Oakton Multiprobe Use
All measurements need to occur in flowing water. Make sure that you do not damage the sensors by placing them against the substrate on a lake or stream. The probes are waterproof and float, but be sure to use the lanyard so they do not get lost.
Steps for using Field Probe

Press "ON/OFF" to turn on meter and select "MODE ENT" to select the first parameter that you want to measure. Remove the cap and store in a safe location. |
||
Hold the tip of the probe completely submerged underwater, but leave the screen visible. Wait one to two minutes while the value adjusts. Once the value has settled record the number on your data sheet. You can press the "HOLD" button to lock in the current value if you need to remove
the sensor from the water to write on the datasheet.

Pay special attention to the units. The conductivity, TDS, and salinity can change based on the hardness of the water. If they do you will need to convert your data before you record it on the database.

After you have measured all parameters rinse the sensors off with clean water. |
