New Call-to-action
The Nova 480 Series represent Nova's best value in continuous low range CO process analysis. This analyzer utilizes a long-life electrochemical 'fuel cell' sensor for the detection of CO in process gases. The sensor produces a small millivoltage output which is directly proportional to the oxygen detected. The output is then amplified and displayed on a digital readout meter and recorder output. The 480 can be supplied with sampling pump or pressure regulator to suit most applications.

Unique Applications

N/A

    Continuous analysis of CO by electrochemical cell requires that a small amount of O2 be present in the sample, or that it be metered into the sample. All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova. In many cases, we are able to build an analyzer specific.
