Source: contecmedsystems.com (verified 2026-08-01) · corroborated by contechealth.com. CORRECTED: an initial aggregator search snippet claimed SpO2 accuracy of ±4%; the manufacturer's own showroom spec table (fetched directly) actually states '70%~100%: ±2%' as the primary declared accuracy, with '±4%' listed separately as the weak-signal/low-perfusion figure — both values are now captured, with ±2% used as spo2_accuracy_percent. The same source confirms pulse rate 30-250 bpm (±2 bpm or ±2%, whichever is larger), an LED display (no OLED, no Perfusion Index, no Bluetooth), 1.5V AAA×2 batteries rated for a minimum 24 hours continuous operation (up to a theoretical 56 hours), and CE/FDA clearance. It is a basic spot-check clip (no onboard trend memory), so continuous_monitoring is false. Price: $8.99 is what one eBay CMS50D listing shows; Contec's own current US storefront (contechealth.com) doesn't list the CMS50D by that exact model name but sells closely related low-cost LED-display siblings (CMS50M $9.99, CMS50NA $10.99), corroborating this device sits in the same sub-$15 price band rather than the $748 bulk-case figure that surfaced for a different (Nonin) product in this dataset. No release year found.
