Item # Model 410RMN7, Model 410RMN7 Process Oxygen Analyzer, ex-proof sensor housing with rack mount control cabinet (two separate enclosures)

The Nova 410 Series represent Nova's best value in continuous process O2 analysis. This analyzer utilizes a long-life electrochemical 'fuel cell' sensor for the detection of Oxygen in process gases. The sensor produces a small millivoltage output which is directly proportional to the Oxygen detected. The output is then amplified and displayed on a digital readout meter and can also be sent to an optional recorder output. The 410 can be supplied with sampling pump or pressure regulator to suit most applications.

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