Ideal for space-constrained applications, this USB barometer provides high-resolution readings for atmospheric pressure (1 to 120 kPa) and altitude. Moreover, this calibratable barometer communicates with the instrument in virtual COM port mode and uses a 24-bit analog-to-digital to detect low variations in air pressure.

The BAR20 is a digital barometer operating within a range of 1 to 120 kPa with high precision. Its unique USB key-like design allows seamless integration into various systems.
Like all Dracal measuring instruments, the TMC200 is compatible with free software tools, making it an essential component of a DAQ solution. For those looking to integrate the TMC200 into their system, two options are available: command-line tools and VCP mode. If you prefer a graphical interface, DracalView is the appropriate choice.
