The pH sensor will be shipped dry but was pre-conditioned in seawater (generally from Pacific Ocean waters near Hawaii). While conditioning and evaluating the pH sensor, only expose it filtered, sterilized natural seawater. Do not use seawater CRMs (Certified...

Can I collect vertical profile data with my SeaFET V2, SeapHOx V2, or Deep SeapHOx V2 pH sensor?
The SeaFET and SeapHOx systems are designed to sample at a fixed depth. If you want to run discreet samples at depth intervals, you will need to find a way to move the system to a specific depth before each sample interval and stop the descent / ascent for the entire...
My Deep SUNA V2 has the optional APF relay feature. What voltage level is recommended to activate the relay? When should I apply power to the relay, and for how long?
The nominal control voltage for the relay is 12 VDC. However, between 5 - 30 VDC will work, applied to pin 4 relative to the ground pin 2 on the Deep SUNA V2. The voltage can be applied to the relay any time after external power is applied to the instrument for a...
My SUNA nitrate sensor is not transmitting or storing valid nitrate concentration data in high sediment, high turbidity, low light transmission environments, or freshwater inrush events. What can I do to mitigate this?
SUNAs ordered with the 5mm path length coupler as a factory option will perform much better in low light transmission waters due to the shorter length the light needs to travel leading to less absorption. Equipping your SUNA with the factory bio-wiper option will also...
How can I determine if an SBE9 or SBE9plus CTD is compatible with a specific SBE11 or SBE11plus deck box?
There are several considerations when determining whether the deck box and CTD underwater unit will be compatible. (1) In most cases (with the exception being (2), below), instruments with the "-plus" designation are compatible with each other, but the "-plus"...
I am ordering a CTD and want to use auxiliary sensors. Should I order them from Sea-Bird also, or deal directly with the sensors’ manufacturers?
This depends on your own expertise and resources. We have extensive experience in integrating and supporting a wide range of auxiliary sensors, but not everything under the sun. We have a large list of commonly used sensors that we routinely offer for sale...
How should I pick the pressure sensor range for my CTD? Would the highest range give me the most flexibility in using the CTD?
While the highest range does give you the most flexibility in using the CTD, it is at the expense of accuracy and resolution. It is advantageous to use the lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy and...
I want to integrate a moored CTD with some auxiliary sensors (transmissometer, fluorometer, etc.). Which CTD should I use?
Sea-Bird currently manufactures only 1 moored CTD that can accept auxiliary sensors, the SBE 16plus V2 SeaCAT (and its inductive modem version, the 16plus-IM V2). These instruments measure conductivity and temperature; a pressure sensor is...
Which Sea-Bird profiling CTD is best for my application?
Sea-Bird makes four main profiling CTD instruments, as well as several profiling CTD instruments for specialized applications.In order of decreasing cost, the four main profiling CTD instruments are the SBE 911plus CTD, SBE 25plus Sealogger CTD, SBE...
