Salter Labs® Ultrasonic Oxygen Indicator Quickly and accurately determines percentage of oxygen delivered by O2 concentrators. ¸ No expensive fuel cells to replace ¸ No need for time consuming, routine calibration ¸ Easy set up, use, and maintenance ■ Accurately measures oxygen concentration from concentrators ■ Allows providers to quickly & easily determine if units are delivering optimal O2 concentrations ■ Uses microprocessor controlled ultrasound technology to indicate oxygen concentration ■ Highly accurate measurements with no maintenance costs ■ No expensive galvanic fuel cells to replace ■ Economical to own, costs virtually nothing to operate ■ No need for routine calibrations* ■ Saves time and money ■ Maintains calibration with altitude and temperature variations ■ No need to recalibrate for minimal temperature or altitude changes ■ Calibration can be quickly & easily verified with one button ■ Allows providers to conform to calibration requirements of accreditation bodies (if required), or any internal corporate operating policies and procedures ■ Operates with standard 9 volt alkaline battery ■ Readily available battery can be easily changed without tools ■ Connects to concentrator with simple oxygen supply tubing, plus has large digital display ■ Saves time; easy to use and read in the field ■ Attractive carrying case included with unit ■ Convenient to clip on belt or use with shoulder strap and protects ruggedly designed instrument *Since the PRO2 check® device is completely electronic and does not have the same characteristics as a unit with a fuel cell, there is no recommended calibration schedule.

Salter PRO2 check® Ultrasonic Oxygen Indicator Inspired by the oxygen measurement system found inside many oxygen concentrators, the PRO2 check® ultrasonic oxygen indicator is a breakthrough product that uses microprocessor controlled enhancements of a proven technology to indicate oxygen concentration. The PRO2 check® uses ultrasound technology which accurately measures the speed of sound through various gases. This new method of indicating gas concentration offers many superior benefits over the more familiar analyzers powered by galvanic fuel cells. It comes in a carrying case with a clear...
