The method of utilizing lasers to measure the absorption of radiation, as a function of wavelength, has been harnessed by small unmanned aerial systems (sUAS) through the use of Tunable Diode Laser Absorption Spectroscopy (TDLAS).
Rhino Environmental’s sUAS TDLAS payload abilities include methane (CH4) detection at 0-50,000 parts per million (PPM). Sampling rate response time of 25 milliseconds allows for accurate aerial methane detection. Samples can be taken at altitude up to 300′ above ground level (AGL) providing an interference free sampling experience.
Relevant practical applications include: gas pipeline leak detection in difficult to access or hazardous locations, landfill gas detection including oder study and leak detection without disturbing active area workflow. Reduce risk exposure from surface sampling by using sUAS aerial inspection services. Contact Rhino Environmental today for more information regarding sUAS TDLAS methane gas detection.
Rhino Environmental’s sUAS fleet offers additional gas detection payload capabilities including:
- 300 mL/min active pump multi-gas photoionization detector (PID)
- Lower Explosive Limit (LEL) detector
- Sensor detector for:
- Oxygen (O2)
- Chlorine (CL2)
- Nitrogen Dioxide (NO2)
- Hydrogen Sulfide (H2S)
- Carbon Monoxide (CO)
- Sulfur Dioxide (SO2)
sUAS TDLAS does not meet EPA Method 21 requirements for landfill quarterly Surface Emissions Monitoring (SEM).
