Sea-Bird SBE 18 pH Sensors

The Sea-bird Electronics SBE18 pH sensor can be integrated in the SBE19plus V2 CTD to measure pH to a depth of 1,200 meters. Simple to install, maintain and calibrate, this sensor measures pH to an accuracy of 0.1 pH with a quick time response.

Notable Features

  • 1,200 meter depth rating
  • Fast equilibration times
  • 0-5v signal output

Additional Info

SBE 18 must always be mounted with the pH probe in a vertical orientation, as shown in the spec sheet. A right angle probe configuration is typically required for applications where the CTD is mounted horizontally (for example, in an extension stand below an SBE 32 Carousel Water Sampler) and the SBE 18 is mounted to the CTD.
