Aerotracer is a portable analyzer capable of identifying substances such as engine oils, hydraulic liquids, heat transfer fluids, glues, de-icer compounds, kerosene and more to help maintenance staff quickly identify the type of compound and source in order to resolve an odor related maintenance incident expediently. Traditional methods employ extensive run-up procedures trying to confirm the source of the smell and are often supported by boroscopy of the suspected sources. This "trial and error" method historically involves long search times delaying an aircraft return to service time and costing an airline significantly more money.
