Forensics Detectors offers sensitive Oxygen Detectors & Analyzers. Verify oxygen (O2) purity from a oxygen cylinder, tank, scuba, veterinary incubator, confined space, personal safety, displaced oxygen, nitrogen flush, tanks, silos, inert leaks, and welding.
This is our Oxygen Analyzer Model O2BOX, accurate and easy-to-use for scuba, nitrox, diving, and testing levels from various sources such as oxygen machines and generators. It is made with extra-large buttons for easy use. This oxygen analyzer is made to detect the full range of O2 concentrations from 0% to 100%. The analyzer can be calibrated to air in less than 2 seconds with one-button calibration.
