The Nova 410 Series represent Nova's best value in continuous process O2 analysis. This analyzer utilizes a long-life electrochemical 'fuel cell' sensor for the detection of Oxygen 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 can also be sent to an optional recorder output. The 410 can be supplied with sampling pump or pressure regulator to suit most applications.
