Weather balloons, also known as sounding or meteorological balloons, are used in a variety of capacities by the scientific community to gain valuable information about the atmosphere. Weather balloons are a vital part of daily weather forecasting, storm prediction and upper atmosphere wind measurement. Read More Here (leaving kaymont.com)

Kaymont balloons have been trusted by the National Weather Service, NASA, all branches of the US Military, educators and enthusiasts for over 30 years.

To determine the right balloon for your flight goals, you'll need to know your payload weight, target altitude and lifting gas of choice. Balloons should be launched with a target ascent rate of 5m/s for optimal performance. For a general idea of balloon altitude capabilities, use the habhub calculator below, inputting your payload weight and setting your ascent rate to 5m/s. Leave the target altitude blank and flip through our balloons in the drop-down menu. Use the Burst Calculator Here (leaving kaymont.com)

No.

Kaymont weather balloons are launched daily by the National Weather Service with a radiosonde payload. The radiosonde can be collected and recycled. All NWS radiosondes include return shipping instructions. Read More Here (leaving kaymont.com)

Could be either. Weather balloons in flight can travel at great speeds due to high winds at altitude, and their payloads may be reflective or have lights on them. Weather balloons can "disappear" and "reappear" behind clouds that are tough to see from the ground. Weather balloons can appear spherical, or slightly oblong due to their rate of lift. Weather balloons, when properly inflated and launched, will rise at a steady rate to their burst altitude, and their payloads will return to the ground via parachute. You cannot be abducted by a weather balloon. Read More Here (leaving kaymont.com)

A humidity generator is a highly accurate and stable scientific instrument which creates a testing environment with an adjustable temperature and relative humidity. These instruments are used to calibrate humidity probes, chart recorders and data loggers. Kaymont and GEO Calibration Humidity Generators are portable, lightweight, extremely reliable and affordable.
