Main features

  • Double thermal stabilisation: stabilisation of entire casing and of each NDIR sensor separately - such approach provides the best thermal stabilisation (accuracy to 0.01°C), short warm up time (30 ÷ 60min) and the best accuracy of the NDIR sensors
  • Up to 6 NDIR sensors, up to 3 electrochemical cells
  • Paired up with professional gas conditioner - PGD-100
  • Large - 6.4”, high-resolution - VGA (640x480) colourful display with touch-pad
  • PC-104 industrial class computer with Windows CE operating system
  • Advanced algorithms to control analyser's work, like warming up, compensation of cross-sensitivity values, response time - all which influence the quality and performance.
  • Measurement of many additional parameters: temperatures (ambient, gas), pressures (atmospheric, differential), flow velocity (with help of Pitot tube), flow control through device and more
  • Calculation of all combustion parameters like: stack loss, combustion efficiency,excess air coefficient, dew point temperature, and more
  • Communication with PC computer via RS232C and Ethernet interfaces
  • 2x USB port for connecting commercial peripherals (mice, keyboards) and Photon add-ons (analogue outputs / inputs)
  • Optional add-ons: analogue outputs (8-channels), analogue inputs (8-channels) modules
  • Optional portable printer
  • Results stored in database - possibility to view entire measurement session in graphical form, create measurement reports, export data to csv files, and more
  • Database for customers and objects informations
