"This drone-based sniffing solution allows us to quickly identify the suspected ships that use unqualified fuel. It helps reduce the risk of personnel contact on-boarding during the epidemic, extend inspection coverage, and expand inspection targets from arriving ships to transiting ships for emission control. It also brings effective warning and deterrent on the ships using unqualified fuel."

"The UAV-based Sniffer4D monitoring system is an excellent product that can achieve fast and accurate air pollutant measurement in real-time. We have been using Sniffer4D for the observations of atmospheric anthropogenic and biogenic emissions. Sniffer4D not only provides relatively reliable measurements with high sensitivity, but also offers a greater data spatial resolution when compared to traditional methods. Its high portability and cost-effectiveness open up new possibilities for atmospheric chemistry and physics research such as studies on pollution vertical distribution and atmospheric stratification."

Lee Newman,

Station Officer at London Fire Brigade

"Sniffer4D is really good and performed well during the trial... the gas detection system was able to provide more details about the smoke cloud than a visual camera could, telling us what type of hazardous substances were in the plume, their concentration, and where they were heading... this would not only help us tackle the incident, but help us better protect the nearby community, taking preventative action such as telling them to shut windows or redirect traffic - especially if there were high levels of really dangerous substances. And the system obtains the information you need while keeping crews away from the incident."

"The solution of drone-mounted Sniffe4D and the infrared thermal camera proved its value in monitoring air pollution for both control areas and high-concentration areas including construction sites, roads and industrial enterprises. It accurately obtains and processes the concentration information with ultra-high spatial resolution, helping us determine the pollution level and its vertical distribution, locate the sources and analyze the causes with efficiency. In this case, we can vigorously improve our ability to precise environmental supervision. "

"The moment when the multi-gas sensing and mapping system Sniffer4D was formally equipped for the front-line law enforcement team, our local environmental law enforcement has entered a new stage of modernization."
