Depending on your site needs, INW’s PT12-BV barometric pressure sensor comes as either a weatherproof box or stainless steel tube. Both versions provide an ideal barometric reference for absolute pressure sensors.
As a weatherproof box, it also offers automatic barometric compensation when used with SDI-12. Simply attach the PT12-BV to a PT12 submersible sensor and receive barometrically compensated pressure readings. No post-processing of data. No vented cable. No desiccant tubes.

Featuring both an SDI12 (v.1.3) interface and a Modbus® RTU interface, the PT12-BV is easy to connect to recorders and existing monitoring networks, making it the preferred choice for many environmental professionals.
