We are delighted to announce that we have restarted production and service of our cutting-edge Shallow SeaFET™ V2 and Shallow SeapHOx™ V2 pH sensors! After rigorous qualification, testing, and field deployments, we are now accepting requests for quotes and service.
Please submit an RMA Service Request Form. Under the Instrument List, be sure to select “SeaFET V2” or “SeapHOx V2” as appropriate.
If you are located within Canada: Please note that Sea-Bird Scientific recently partnered with TERAMARA (formerly DASCO Equipment Inc.) as an exclusive representative and distributor within Canada. Canadian customers should proceed with service requests through TERAMARA. TERAMARA will complete the RMA Request Form, provide shipping instructions with a preliminary quote, and handle customs clearance. To proceed with return for service, please contact TERAMARA directly at sales@teramara.ca. To ensure that TERAMARA can accurately complete the RMA Request Form, be sure to provide Model Numbers, Serial Numbers, and any other relevant information (e.g., Technical Support Case Number, Deployment Date).
For the most up-to-date lead times, please refer to your RMA Service request or contact your Sea-Bird Scientific sales representative.
The Shallow SeapHOx™ includes (2) separate pH Sensors: an external pH and an internal pH (DuraFET). The DuraFET is protected from salinity changes and therefore exhibits a faster response time in waters with rapidly changing salinity (e.g., estuary, runoff, etc.).
The Deep SeapHOx™ includes only an external pH Sensor, exhibiting a slightly longer response time in waters with rapidly changing salinity. If the deployment region experiences minimal salinity changes and/or changes over longer time scales, then the Deep SeapHOx™ is appropriate for your application.
For a more detailed breakdown of specification differences, please visit our Moored pH Ocean Monitoring Systems page.
What makes the Shallow SeaFET™ V2 and Shallow SeapHOx™ V2 unique is the sensing element, which is an ion-sensitive field effect transistor (ISFET). This class of device has been used for pH sensing in industrial processes, food processing, clinical analysis, and environmental monitoring. The advantages of the ISFET include robustness, stability, and precision that make it suitable for ocean pH measurement at low pressure. The ISFET potential is measured against two separate reference electrodes: one bearing a liquid junction (internal reference) and a solid-state reference electrode (external reference), providing the user with the ability to assess instrument performance and ultimately achieve a greater understanding of the state of acid/base equilibria in seawater.
Service is only available for the Shallow SeaFET V2 and Shallow SeapHOx V2. Service for the Shallow SeaFET V1 and Shallow SeapHOx V1 was discontinued on 01 June 2021 prior to the ongoing service hold. To express our gratitude for your patience and understanding over the past three years, the company is happy to offer a $2,500 USD trade-in discount with the purchase of a new V2. To learn more, please contact your Sea-Bird Scientific sales representative or sales@seabird.com.
If your instrument has a serial number higher than PHS-1051, you have a V2 model. If the serial number is less than PHS-1051, please contact your Sea-Bird Scientific sales representative or sales@seabird.com to confirm.
