The Nova 413 Series process analyzers utilize a long-life zirconia sensor for high accuracy detection of O2 in process gases. The sensor produces a small millivoltage output which is directly proportional to the Oxygen detected. The output is then linearized and displayed on a digital readout meter and can also be sent to an optional recorder output. The 413 can be supplied with sampling pump or pressure regulator to suit most applications. High and low range versions of this analyzer are available - denoted as models 413 and 413L respectively.
