Weather Balloon 1500 g


Our 1500 g weather balloon is a workhorse that will transport your payload higher than any other 1500 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 1500 g balloon’s performance, we will send you another 1500 g weather balloon at no additional cost!

Cheap 1500 g balloons have short, fat necks that are challenging to tie off. Our 1500 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.


Neck Diameter 3 cm
Burst Altitude 35 to 40 km / 115,000 to 130,000 ft
