Calibrate the turbidimeter with StablCal Standards
Calibrate the turbidimeter before it is used for the first time using the StablCal sealed vial standards
provided.
Calibrate the turbidimeter at least every 3 months or as specified by the regulating authority when
data is used for ISO 7027 reporting.
Note: Unknown results may occur if standards other than the recommended calibration points are used. The
recommended calibration points (< 0.1, 20, 200 and 1000 NTU) provide the best calibration accuracy. Use of
standards other than StablCal, or user-prepared formazin, may result in less accurate calibrations. The
manufacturer cannot guarantee the performance of the instrument if calibrated with co-polymer
styrenedivinylbenzene beads or other suspensions.
Calibration notes
• Make sure that the instrument is in the same ambient conditions as where it is used.
• Make sure that the standards are at the same ambient temperature as the instrument before use.
• Use only the provided silicone oil. This silicone oil has the same refractive index as the vial glass
and masks minor glass differences and scratches.
• Store the oiling cloth in a plastic storage bag to keep the cloth clean.
• If power is lost during calibration, the new calibration data is lost and the last calibration data is
used.
• In Calibration mode, automatic range and signal averaging on are selected. When calibration is
completed, all operational modes go back to the last settings.
• All nephelometric (turbidity units of measure) calibrations are done at the same time.
• The FNU values of StablCal standards and formazin standards are calculated using the
conversion factors of 1 FNU = 1 NTU.
Configure the calibration settings

Turbidity measurement
For accurate turbidity readings use clean sample cells and remove air bubbles.
16 English

Measurement notes
Proper measurement techniques are important in minimizing the effects of instrument variation, stray
light and air bubbles. For accurate and repeatable measurements:
Instrument
• Make sure that the instrument is on a level, stationary surface that is free of vibration during the
measurement.
• Instrument stabilization is immediate. No warm-up time is necessary.
• Always close the sample compartment lid during measurement, calibration and verification.
• Remove the sample cell from the instrument and turn off the instrument if the instrument is stored
for an extended time period (more than a month).
• Keep the sample compartment lid closed to keep dust and dirt out.
Sample cells
• Always cap the sample cell to prevent spillage of the sample into the instrument.
• Always use clean sample cells in good condition. Dirty, scratched or damaged cells can result in
readings that are not accurate.
• Make sure that cold samples do not “fog” the sample cell.
• Store sample cells filled with distilled or deionized water and cap tightly.
• For the best accuracy, use a single sample cell for every measurement or a flow cell.
Note: As an alternative, matched sample cells may be used for measurements but do not provide as good of
accuracy or precision as a single indexed sample cell or flow cell. When using matched sample cells, align the
orientation mark on the sample cell with the reference mark on the sample cell holder.
Measurement
• Measure samples immediately to prevent temperature changes and settling. Before a
measurement is taken, always make sure that the sample is homogeneous throughout.
• Avoid sample dilution when possible.
• Avoid instrument operation in direct sunlight.
