Meteorological balloons
InterMet offers a range of meteorological balloons, tailored to the user’s requirements for payload and altitude performance.
-
- Natural Latex rubber
- Reinforced inflation neck
- Reliable burst altitude performance
-
The mass of the balloon determines how much inflation gas (Hydrogen or Helium) the balloon can hold. To carry a large payload, more gas must be used to achieve the desired buoyancy; however, the balloon will burst at a lower altitude. Alternatively, less gas could be used; however, the assent rate will be lower which results in a longer flight. The meteorological standard for assent rate is 5m/s.
