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)
