Make

Sea-Bird Electronics

Model

Deep SeapHOx (350 m)

For more information about this instrument, including its available Data Products, please see the Seawater pH (PHSEN) Instrument Class page.

Starting in 2025, certain PHSEN-A/D instruments (Sunburst SAMI-pH) have been replaced by PHSEN-G/H series (Sea-Bird Deep SeapHOx) instruments. The Deep SeapHOx V2 sensor uses ion-sensitive field effect transistor (ISFET) technology to measure pH in marine environments at depths up to 2000 meters.
