Page 4: General Description
GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION HI 83414 is a high accuracy, combined meter that benefits from Hanna’s years of experience as manufacturer of analytical instruments. The HI 83414 successfully combines turbidity and colorimetric measurements to meet the needs of measuring the most important parameters of drinking water: turbidity and free/total chlorine. -

This algorithm corrects and compensates for interferences of color, making the HI 83414 instrument color-compensated. The optical system and measuring technique compensate also for the lamp intensity fluctuations, minimizing the need of frequent calibration.
- Page 7 Where: –log I/I = Absorbance (A) = intensity of incident light beam = intensity of light beam after absorption = molar extinction coefficient at wavelength = molar concentration of the substance = optical path through the substance Therefore, the concentration “c” can be calculated from the absorbance of the substance as the other factors are known.

If this is not possible always match the cuvets. In turbidimetric measurements, if you are using multiple cuvets, always match the cuvets. CUVET HANDLING The cuvets should be free of scratches or cracks.
- Page 13 Note: The supplied cloth for oiling should be stored together with the silicone oil bottle and cuvets, 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 cuvet to provide the necessary oil quantity in the cloth.
- Page 14 • Insert the cuvet into the instrument and press “Read” functional key. Record the reading. • Open the instrument lid, slightly rotate the cuvet and take a new reading. • Repeat the last step until you read the lowest NTU value.
- Page 15 • Turn the instrument ON. • Insert the first cuvet into the instrument and press “Read” functional key. Record the reading. • Mark this position on the thicker white band on the top of the cuvet with a water resistant pencil. •...
- Page 16 • Alternatively, keep the “Read” functional key pressed and, after the first value is displayed, open the lid and start rotating the cuvet until the read value matches the first cuvet. • Mark this position on the second cuvet with a water resistant pencil. •...
- Page 17 ADDITION OF SURFACTANT 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 cuvet before adding the sample to be analyzed.
- Page 18 REAGENT ADDING (COLORIMETRY only) • Because the reagent quantity is set up to react with 10mL of sample is very important to fill the cuvet correctly. The liquid in the cuvet forms a convexity on the top; the bottom of this convexity must be at the same level with the 10 mL mark.
