Building on 80 years of experience, Vaisala provides observations for a better world. Vaisala is a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.

Vaisala PTB110 Barometer is made for precise barometric pressure readings at room temperature and for monitoring environmental pressure across various temperatures. Its small size makes it perfect for environmental monitoring, data buoys, laser interferometers, and in agriculture and hydrology. Due to its very low power consumption, the barometer is particularly ideal for different data logger applications. Vaisala PTB110 uses the Vaisala BAROCAP sensor, a silicon capacitive absolute pressure sensor developed by Vaisala for barometric pressure measurement applications. The sensor combines the outstanding elasticity characteristics and mechanical stability of single-crystal silicon with the proven capacitive detection principle.
