CMS-50 QB Pediatric Fingertip Pulse Oximeter with Alarm

The CMS-50 QB Pediatric Pulse Oximeter is a rechargeable activity monitoring device that is compact and portable. The meter’s SpO2 and pulse rate readings display on the built-in color OLED screen. The CMS-50 QB detects the user’s custom upper/lower limit measurement thresholds that automatically activate the monitor’s alarm. A single button on the finger oximeter allows the user to adjust settings and manage all other device operations.

A pulse indicator is available within the device settings that emits a tone for pulse rate tracking. The sensor’s readings also update in real-time as a bar graph or waveform animation. The auto shut-down feature turns the monitor off within a few seconds of inactivity for power-saving.
