Up 30gm Balloon

10 gram Meteorological Balloon Neck Size Comparison

As a result of the cessation of balloon production by Kaysam Worldwide Inc.  Many United States users will be switching to meteorological balloons made by Totex of Japan. 

The quality of the Totex balloon is very high due to the more modern methods of forming the balloons employed by Totex.  The neck sizes of the Totex 10 gram pilot balloon is similar to the commonly shipped Kaysam 10 gram balloon.

Samples of 10 gram Kaysam balloons purchased in June of 2003 were compared to samples of 10 gram Totex balloons obtained from Kaymont  a US distributor for Totex.  

The balloon necks were flattened and the with measured with a caliper.   The sample balloons were then fitted to a standard   U.S. Specification 10 gram Pilot Balloon Nozzle.
