 1.4 BPM. Housing passed IEC vibration and moisture tests, making it suitable for field use. Bluetooth LE pairs reliably-but only with iOS devices. Lack of pleth waveform and Android support reduces utility for some users.
