Nasal Ranger®

The Nasal Ranger® is a portable, innovative odour measuring device (Olfactometer) that allows users to quantify odour concentration in terms of ‘Dilution-to-Threshold’ (D/T) ratio. The Nasal Ranger® is used to measure odour strength at specific locations surrounding a facility and negates the need for laboratory analysis. Now, facility operators, regulators and local residents can conduct odour monitoring and documentation in the field. The Nasal Ranger® goes beyond traditional estimation methods, easily measuring odour strength at specific locations surrounding / within a facility. With the Nasal Ranger® you can:

  • Monitor daily operations
  • Evaluate odour mitigation methods
  • Create credible, defensive evidence
  • Investigate odour control effectiveness
  • Determine specific odour sources
  • Verify odour complaints
