The Barometer is intended for measuring atmospheric pressure within the range from 300 to 1100 hPa (mbar). The sensor is located inside the device case. Many chartplotters and digital navigation instruments are able to display data on pressure in the form of graphs or show a trend indicator; this allows tracking of trends in the weather change. The Device dimensions, including the connector, are 54x20x20mm, the mass is only 11 grams, so it is suitable for racing yachts. Pressure data output resolution 0.01 hPa (mbar),absolute measurement accuracy is ±1 hPa, relative measurement accuracy is ±0.12 hPa.
