•To prevent the errors from ambient light interference, do not use the meter in direct sunlight. Always close the light shield
lid during the. measurement and calibration.
•The vial and cap must be cleaned thoroughly with deionised water after each measurement. Any residues can cause
inaccurate readings.
Turbidity Calibration
•The METRIA M10 portable turbidity meter is calibrated with Formazin Standards at the factory and does not require user
calibration prior to use.
•Do not shake or agitate the calibration standard violently to prevent air bubbles.
•In order to get accurate measuring results, we recommend calibrating the meter at least once a month.
•The meter allows turbidity calibration up to 5 points with minimum of 2 points, the default calibration points include the
0.02, 10.00, 200, 500 and 1000 NTU. For better accuracy, ensure that selecting a calibration point close to the sample value you
are measuring.

Measurement
An accurate turbidity measurement depends on good measurement techniques. Factors such as clean sample vials, positioning
of vial in the
Arrow

measurement chamber, covering the vial with the light shield lid, meter calibration, removal of bubbles, etc. For more information,
please refer to page 7 “Measurement and Calibration Hints”.
Single measurement - low turbidity samples (< 200 NTU)
For the low turbidity samples, we recommend using the same vial to perform the measurement and calibration.
1.1. Rinse the vial with approximately 10ml of the sample, capping the vial with the screw cap and gently inverting it several
times. Discard the used sample and repeat the rinsing procedure two more times.
1.2. Fill the vial with the sample. Cap the vial.
1.3 Wipe the vial with the lint-free cloth to remove waterdrops and fingerprints. Ensure that the outside of vial is dry and clean.
1.4 Place the vial in the measurement chamber. Align the mark on the vial with the arrow on the meter.
1.5 Close the light shield lid. Press the Meas key, the Measure icon begins flashing.
1.6 Wait for the reading to stabilize, the Measure icon will stop flashing.
Press the Meas key, the meter takes a measurement again.
Single measurement - high turbidity samples (>1100 NTU)
For the high turbidity samples, the solution must be diluted prior to measurement. The dilution water can be obtained by filtering
deionized water through a < 0.45µm filter membrane.
2.1 Repeat steps 1.1 through 1.5 above and record the measured value.
2.2 Calculate the true turbidity of the original sample using the following formula.
T =
Continuous measurements
3.1 Ensure that the meter is in the continuous measurement mode (Refer to page 8 “Selecting the measurement mode”).
3.2 Fill the vial with the sample. Cap the vial.
3.3 Gently invert the vial several times to mix the sample.
3.4 Wipe the vial with the lint-free cloth to remove waterdrops and fingerprints.
3.5 Place the vial in the measurement chamber. Align the mark on the vial with the arrow on the meter.
3.6 Close the light shield lid. Press the Meas key, the Measure icon begins flashing, the meter continuously measures the sample.
To stop the measurement, press the Meas key again.

4. Press the ◄ key to select the / .
5. Press the Enter key to confirm.

Appendix
Indexing a sample vial
The United States Environmental Protection Agency (U.S. EPA) recommends that the vial used for turbidity calibration or sample
measurement be indexed. Its purpose is obtain a position which provides the lowest turbidity reading. The indexing methods are
as follows.
1. Fill the vial using the distilled water (< 0.5 NTU). Cap the vial.
2. Wipe the vial with the lint-free cloth to remove waterdrops and fingerprints.
3. Place the vial in the measurement chamber. Align the mark on the vial with the arrow on the meter.
4. Press the Meas key, the meter begins the measurement.
5. Slowly rotate the vial approximately 45 degrees. Close the light shield lid and record the measured value.
6. Repeat the step 5 until the lowest turbidity reading is shown.
7. Mark this position on the vial.
Matching the sample vials
For the best accuracy and repeatability, using one indexed vial is best choice for turbidity measurement. If you need to use a few
vials, match
these vials are necessary.
1. Repeat the steps above for each vial and record the measured values.
2. Find the closest position of these vials measuring value and mark it.
Preparing the formazin standards
Preparation of turbidity-free water:
The turbidity-free water is used for preparation of turbidity standards and is prepared by filtering deionized water through a
0.45µm or smaller pore-sized membrane.
