DE-OX BIO Carbon Dioxide Analyzer

Carbon dioxide (CO2) is a colorless and odorless gas, that is often found in engine exhaust. The DE-OX BIO is an analyzer based on an innovative non-dispersive infrared (NDIR) temperature compensated carbon dioxide sensor. The sensor has the same shape, dimension and thread of the most common oxygen sensors. Before diving, DE-OX BIO is able to analyze the carbon dioxide content in every breathing gas mix, including air. It can be connected to a gas or diesel high or low pressure compressors for in-line continuous monitoring of gas quality.
