For a project at CU Boulder, my team must create a weight and cost budget for our balloon satellite. We have to send a balloon satellite up to the stratosphere and it cannot weigh more than 800 grams. Does anyone know the precise mass of the adafruit Geiger counter? If anyone knows, that would be super beneficial.

with batteries: 138g
without batteries: 116g

both include the case and tube. Removing the case will save about 60g.

Vacuum General was acquired by Tylan Tylan General, which was later acquired by Mykrolis. You might find info under the other company names. Which MFC do you need data for?
