This model was modified for installation on Slocum gliders. The unit is designed to provide stable salinity data accurate to 0.005 PSU for periods in excess of three years without any form of maintenance. Temperature is within 0.002 C (stability 0.0002 C/year) and pressure within 2 dbar (stability 0.8 dbar/year).",

The SLC designation signifies this is a third generation model that is specific for integration into Slocum gliders with a dry science bay. The fluorometers and scattering meter are single wavelength sensors. The model is fitted with an added copper faceplate for bio-fouling mitigation and is depth-rated to 1000 m.",

            "description": "A dissolved oxygen sensor which provides analogue (0-5V) and digital output (RS-232) to third party data loggers, gliders and floats. Measurement based on the ability of selected substances to act as dynamic fluorescence quenchers. The fluorescent indicator is a special platinum porphyrin complex embedded in a gas permeable foil that is exposed to the surrounding water. In this standard model, a black optical isolation coating protects the complex from sunlight and fluorescent particles in the water. This sensing foil is attached to a window providing optical access for the measuring system from inside a watertight housing. The foil is excited by modulated blue light, and the phase of a returned red light is measured. For improved stability the 4831 optode also performs a reference phase reading by use of a red LED that does not produce fluorescence in the foil. This model is fitted with a standard sensing foil. By linearizing and temperature compensating, with an incorporated temperature sensor, the absolute O2 concentration can be determined. Accuracy +/- 1.5% or 2uM; precision +/- 0.2 uM.",
