Series Advantages
The BAR series digital barometers offer high precision for measuring atmospheric pressure thanks to a 24-bit ADC resolution and temperature compensation. Their compact format allows them to fit into small spaces.
The BAR20 can be used with DracalView or dracal-usb-get in USB mode. If you prefer data integration without third-party software (VCP mode), the BAR20 also allows it.
The BAR20-N, on the other hand, is not compatible with Dracal software tools. It was specifically designed to transmit barometric data in navigation system languages.
