The newly upgraded Zacurate CMS 500DL Generation 2 Fingertip Pulse Oximeter can now read SpO2 up to 100%! Designed for sports enthusiasts, pilots or anyone who wants to obtain their SpO2 (Blood Oxygen Saturation Levels) and PR (Pulse Rate) on the go, the measurement now faces instead away from the user. We have also upgraded many internal components of the pulse oximeter. Taking a reading is easy, just clip it on to your finger and turn it on at the press of a button. The large LED display makes viewing the results a snap. Its small size makes it easy to carry around and a lanyard is also included for added convenience. Comes with 2 AAA batteries and a silicon cover to protect your pulse oximeter from dirt and damage.

We have recently change our brand name from Acc U Rate to Zacurate. Please note that Zacurate is a registered trademark of USPTO.

Zacurate Pulse Oximeter is designed in USA.

  • ACCURATE AND RELIABLE - The Zacurate 500E Pulse oximeter is the premium model of the Zacurate line of pulse oximeters. With a vastly improved LED and sensor, it allows SpO2 (Blood Oxygen Saturation level) and pulse rate measurement even at low blood perfusion.
  • MEET & EXCEED FDA STANDARDS - Designed for sports enthusiasts like mountain climbers, skiers, bikers or people interested in measuring their SpO2 and pulse rate.
