Item # Model 430N4, Model 430N4 Hydrogen Analyzer, Wall Mounted NEMA4 (IP65) Enclosure Rating

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.

Depending on application, some light-duty sample conditioning features may be available. For clean process measurements, percent-level H2 gas. This analyzer utilizes a temperature-controlled, thermalconductivity (TC) cell for the detection of H2 in process gas. The cell produces a small millivoltage output which is directly proportional to the H2 detected. The analyzer can be supplied with a pump or pressure regulator depending on customer requirement.

All sensors / detectors are temperature-controlled or temperature-compensated for maximum analytical stability. Easy calibration using touch-screen controls. Serial Output Package allows local USB connection & data-logging to personal computers.


Cabinet: NEMA 4 Weather-proof steel cabinet with window
