| Part # | Description | Notes |
| 18 | pH SENSOR - Modular sensor for use in profiling mode only, 1200 m depth capability, output 0-5 V. Includes complete documentation. |
 Replaceable
pH probe is permanently sealed & is supplied with soaker bottle attachment
that prevents reference electrode from drying out during storage. Soaker
solution is pH 4 buffer solution saturated with KCL.SBE 18 can be ordered in two ways:
Sea-Bird does not recommend use of pH sensor for moored applications; see Application Note 76: pH or pH/ORP Sensors and Moored Applications. |

SBE 18 Probe Configuration Option |
||
| 18-1 | Right angle probe configuration (for horizontal mounting) |
 SBE
18 must always be mounted with pH probe in a vertical orientation, as
shown at right.
Right angle probe configuration is typically required for applications
where CTD is mounted horizontally (for example, in extension stand
below SBE 32 Carousel Water Sampler) and SBE 18 is mounted to CTD. |
| SBE 18 Wet-Pluggable Connector Option | ||
| 18-2 | Substitute Wet-pluggable (MCBH) connector for Standard (XSG) connector |
 Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on the connector pins is forced out as the connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to our standard (Impulse XSG/RMG) connectors. Like standard connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets. |
| SBE 18 Accessories | ||
| 30459 | Plastic soaker bottle for pH probe | Soaker bottle filled with soaker solution comes standard with SBE 18; this is spare. |
| 50020 | pH sensor O-ring kit |
Spares kit includes 1 each of:
|
| 24023 | pH electrode | Electrode & electrode guard come standard with SBE 18; these are spares. |
| 23190C | pH electrode guard | |
| 25001 | KCl soaker solution, 500 ml bottle | Soaker solution is pH 4 buffer solution saturated with KCL. When SBE 18 is not in use, place plastic soaker bottle over pH electrode to prevent loss of internal electrolyte & resulting change in sensor performance. Soaker bottle filled with soaker solution comes standard with SBE 18; this is spare solution. |
