Medical professionals or home users with a Criticare 934-10DN pulse oximeter – if the finger sensor (the clip part) is broken, worn out, or giving erratic readings, this is a direct replacement. It's an adult-sized finger clip sensor from ALPTA, model SP073A. It has a 6-pin connector that should plug right into your Criticare 934-10DN monitor. Brand new in packaging. These sensors are consumables; the cables can fray, the LEDs can fail, or the clip mechanism can break. Replacing it restores accurate blood oxygen (SpO2) and pulse rate readings. No UPC listed. Essential for ensuring your oximeter is providing reliable data for patient care or personal health monitoring. Make sure your monitor model matches before ordering. A simple swap to keep your medical equipment functional.
