The MRU NOVA Plus Combustion Gas Analyzer can simultaneously measure up to eight gas components. Its built to meet the most stringent requirements. The NOVA Plus provides fast accurate of all gas, oil and solid fuel combustion's. It's also suitable for CHP's (co-generation heat and power engines). The NOVA Plus Combustion Gas Analyzer comes standard with an O2 sensor (0 to 25%) and a CO (H2 compensated) sensor 0 to 10,000 ppm.

The NOVA Plus Emission Analyzer is built with a robust metal enclosure mounted inside an aluminum framed case. Its low weight and size make it easy to transport. The O2 long life sensor has an expected life time of 4-5 years. The NOVA Plus is provided with a built-in printer with easy paper loading. The units also measure gas/air temperature, differential pressure and stack draft.

  • CO; 0 to 4,000 ppm
  • CO2; single NDIR 0 to 20%, tripple NDIR 0...3% up to 30%
  • O2; 0 to 21 Vol-% abs.
  • NO; 0 to 1,000 ppm
  • NO2; 0 to 200 ppm
  • NO(x); True NOx using NO and NO2
  • SO2; 0 to 2,000 ppm
  • H2S; 0 to 200 ppm
  • C3H8; tripple NDIR Bench, 0…..2,000ppm up to 5,000 ppm
  • CH4; tripple NDIR Bench, 0…..10,000ppm up to 3%
  • Fluegas temperature; less than/equal 1,200°F (650°C), less than/equal 2,000°F (1,100°C)
