Contec Medical have established themselves as a world leader in small medical devices and home monitoring equipment, due to their high accuracy, reliability, and value for money. The Contec CMS50DL fingertip pulse oximeter reflects these core values, and answers the physician, clinic, home health care, sports and aviation markets’ demand for a lightweight, inexpensive monitor for measuring SPO2 oxygen saturation (%SpO2) and heart rate (pulse).

Its long battery life (2500 spot checks, or 30 hours of continuous use) makes this a particularly popular model for health care workers on the go, as well as paramedics and police offers.

1 year manufacturer’s warranty and set of AAA batteries included.

The CMS50DL’s accuracy of +/- 2% is the industry standard (Ingram & Munro, 2005). Many oximeters are less accurate than this, but it is important to note that more expensive oximeters are not more accurate; the higher pricing comes from durability and drop-testing. Unless your oximeter is going to be used in an environment where it is repeatedly dropped from a height, the CMS50DL has all of the features you will ever need in an fingertip pulse oximeter. It is also one of the most reliable models on the market, and is backed by a 2-year manufacturer’s warranty.
