Future of Sensory Technology
Scentroid DR300 Sampling drone adds a new dimension to air sampling. The DR300 Sampling drone can be used to sample ambient air at heights of up to 125 meters above ground level or directly sample from stack plumes. Height sampling and direct plume sampling opens a new avenue that can be used to increase accuracy of emission and impact assessment.
With the DR300 sampling drone operator can stay safely away from hazardous sources while acquiring environmental samples.
The DR300 can be flown into the plume of a flare to take direct samples for analysis for chemical composition and olfactometery. Temperature and humidity of the plume are also measure to ease dispersion calculation.
Scentroid DR300 air sampling drone Is capable of providing remote monitoring of more than 50 chemicals. Data from on-board sensors are transmitted to operator’s tablet for to be viewed live and logged.
Refineries, petrochemical plants, and many other processes have emissions that are difficult to sample using traditional methods. The sampling drone opens a whole new dimension in air sampling by allowing the operator to take direct samples from odour plumes and other sources that are difficult and /or dangerous without exposure to physical or chemical hazards.
Taking samples at various heights upwind and downwind of the plant allows for accurate measurement of all emissions generated by the plant without the need for source sampling.
The Scentroid DR300 sampling drone is a complete package where one person can fly the drone, monitor the exact location of the drone including longitude, latitude, altitude, height and take samples all without being exposed to any physical or chemical hazards. The dedicated remote and Drone App allow the operator to initiate pump, monitor H2S and Ammonia, take temperature, GPS position and height readings.
The Scentroid DR300 sampling drone comes as a complete sampling solution. The kit includes the drone, remote controller with the device holder, standing legs, sampling probe, 3 custom made sampling bags, set of spare rotor blades, battery charger, spare battery pack, safety string rolls, etc.
Scentroid DR300 Air sampling drone provides continuous monitoring of multiple chemicals. While in flight, built-in sensors can provide remote monitoring of H2S, Ammonia, VOC, and more than 30 other chemicals. Data is transmitted to the operator’s tablet for live monitoring and recording. Chemical readings along with GPS position and altitude can provide 3D mapping of ambient pollution and odour levels. This feature can also be used to guide the operator into a plume for bag sampling.

The Sampling drone can be operated in temperature up to 70C. At 60C the drone program will warn the operator to take necessary actions.
Yes. Chemical sensors are installed for measurement and also for aiding the operator to position the drone in the plume. Standard sensor is H2S.
The standard sample bag that is included is 3 Liters but larger ones up to 10 Liters can be ordered.
Yes. Under 100 mbar the standard unit will operate with minimal dilution variance. Above 100 mbar specific calibration sheets are provided by Scentroid and should be used.
This is brilliant. Previously we used man hot air balloons for height samples which were very dangerous. The drone makes it very simple to take height samples and keeps our feet on the ground.
