Weather Balloon 1200 g

Our 1200 g weather balloon is a workhorse that will transport your payload higher than any other 1200 g balloon. Although it is more expensive than the Chinese and Indian weather balloons, its quality is far superior. This enables you to achieve higher altitudes with a smaller weather balloon, less helium, and less overall cost. If you are not satisfied with your 1200 g balloon’s performance, we will send you another 1200 g weather balloon at no additional cost! Cheap 1200 g balloons have short, fat necks that are challenging to tie off. Our 1200 g weather balloon features a 14 cm long neck with a 3 cm diameter. This makes it a lot easier for your ground crew to tie off the neck after inflating the balloon. Characteristics Neck Diameter 3 cm Burst Altitude 34 to 37 km / 110,000 to 120,000 ft   Balloon Performance To calculate the optimal amount of helium you need for your balloon and the maximum altitude possible for a given payload mass, see our Balloon Performance Tutorial.
