The Nova FLEXI-NOVA Series Platform has been designed for continuous gas measurements in applications and environments that are less intensive. Lab work, research, clean processes, pre-treated / pre-cleaned produced gases, and others, may benefit from the FLEXI-NOVA series.

For clean process measurements of ppm-level CO gas using an electro-chemical sensor. All sensors / detectors are temperature-controlled or temperature-compensated for maximum analytical stability. Easy calibration using touch-screen controls. Serial Output Package allows connection & data-logging to personal computers via a choice of USB / RS-232 / RS-485.



Cabinet: NEMA 4 cabinet with Hazardous Area Purge System; available for Class 1 Div1 or Class1 Div2 hazardous areas

Unique Applications

N/A The electrochemical CO sensor is unsuitable with certain background gases such as hydrogen. Also, this cell requires that a small amount of O2 be present in the sample, or that it be metered into the sample. Consult Nova for each application.
