Pulse Oximeter

The Model 7500 pulse oximeter has a low-profile design that fits easily on a tabletop or in its own carrying case. Well suited for a variety of clinical and homecare applications, the compact 7500 features simple functionality, minimum 16-hour battery life, 4-hour quick recharge, and a minimum of 70 hours of memory. Like all Nonin portable oximeters, the 7500 provides reliable readings and a wide variety of display indicators.

The 7500FO (fiber optic) pulse oximeter is specifically designed for MR environments. It can be used in fixed-site or mobile MR facilities for monitoring infant, pediatric, and adult patients.
