Model No.PS-2195 Introduction Introduction Salinity is an ecological factor of considerable importance, influencing the types of organisms that live in a body of water. Salinity also influences the kinds of plants that can grow in a body of water, or on land fed by the body of water. A quantity of water is considered saline if it contains moderate or relatively high amounts of dissolved salts.
Model No.PS-2195 Setup Setup Hardware Setup The following steps can be performed in any order. 1. Connect the Salinity Sensor Probe to the Salinity Sensor. Connect the Conductivity BNC connector from the probe to the Conductivity input port on the sensor. Push the BNC connector onto the port and turn the connector clockwise (left-to-right) until the connector locks into place on the port. 2. Connect the Temperature input plug from the probe to the Temperature input port on the sensor. 3.
Salinity Sensor Setup SPARK Setup • If the SPARK Science Learning System (SLS) is off, press and hold the power button on the bottom to turn it on and then wait for the SPARK to boot up. The screen will show a message to plug in a sensor. • Connect the PASPORT sensor to either of the ports on the top of the SPARK. The screen will show the list of quantities measured by the connected sensor.
Model No.PS-2195 Specifications More About Calibration You can also calibrate the Salinity Sensor using a standard salinity solution purchased from a company such as Hach (www.hach.com) or Lamotte (www.lamotte.com) that offers water quality testing equipment. A third way is to make a calibration solution from “Instant Ocean® Sea Salt” (www.instantocean.com) which can be purchased at most aquarium supply stores.
Salinity Sensor T e c h n ic a l S u p p o r t Storage The Salinity Sensor Probe can be stored dry. Rinse the tip with distilled water and then dry it using a soft, nonabrasive towel.

Salinity Sensor Experiment: Temperature Dependence of Conductivity in Dilute Aqueous 3. Connect the Salinity Sensor to the data acquisition interface. Support the Salinity Sensor Probe with a clamp that is mounted on a base and support rod (see Figure 1). Place the hot plate with magnetic stirrer below the tip of the probe. 4. Start the data acquisition program. Set up a graph display that shows conductivity Calibration is not needed for this experiment.
Model No.PS-2195 Notes on the Experiment Notes on the Experiment If bubbles form inside the probe, the conductivity reading will be reduced because the bubbles will form an insulating later on one or both of the electrodes. One way to eliminate the bubbles is to tap the probe. Another way is to increase the speed of the magnetic stirrer to allow more solution to flow through the probe. If time is limited, prepare the solutions before the period begins. Data Table Solution percent change/ °C at 25 °C 0.
