    The two sensors are integrated by the manufacturer. The SeaFET V2 acts as a controller for the SBE-37, which sends the data it collects to the SeaFET V2. Because the SBE-37 pump operates before each burst of data collection, the manufacturer recommends that the shortest data collection interval is every two minutes for the SeapHOx.

  • Page 14: Ion-Sensitive Field Effect Transistor (Isfet)

    Product overview 3.1 Ion-sensitive field effect transistor (ISFET) ™ The primary sensor element of the SeaFET is the ISFET, a solid-state sensor that senses pH in marine environments. The ISFET has two reference electrodes: an internal reference and an external reference, that give separate reference potentials to the ISFET and show separate pH values (pH Internal and pH External).
  • Page 15 The main battery pack supplies power to the sensor and the isolated battery pack supplies power to the sensing element when the sensor is in a low power "standby" mode. SeapHOx: SBE-37-SMP-ODO integrated with SeaFET V2 SBE-37-SMP-ODO batteries The SBE-37-SMP-ODO attached to the SeaFET uses lithium batteries that ship separately and must be installed before use if the SeaFET is not set up to supply power to the SBE-37-SMP-ODO.

  • Page 22: Deployment Orientation

    Deployment and recovery The standalone SeaFET operates continuously user-selected intervals from 6 to 21600 seconds. Data is transmitted in engineering units. 5.1 Deployment orientation When deployed as a stand-alone sensor, the orientation of the SeaFET should be based on the deployment site conditions. Light exposure to the ISFET could cause errors in the data, so in high-sun areas, it is best to deploy the sensor with the wet cap pointed down.
