1. Ignition delay times and complete combustion of the sample (τd, τb).
2. Gas temperature (Tg). 
3. Anthropogenic emissions (O2 (0–25%, ±0.2%), SO2 (0–1000 ppm, ±5%), NO (0–2000 ppm, ±5%), NO2 (0–500 ppm, ±7 %), H2S (0–500 ppm, ±5%); CO2 (0–30%, ±2%), CH4 (0–50%, ±5%), CO (0–50%, ±5%) , H2 (0–30%, ±5%)) 
4. Radius of a gas hydrate particle (Rd) and its speed of movement (Ud)
   
   The systematic error in measuring particle sizes, their movement speeds and ignition delay time was 2.1%, 3.4% and 2.8%, respectively.
