Item # Model 430RMN7, Model 430RMN7, Hydrogen Analyzer, ex-proof sensor housing with rack mount control cabinet (two separate enclosures)


The Nova 430 Series Process Hydrogen analyzer utilizes a temperature-controlled TC cell for the detection of H2 in process gas. This cell produces a small millivoltage output which is directly proportional to the H2 detected. This output is then amplified and displayed on a digital readout meter and is also available as an output recorder. The analyzer can be supplied with a pump or pressure regulator depending on customer requirement.

Cabinets: Wall Mounted NEMA7 UL/CSA Explosion-proof sensor cabinet with 19" rack mount control cabinet (two separate cabinets)
