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 plastic face to protect from sick room spills. The switches are a new membrane style, which are a low profile design with no sharp edges to get caught or inadvertently triggered. The case also has a handy clip to attach to your belt or lab coat pocket and an adjustable carrying strap if you prefer putting it over-the-shoulder. The battery is pre-installed and the PRO2 Check® is ready to go right out of the box! 


The unit has a 2-year warranty.

 *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.
