The B1100-2 uses a high precision digital sensor that makes the B1100-2 suitable for altitude measurements, vertical velocity indication, and weather monitoring. Data is recorded at a user selectable rate ranging between 20 Hz to one sample per hour. The B1100-2 can be programmed to start and stop at specific times each day. When connected via the USB to a personal computer, the B1100-2 appears as a standard mass storage device containing the comma delimited data files and user setup files. The commercial standard "AA" battery provides extended life operation suitable to long term data acquisition applications.Buy On Amazon
