The Roscid Technologies O2Tracer oxygen analyzer provides a simple, accurate and economical measurement of oxygen at trace and %-levels. Users can select their desired ranges between 100 to 10,000 ppm and 0 to 100% oxygen. The O2Tracer uses a micro-fuel cell to measure the oxygen concentration.

Calibration of the O2Tracer for trace oxygen measurements in gas should be done using a calibration gas. The concentration can be chosen freely within the measuring range. The O2Tracer can be calibrated with air for the percent range unit.

Other benefits of this meter include its compact size, inexpensive cost, long sensor life and IP65 enclosure. The O2Tracer also features reverse voltage protection and temperature compensation. Measuring corrosive gases with the O2Tracer is not recommended.
