The PT12-BV is a stand-alone digital barometric pressure sensor, manufactured by Seametrics, the PT12-BV measures barometric pressure, temperature and voltage.

The weatherproof version is ideal for barometric reference when used with absolute pressure sensors. This version features both an SDI-12 and a Modbus® RTU interface, These powerful features enhance the sensor’s capabilities to achieve connectivity with data recorders making it a preferred choice by environmental professionals with existing SDI-12 or Modbus® RTU systems.

Additionally, this sensor can be paired with a submersible pressure transducer model PT12. When this configuration is used, the PT12-BV provides automatic barometric pressure compensation, eliminating additional steps in your data management process.
