The SONOSAT-W01LT is a watch-type, portable pulse oximeter and activity monitor that measures SpO2 and pulse rate, tracks steps and sleep, displays time like a wristwatch, features a rotatable screen, and supports a companion mobile app via WiFi.
It measures blood oxygen saturation (SpO2) and pulse rate, provides comprehensive sleep analysis (including sleep apnea levels, oxygen deficiency, sleep quality index, and effective sleeping time), and tracks step count and basic activity metrics.
SpO2 range: 0–100%, resolution 1%, precision ±2% in the 70–100% range, data update every 1 second. Pulse rate range: 18–250 bpm, resolution 1 bpm, precision ±3 bpm (range 25–250 bpm), data update every 1 second.
SpO2 and pulse rate measurements update every 1 second, providing near real-time readings.
Wear it snugly on the wrist with the sensor in full contact with the skin. Keep your hand still and relaxed during measurement and avoid excessive motion for best accuracy. Follow the placement and fitting instructions in the user manual.
The device's display orientation can be adjusted to improve visibility and comfort while worn on the wrist. It also shows the current time, allowing it to function as a regular wristwatch in daily use.
The device records oxygen saturation and pulse trends overnight to generate sleep reports that estimate sleep apnea levels, oxygen deficiency during sleep, a sleep quality index, and effective sleep time. Detailed reports are viewable in the companion app.
The device is rated IPX1, meaning it is protected against vertically falling water drops (drip resistance). It is not designed for swimming, showering, or immersion—avoid heavy splashes or submersion.
The SONOSAT-W01LT supports a companion app and connects via WiFi for data synchronization. The app (available for major mobile platforms—check the product packaging or app store listing) displays measurement history, sleep reports and activity data. Follow the quick start guide for WiFi pairing and app setup.
The companion app is intended for common mobile platforms (iOS and Android). Compatibility details, required OS versions and app download links are provided in the product documentation or the app store listing—check those sources before purchase.
Measurements sync to the companion app via WiFi, where you can view trends and reports. Export or sharing options (CSV, PDF or cloud sync) depend on the features of the specific app—refer to the app settings and documentation for available export and sharing functions.
The device is designed for personal and general health monitoring and the description indicates it complies with relevant product qualifications and licenses for applicable countries. However, it should not replace professional medical advice or diagnosis. For clinical decisions, consult a healthcare professional.
Accuracy can be affected by movement, poor peripheral perfusion (very cold skin), excessive ambient light on the sensor, incorrect fit or placement, and certain medical conditions. For reliable results, wear the device correctly and remain still during measurements.
Do not immerse the device in water. Wipe the housing and sensor gently with a soft cloth slightly dampened with mild soap solution or approved disinfectant wipes. Avoid strong solvents or abrasive cleaners. Follow the manufacturer’s maintenance guidelines in the user manual.
