Advanced Energy’s Andros® 6511 gas analyzer / non-dispersive infrared (NDIR) bench is individually calibrated for operation from 0 to 50°C over the range of specified concentrations. Results are stored within the system to provide accurate analysis.

After the initial warm-up, enhanced optics and electronics virtually eliminate zero drift  and feature precision-beam collimation. A comprehensive operating system allows you to tailor the device to multiple operations. And calculations are performed in realtime for transmission to your host system.


  • Measure up to five gases
  • Tailor to multiple operations without the need for a custom operating system
  • Nearly eliminate zero drift after the initial warm-up period
  • Meet all accuracy specifications
  • Exceed performance requirements for portable or fixed leak detectors of toxics or combustibles


  • RS232 output
  • Differential Pressure for flow monitoring
  • Low power
  • Fast response times
  • Precision-beam collimation
