Hwoyee meteorological balloon is made from 100% natural rubber latex compound with several additives which can highly improve its resistance to high-low temperature, oxidation, and ozone. We now have two different types of meteorological balloons (HY type and RMH type); the main difference is on neck diameter which can meet the needs of different customers (our RMH balloon’s neck diameter is 3cm). Hwoyee meteorological balloon includes a pilot balloon, ceiling balloon, and sounding balloon with sizes from 10g to 6000g. For detailed product information, please see our specification list as below:

  Global Climate Observing System (GCOS)：In 2005, we started to research and develop 1600g meteorological balloon specialized for Global Climate Observing System (GCOS). Through several years’ efforts, we’ve made great achievements on this project. Until now, according to results received from GCOS stations (our 1600g sounding balloon have been used in 7 GCOS stations and 1 non-GCOS station in China), the percentage of 1600g balloon with average bursting altitude reaching to 38000m accounts for 50%, 36000m is above 80% and ＞30000m is 100%.
