MODEL SOLU COMP II	SECTION 1.0
	DESCRIPTION AND SPECIFICATIONS

DISSOLVED OXYGEN (Code -25)

When used with an oxygen permeable membrane- covered amperometric sensor, display choices are ppb or ppm dissolved oxygen or % saturation.

Because the permeability of the membrane is a func- tion of temperature, a correction is necessary when the sensor is used at a temperature different from the one at which it was calibrated. The Solu Comp II automatically applies the temperature correction fac- tor. The process temperature is measured by an RTD in the sensor. Calibrating the analyzer is as simple as exposing the sensor to air and keying in the baromet- ric pressure. If removing the sensor from the process is impractical, the analyzer can also be calibrated against a standard instrument. Solubility correction factors for liquids containing high concentrations of electrolytes can be registered into the analyzer. The Solu Comp II automatically calculates ppb/ppm dis- solved oxygen taking into account the high salt con- centration.

DISSOLVED OZONE (Code -26)

For use with an ozone permeable membrane-covered amperometric sensor. Because the permeability of the membrane is a function of temperature, a correction is necessary when the sensor is used at a temperature different from the one at which it was calibrated. The Solu Comp II automatically applies the temperature correction factor. The process temperature is meas- ured by an RTD in the sensor. The Solu Comp II is calibrated taking a measurement of the ozone level in the process by an independent chemical method and setting the display equal to the measured value. An input filter allows the user to configure the analyzer for rapid response of low noise. The low noise option is recommended for samples containing less than 0.1 ppm dissolved ozone.
