Pulse Oximeter — Real-Time Blood Oxygen & Heart Rate Monitoring

Three breakthroughs that set it apart

• Imported chips + AI algorithm = clinical‑grade accuracy

  Unlike generic devices, the LK88 uses professional sensor chips and onboard AI to eliminate motion artifacts and environmental noise — delivering SpO₂ and heart rate numbers you can trust at home, in the gym, or while travelling.

• Instant low‑oxygen alarm with sound & light

  Set it and forget it. When your SpO₂ dips to ≤95%, the device flashes and beeps — so you can respond immediately, day or night. Perfect for elderly care, sleep apnea monitoring, or post‑surgery recovery.

• Silicone light‑shield for consistent readings

  A custom silicone cap blocks ambient light that can confuse lesser sensors — meaning accurate results whether you’re outdoors, in a bright room, or using it under a blanket.

3 seconds to your first reading

1. 1
   Insert one finger

   Place your index or middle finger into the soft silicone chamber, nail facing up and fingerprint down over the sensor window.

2. 2
   Press the button

   A short press powers on the OLED screen and starts the measurement. Keep your hand still for the next 8 seconds.

3. 3
   Read your numbers

   SpO₂ (oxygen saturation) and heart rate appear in large digits, with a pulse intensity bar and oxygen reserve ring underneath.

4. 4
   Know the alarm

   If your SpO₂ drops to ≤95%, the device beeps and the screen flashes — you can’t miss it. Press any button to silence.

5. 5
   Power off or let it auto‑sleep

   After 8 seconds of no finger, the LK88 automatically powers off to save battery. For continuous monitoring, just keep a finger inserted.

From silent worry to measurable calm

The quiet threat of undetected hypoxemia

Without regular monitoring, oxygen levels can dip dangerously low — especially during sleep, high altitude, or recovery. The LK88’s automatic alarm triggers at ≤95% SpO₂, giving you a safety net when you need it most.

Engineered for clinical accuracy you can trust

Inside, professional‑imported sensor chips work with an AI algorithm to filter out noise — just the sort of precision you’d expect from a medical device. The result? Readings you can act on without second‑guessing.

Your personal health assistant in the palm of your hand

Compact enough for your gym bag or bedside table, the LK88 slips onto a finger and reads in seconds. The OLED screen shows SpO₂, heart rate, pulse intensity, and an oxygen reserve indicator — so you always know exactly where you stand.

Simple care for years of accurate readings

• Clean after each use

  Wipe the silicone chamber and sensor window with a soft cloth lightly dampened with 70% isopropyl alcohol. Avoid abrasive cleaners.

• Keep dry

  Never immerse in water. If moisture gets inside, remove batteries and let air‑dry completely.

• Replace batteries when low

  When the battery icon shows on the OLED, swap in two fresh AAA batteries. Remove batteries if storing for more than a month.

• Store safely

  Keep in the included pouch or a clean drawer, away from direct sunlight and extreme heat.
