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:
