  • The Searchline Excel is the World’s best selling infrared open path gas detector with over 6,000 units installed in challenging applications throughout industry. From the Arctic Circle to Middle Eastern Deserts, customers have repeatedly selected the Searchline Excel as their preferred choice.

    The fundamental design of Searchline Excel has remained the same since its original launch and it continues to lead the field.

    The Honeywell Searchline Excel open path gas detector is totally immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning. Searchline Excel employs a patented double band pass filter that fully compensates for all types of fog and/or rain, thereby allowing it to continue to operate accurately and reliably in all climatic conditions.

    Brochure
  • • Fast speed of response provides earliest warning

    • High sensitivity allows low alarm set points

    • Patented double-band design ensures coverage in the most challenging conditions

    • Works in inert atmospheres

    • Response speed: T90 less than 3 seconds (under normal operating conditions)

    • Range: 0 to 5 LEL m.

    • Operating temperature: -40° to +65°C
  • Why open path gas detection?
    Open path detectors complement the use of individual point detectors and offer many significant benefits including:

    •  Wider area coverage – most likely to pick up any leak
    •  Very high speed of response
    •  NO unrevealed failure modes – no possibility of blocked gas path to detector
    •  Detector location not as critical
    •  Indicates size of hazard

    Sample and reference detector alignment

    •  Reduced sensitivity to alignment
    •  Guaranteed performance
    •  Reduced sensitivity to partial obscuration

    Improved hand-held software

    •  Simple confirmation of alignment
    •  Visual indication of target and current signal levels
    •  Compatible with existing systems

    Improved telescope

    •  High Power Rifle Telescope
    •  Easier to align with greater zoom and magnification
    •  Robust shock resistant design

  • •  Fast speed of response provides earliest warning
    •  High sensitivity allows low alarm set points
    •  Alignment free design makes installation simple
    •  Duct flex and vibration tolerance keeps  the system online
    •  Integral functional gas test facility allows for simple system check
    •  Contamination resistant optics reduce the need for unscheduled maintenance
    •  Not affected by interference from water vapor
    •  Immune to catalytic poisons
