What We Do
We now have three types of weather balloons, which can meet requirements of different customers (HY series, RMH series and NSL series).
HY Series Balloon
RMH Series Balloon
NSL Series Balloon
HY series weather balloons use the traditional dipping method. This production technique has been applied by us for more than 40 years, and balloons produced by this method have shown good quality and stable performance.
RMH series weather balloon was a new production technology we developed recent years for customers who had needs for small neck balloons (3cm neck diameter). This type of balloon is suitable for automatic sounding systems; We also have different nozzles that can be adapted to the customer's different filling sets.
The NSL series of weather balloons uses a double-balloon approach, which ensures a higher explosion height. The largest size, the NSL-45, can reach altitudes of 48 to 50 km. If you have any high altitude needs, we welcome your inquiries at any time.
