Item # Model 480RMN7, Model 480RMN7, Carbon Monoxide Analyzer, ex-proof sensor housing with rack mount control cabinet (two separate enclosures)


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 19" rack mount control cabinet (two separate cabinets)

Low flow alarm

Analyzer Type
CO Analyzer (ppm)

Hazardous Area Rating Options
Control Cabinet - General Purpose, Non-Hazardous
Detector Cabinet - NEMA7 Class 1 Division 1 Groups BCD


Applications
For continuous analysis of up to 0-10,000 PPM carbon monoxide (CO) in process gas streams using an electrochemical detector.


Features
  • 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
  • Hi/Low gas and low flow alarms available
  • Serial output & data-logger package available


Calibration
  • Nitrogen for zero.
  • Analyzed ppmCO calibration gas for span.


Unique Applications
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.
