  • Page 12: General Tips For An Accurate Measurement

    GENERAL TIPS FOR AN ACCURATE MEASUREMENT HI 83414 is a highly accurate combined meter for turbidity and free & total chlorine. To meet the instrument’s performance and fully benefit from its features, it is very important for the analyst to use proper measurement techniques for accurate, precise and repeatable readings.
  • Page 13 Note: In colorimetric measurements, when it is possible, use the same cuvette both for zeroing and measurement. If this is not possible, always match the cuvettes. In turbidimetric measurements, if you are using multiple cuvettes, always match the cuvettes. CUVETTE HANDLING The cuvettes should be free of scratches or cracks.
  • Page 14 Note: The supplied cloth for oiling should be stored together with the silicone oil bottle and cuvettes, taking care to avoid contamination with dirt. After a few oiling procedures, the cloth will contain enough oil to wipe the bottle with it without adding more oil. From time to time add some drops of oil on the cuvette to provide the necessary oil quantity in the cloth.
  • Page 15 • Insert the cuvette into the instrument and press the Read key. Record the reading. • Open the instrument lid, slightly rotate the cuvette and take a new reading. • Repeat the last step until you read the lowest NTU value. •...
  • Page 16 • Turn the instrument ON. • Insert the first cuvette into the instrument and press the Read key. Record the reading. • Mark this position on the thicker white band on the top of the cuvette with a water resistant pencil.
  • Page 17 • Alternatively, keep the Read key pressed and, after the first value is displayed, open the lid and start rotating the cuvette until the read value matches the first cuvette. • Mark this position on the second cuvette with a water resistant pencil. •...
  • Page 18 ADDITION OF SURFACTANT A surfactant addition works by changing the surface tension of the water. In this way bubbles are released from the sample. This method is effective in samples that are supersaturated with air. The procedure consists in the addition of a drop of surfactant in the cuvette before adding the sample to be analyzed.
  • Page 19 ADDING REAGENT (COLORIMETRY only) • Because the reagent quantity is set up to react with 10 mL of sample, it is very important to fill the cuvette correctly. The liquid in the cuvette forms a meniscus; the bottom of the meniscus must be at the same level with as the 10 mL mark.

  • Page 20: Start Up

    START UP The HI 83414 Turbidity / Free & Total Chlorine benchmeter is supplied with all necessary accesories for making measurements. Unpack the instrument and place it on a flat surface. Do not place the instrument under direct sunlight. Connect the instrument to the mains with the provided power cord. Pay attention that the mains voltage match the value printed on the back of the instrument.

  • Page 22: Measurement Procedure For Ratio/Non Ratio Turbidity Range

    MEASUREMENT PROCEDURE FOR RATIO / NON RATIO TURBIDITY RANGE When taking turbidity measurements, several basic rules should be followed: • Never use cuvettes with scratches or cracks because they can cause inaccurate readings. • Always cap the cuvettes to avoid spillage of the sample into the instrument. •...
  • Page 23 NORMAL MEASUREMENT This type of measurement is best suited for regular readings, when the sample is stable and normal accuracy is required. In normal mode, the measurement takes about 10 seconds and the lamp is ON for a minimum period of time (about 7 seconds). •...
