    Salinity and pressure impacts on sensor response are each checked at two separate points. The SBE 63 is designed for use in a CTD's pumped flow path. Water does not freely flow through the plumbing between samples, allowing anti-foul concentration inside the system to maintain saturation and eliminating exposure of the sensor to light, maximizing bio-fouling protection.

    Polled Sampling • SBE 63 response to commands is not shown in examples. On command (TS or TSR), the SBE 63 takes one sample of data and transmits the data. Example 1: Polled Sampling (user input in bold). Set up to wait for a command upon power up (SetAutoRun=0). Set up to echo commands (SetEcho=1), output converted oxygen and temperature data (SetFormat=0), and average 2 measurements/sample (SetAvg=2).

Some common commercial product names are Clorox (U.S.) and eau de Javel (French).Clean the SBE 63 with a 500 - 1000 ppm solution of water and sodium hypochlorite. Dilute the concentrated household bleach to 50 to 1 (50 parts water to 1 part bleach) to produce the proper concentration to clean the oxygen sensor.

    Another important mechanism for oxygen sensor drift is photobleaching of the sensor film. Keep the SBE 63 sensor film out of direct sunlight. Also, every sample that is taken illuminates the film with short wavelength light that eventually degrades the film.
