The Nova 436 Series Tri-gas analyzer is designed specifically for monitoring H2 purity in a power generator and to monitor the purging procedure during shut down. The analyzer can measure the following gases by switch selection: Range 1: 0-100.0% H2 in AirRange 2: 0-100.0% H2 in CO2Range 3: 0-100.0% Air in CO2A 4-20mA recorder output is provided for the range of 85-100% H2 in Air. The Model 436 analyzer is typically available in a single ex-proof cabinet with all capabilties built-in. Or, it may be divided into 2 sections that are electrically connected. The control section contains the main microprocessor boards as well as the touch-screen display, alarm contacts, and calibration & function switches. The gas detector section contains the temperature controlled thermal-conductivity (TC) cell, solenoid valves, gas pressure regulator, flow meter, and 2 flame arrestors. Either the gas detector section on its own or both gas detector and control sections may be purchased in explosion-proof cabinets. The explosion-proof cabinets are UL listed and CSA certified for use in Class 1, Division 1, Groups BCD hazardous areas. If the gas detector section only is explosion-proof, the control section is typically enclosed in a 19" rack mount cabinet for use in a general purpose, non-hazardous area. The control section can also be mounted in a NEMA 4 wall mount cabinet.Cabinets, 436N4N7: Gas Detector in Class 1, Division 1, Groups BCD Explosion-proof Cabinet; Control Section in General Purpose NEMA 4 Cabinet
