♦ DO Sensor can be used to measure concentration of O2 in solution. Demarcation is required before using.
♦ Before using the electrode, you have to add filling liquid. Screw off the cover of O2 Sensor electrode. Rinse the electrode cover and metal tube using deionized water. Swing to dry them respectively. Inject filling liquid into cover to fill three quarters of volume of it. Screw back the cover tightly.
♦ Connect sensor to datalogger and computer.
♦ Open SWR iLab to demarcate the sensor (refer to demarcation).
♦ Place the electrode into environment to be measured.
♦ Click ‘Rapid experiment’, ‘Start’ and ‘Stop’ to carry out experiment.
♦ Preserve the electrode carefully to enhance its service life.
♦ Discard the air bubble in electrode cover. Otherwise it will affect the experimental result.
♦ Do not touch the electrode to oil or other organic matter.
♦ DO Sensor is high stable electrode. Do not use sharp object to touch it in case gas-permeable membrane gets broken. During preservation and shipping, you should cover the electrode. Rotate the cover clockwise to take it on or off. Do not drag it violently in case damage the gas-permeable membrane.
