The Vaisala PTB330 barometer is designed for a wide range of high-end atmospheric pressure measurements. Built around Vaisala's BAROCAP® silicon capacitive, absolute pressure sensor, the PTB330 provides high measurement accuracy and excellent long-term stability making it the ideal tool for applications in which quality counts such as aviation, professional meteorology, and for demanding industrial pressure measurement applications.
The PTB330 series is available in two accuracy ranges. The Class A barometers have an accuracy of ±0.10 hPa for the most demanding applications and are fine-tuned and calibrated against a high-precision pressure calibrator. Class B barometers have a ±0.20 hPa accuracy and are adjusted and calibrated using electronic working standard. All the PTB330 barometers come with a NIST traceable, factory calibration certificate.
The PTB330 can be set to compensate for QNH and QFE pressure commonly used in aviation. The QNH represents the pressure reduced to sea level, based on the altitude and temperature of the observation site. The QFE represents the height corrected pressure of small differences in altitude, for example, the air pressure at the airfield elevation.
The PTB330 features a multi-lingual, graphical display allowing users to monitor measurement trends. The graph is updated automatically while measuring and it provides a one-year measurement history. In addition to instant pressure, the PTB330 also provides the WMO pressure trend and tendency codes.
