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.

Cabinets: Wall Mounted NEMA7 UL/CSA Class1 Div1 Explosion-proof sensor cabinet, with NEMA4 wall-mount control cabinet (two separate cabinets)
Unit of Measure

Features

N/A

  • Detector is temperature-controlled or compensated for improved analytical stability and fast response
  • PPM range CO measurement by electrochemical sensor
  • Touch-screen display for gas readings
  • Built-in sample pump or pressure regulator
  • Non-isolated 4-20mA analog recorder output

Options

N/A

  • Hi/Low gas and low flow alarms available

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.
