  • Page 5: Principle Of Operation

    The optical system of HI 83215 is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.

  • Page 6: Functional Description

    The measurement process is carried out in two phases: first the meter is zeroed and then the actual measurement is performed. The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both the measurement and the calibration (zeroing) cuvette are optically identical to provide the same measurement conditions.

  • Page 7: Tips For An Accurate Measurement

    1) Open Cuvette Lid 2) Indexing mark 3) Cuvette point 4) Liquid Crystal Display (LCD) 5) Splash proof keypad 6) ON/OFF power switch 7) Power input connector 8) USB connector KEYPAD DESCRIPTION The keypad contains 8 direct keys and 3 functional keys with the following functions: Press to perform the function displayed above it on the LCD.
  • Page 8 (b) pull the plunger up until the lower edge of the seal is exactly on the 0.0 mL mark. (c) take out the syringe and clean the outside of the syringe tip. Be sure that no drops are hanging on the tip of the syringe, if so eliminate them. Then, keeping the syringe in vertical position above the cuvette, push the plunger down into the syringe until the lower edge of the seal is exactly on the 0.5 mL mark.
  • Page 9 USING CUVETTES • Proper mixing is very important for reproducibility of the measurements. The right way of mixing a cuvette is specified for each method in the related chapter. (a) invert the cuvette a couple of times or for a specified time: hold the cuvette in the vertical position. Turn the cuvette upside-down and wait for all of the solution to flow to the cap end, then return the cuvette to the upright vertical position and wait for all of the solution to flow to the cuvette bottom.

  • Page 10: Health & Safety

    • In order to avoid reagent leaking and to obtain more accurate measurements, close the cuvette first with the supplied HDPE plastic stopper and then the black cap. • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and free of fingerprints, oil or dirt.

  • Page 18 IRRIGATION WATER (LOW RANGE) In agricultural areas it is quite common to find altered values in the chemical composition of irrigation waters. The problem concerns mostly the high nitrate concentration, usually determined by excessive fertilization or irrational liquid manure spreading. The analysis of irrigation waters allows us to find out which are the substances present in major or minor quantity and to organize an advantageous fertilization plan.

  • Page 19: Sample Preparation

    SAMPLE PREPARATION SAMPLE PREPARATION PROCEDURE Note: If the water sample to be analyzed is very turbid, let it stand in a beaker for a while until most of the solid particles have settled. Then, use the pipette to transfer the supernatant solution to the other beaker and prepare the samples as described below.
  • Page 20 • Fold a filter disc twice as shown in the figure. Separate one side from the other three to form a cone. Insert the folded filter disc in the funnel. • Filter the treated sample into an empty beaker. The sample is now ready. Note: Filter at least 40 mL of solution if all the four methods will be tested.
  • Page 21 • Replace the cap and shake gently for at least 2 minutes. • Open the upper part of the Demineralizer Bottle cap and gently squirt the demineralized water into the cylinder, up to the 100 mL mark. Note: The ion exchange resin contained in the Demineralizer Bottle is provided with an indicator substance.
  • Page 22 Note: To measure exactly 5 mL of sample with the syringe, push the plunger completely into the syringe and insert the tip into the sample. Pull the plunger out until the lower edge of the seal is on the 5 mL mark of the syringe. •...
