PTB110-TY digital barometer has better protection and anti-corrosion performance by adopting industrial-grade design and Vaisala core silicon capacitive absolute pressure sensor. This enables a measuring accuracy up to ±0.2hPa. Meanwhile, it supports flexible configuration via RS485 data bus. This product can be widely used in both onshore environmental monitoring scenarios, as well as marine applications such as ships, mobile or fixed oil & gas platforms.
