About this item

• 
  ACCURATE OXYGEN SATURATION AND PULSE RATE READINGS IN ONE DEVICE: The
  Fingertip Pulse Oximeter fits all finger sizes from kids above four
  years old to adults as it measures the level of oxygen in the blood and
  reads the pulse rate in just eight to ten seconds. It is crucial to use
  the device in a stationary position and not while in motion for precise
  readings.
  
  
• 
  LOW POWER CONSUMPTION: Equipped with two AAA batteries, the oximeter
  automatically powers off when not in use and delivers up to 20
  continuous hours of battery life.
  
  
• 
  PORTABLE AND LIGHTWEIGHT: Weighing only 50 grams, every AccuMed oximeter
  comes in a convenient travel case that protects it from scratches when
  carried on its own or inside your gym bag or backpack. Attach the
  included lanyard to the case or directly to the oximeter for easy reach
  anytime.
  
  
• 
  ROTATING, CRYSTAL CLEAR LED DISPLAY: Read your oxygen saturation level
  and pulse rate results with remarkable clarity in portrait or landscape
  formats with auto rotation that detects your hand movement in the
  CMS50D1 models.
  
  
• 
  DESIGNED FOR HOME USE, EXERCISE OR TRAVEL: While the AccuMed Fingertip
  Pulse Oximeter is handy for detecting vital signs, it is not intended
  for medical use but rather for situations where you need to know your
  oxygen level before and after your workout or sports such as running,
  hiking or cycling, or while traveling in an aircraft.
