Weather Balloon 200 g

We believe in providing our customers with the highest quality products. Our 200 g balloon is no exception. 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. This smaller balloon will reach altitudes that are typically only seen with our competitor's larger 350 g balloons. Characteristics Neck Diameter 3 cm Burst Altitude 21 to 26 km / 70,000 to 85,000 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.
