Contact Us Digital Barometer PTB330 for professional meteorology, aviation, and industrial users This PTB330 barometer - designed for a wide range of high-end atmospheric pressure measurement - is based on the Vaisala BAROCAP® Sensor. It is a Vaisala in-house, silicon capacitive, absolute pressure sensor providing high measurement accuracy and excellent long-term stability. Features Vaisala BAROCAP® sensor Accurate measurement Excellent long-term stability Added reliability through redundancy Graphical trend display with 1-year history data Altitude corrected pressure (QFE, QNH) + Show more Key Benefits Excellent long-term stability through technology The PTB330 offers high measurement accuracy and superior stability thanks to the Vaisala BAROCAP® Sensor. These barometers operate over a wide temperature range and perform reliably even in highly demanding applications such as professional meteorology and aviation. Low hysteresis, high repeatability Combining two powerful technologies – single-crystal silicon material and capacitive measurement – BAROCAP® sensors feature low hysteresis and high repeatability. Reliability through redundancy When two or three sensors are used, the barometer continuously compares the readings of the pressure sensors against one another and provides information on whether these are within the set internal difference criteria.
