Digital Barometer PTB330

The Vaisala Digital Barometer PTB330 is designed to capture accurate barometric pressure readings under the harshest of conditions.

Built around Vaisala’s trademarked BAROCAP® sensor technology, the PTB330 combines absolute pressure measurement and exceptional accuracy with low hysteresis and long-term stability.

It’s the perfect digital barometer for tracking the movement of local and regional weather fronts, generating historical models of high- and low-pressure systems, or monitoring developing severe weather for an early warning system. It’s even proven its reliability on Mars.

With the PTB330, you get the current as well as the historical data you need for immediate forecasting and long-term modeling. The system quickly and accurately calculates instant pressure along with WMO pressure trend and tendency code (pressure tendency looking back three hours). It also stores 12 months of barometric data for review.

With a choice of incorporating one, two, or three BAROCAP sensors, the PTB330 barometer offers multiple levels of redundant measurement. When you opt for two or three sensors, the unit constantly compares pressure sensor readings to ensure a stable and reliable pressure reading at all times.
