Y511-A Turbidity Sensor Calibration
Required equipments and raw materials
required equipments: three 1L brown bottles, one magnetic stirrer, one iron stand, two magnetic rotors, one set of gloves.
raw materials: 460NTU turbidity standard solution, distilled water or deionized water.
Calibration steps
There
are three methods of user calibration for the turbidity sensor: 0-point calibration, 1-point calibration and 2-points
calibration.
0-point calibration was done in deionized water, 1-point calibration was done in 460 NTU standard solution, 2-points calibration was done in deionized water and 460 NTU standard solution.
0-point calibration step (change the B value)
Put
an appropriate amount of distilled water or deionized water into a 1L
brown bottle, put the sensor in the center of the brown bottle, which
not close to the wall around the brown bottle, and then fix the sensor
with an iron stand, adjust the high and low position of the sensor. Pay
attention to maintain a distance greater than 10cm between the front end
of the sensor and the bottom of the brown bottle.
Under the “Automatic Calibration” interface, click “0 point” to do zero-point calibration, wait for the values in the pop-up window to stabilize, and click “OK” to complete the calibration. Click “Get” to check whether the B value is written correctly.
Click “Start” under the “TUR” interface to get the real-time measurement of the turbidity and temperature, check that the turbidity is close to 0NTU to verify that the zero-point calibration is successful.
1-point calibration step (change the K value)
Put
an appropriate amount of 460NTU turbidity standard solution into a 1L
brown bottle, put in a magnetic rotor, place the brown bottle on the
magnetic stirrer, and open the magnetic stirrer to stir the standard
solution thoroughly. Put the sensor in the center of the brown bottle,
which not close to the wall around the brown bottle, and then fix the
sensor with an iron stand, adjust the high and low position of the
sensor. Pay attention to maintain a distance greater than 10cm between
the front end of the sensor and the bottom of the brown bottle.
Under the “Automatic
Calibration” interface, change the “Single/First Point Calibration
Value” to 460, click “1 point” to do one-point calibration, wait for the
values in the pop-up window to stabilize, and click “OK” to complete
the calibration. Click “Get” to check whether the K value is written
correctly.
Click “Start” under the “TUR” interface to get the
real-time measurement of the turbidity and temperature, check that the
turbidity is close to 460NTU to verify that the one-point calibration is
successful.
2-points calibration step (change the K and B values)
Drop
down “Port” and select the corresponding COM port, and then click
“Connect”, after connecting the sensor successfully, click “Measure”.
Under the “TUR” interface, click “Brush”, and click “Turn On Brush”
under the “Wiper” interface to remove the bubbles on the test window.
Click “Start” to get the real-time measurement of the turbidity and
temperature.
Under the “Automatic
Calibration” interface, change the “Single/First Point Calibration
Value” to 0, change the “Second Point Calibration Value” to 460, click
“2 points” to do two-points calibration, wait for the values in the
pop-up window to stabilize, and click “OK”. Then clean the sensor with
distilled water or deionized water, wipe it dry and put it into the
460NTU turbidity standard solution after full stirring according to the
method of step 2, wait for the values in the pop-up window to stabilize,
and click “OK” to complete the calibration. Click “Get” to check
whether the K and B values are written correctly.
Click “Start” under
the “TUR” interface to get the real-time measurement of the turbidity
and temperature, check that the turbidity is close to 460NTU, then clean
the sensor with distilled water or deionized water, wipe it dry and put
it into the 0NTU turbidity standard solution after full stirring
according to the method of step 2 to get the real-time measurement of
the turbidity and temperature, check that the turbidity is close to 0NTU
to verify that the two-points calibration is successful.
