•No potential magnetic fields and ambient light interference.
The following list describes the standard components of meter. After the unpacking, please check all components are complete. If any are
damaged or missing, please contact the supplier.
The sample vial in the measurement chamber has been indexed with the 0.02 and 10 NTU standards at the factory.
Operating principles
The TB100 portable turbidity meter operates on the nephelometric principle of turbidity measurement and is designed to meet the criteria specified
in ISO 7027. The following figure shows the basic optical system of meter. It includes a light source and a detector to monitor the light scattered
at 90° with respect to the incident beam.

Measurement and Calibration
Measurement and Calibration Hints
•Do not hold the meter in the hand during the measurement and calibration.
•Ensure that the sample in vial is homogeneous and preventing air bubbles.
•Before starting the measurement, the outside of vial must be clean and dry. Wipe the vial with a lint-free cloth to remove fingerprints and
waterdrops.
•If the vial has minor scratches or scuffs, add a few drops of silicone oil to outside of the vial. Wipe with lint-free cloth.
•Ensure that the vial is positioned in the measurement chamber, the mark on the vial must be aligned with the arrow on the meter.
•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 TB100 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.
Setting the number of calibration points
1.1 Press and hold the key for 3 seconds to enter the setup menu, the display shows / .
1.2 Press the Enter key, the display shows / (2 points calibration).
1.3 Press the ◄/ ►key to select the number of calibration points, press the Enter key to confirm.

calibration point close to the sample value you are measuring.
2.2 Take out the corresponding calibration standard from carrying case. Wipe the vial with a lint-free cloth to remove fingerprints.
2.3 Hold the vial cap and gently inverting vial several times. Ensure that the calibration standard is homogeneous and no air bubbles.
2.4 Insert the calibration standard into the measurement chamber, the mark on the vial cap aligns with the arrow on the meter. Close the light
shield lid.
2.5 Press the Enter key, the meter begins the calibration. The Calibration icon continuously flashing.
2.6 Wait for the reading to stabilize, the meter automatically shows the next calibration point.
2.7 If necessary, press the ►key to select an applicable calibration point.
2.8 Repeat steps 2.2 through 2.5 until the meter shows . Calibration is completed.
To exit the calibration mode without saving the calibration, press the Meas key.
Turbidity Measurement
Selecting the measurement mode
The TB100 portable turbidity meter contains two measurement modes. If the single measurement mode is enabled, the meter will automatically
recognize a stable reading and lock the measurement. If the continuous measurement mode is enabled, the meter will continuously updating the
measured values. To set this option follow the steps below.
1. Press and hold the key for 3 seconds to enter the setup menu.
2. Press the ►key until the display shows / (Hold/Page 5).
3. Press the Enter key, the display shows / indicating that the single measurement mode is selected.
4. Press the ►key, the display shows / indicating that the continuous measurement mode is selected.
5. Select one of the above options, press the Enter key to confirm.

Measurement and Calibration
Measurement
An accurate turbidity measurement depends on good measurement techniques. Factors such as clean sample vials, positioning of vial in the
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 will take 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 < 0.45µ m 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.
