REQUIRED REAGENTS Code HI 93722-0 REAGENT SETS HI 93722-01 Reagents for 100 tests HI 93722-03 Reagents for 300 tests For other accessories see page 128. MEASUREMENT PROCEDURE · Select the Cyanuric Acid method using the procedure described in the Method Selection section (see page 12). · Fill the cuvette with 10 mL of unreacted sample (up to the mark) and replace the cap. · Place the cuvette into the holder and close the lid. The meter will show "-0. 0-" when the meter is zeroed and ready for measurement. 10 mL · Fill a graduated beaker up to the 25 mL mark with the sample, add the content of one packet of HI 93722-0 reagent and swirl gently to mix. Cyanide 54 55 Cyanuric Acid · Fill a second cuvette with 10 mL of the reacted sample up to the mark. Replace the cap. 10 mL FLUORIDE SPECIFICATIONS Range Resolution Accuracy Typical EMC Deviation Light Source Method 0. 00 to 2. 00 mg/L 0. 01 mg/L ±5% of reading ±0. 01 mg/L Tungsten lamp with narrow band interference filter @ 575 nm Adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, SPADNS method. The reaction between fluoride and the liquid reagent causes a red tint in the sample. Description SPADNS Reagent Quantity 4 mL · Reinsert the cuvette into the instrument. · Press TIMER and the display will show the countdown prior to the measurement or, alternatively, wait for 45 seconds and press READ. When the timer ends the meter will perform the reading. REQUIRED REAGENT Code HI 93729-0 REAGENT SETS · The instrument displays concentration in mg/L of cyanuric acid. HI 93729-01 Reagents for 100 tests HI 93729-03 Reagents for 300 tests For other accessories see page 128. MEASUREMENT PROCEDURE · Select the Fluoride method using the procedure described in the Method Selection section (see page 12). · Add 2 mL of HI 93729-0 SPADNS Reagent to two cuvettes. · Fill one of the cuvettes with distilled water up to the mark, replace the cap and invert several times to mix. 10 ml 2 ml 10 ml · Fill the other cuvette with sample up to the mark, replace the cap and invert several times to mix. #1 #2 · Place the cuvette with the reacted distilled water (# 1) into the holder and close the lid. #1 Cyanuric Acid 56 57 Fluoride · Press TIMER and the display will show the countdown prior to zeroing the blank or, alternatively, wait for two minutes and press ZERO. The display will show "-0. 0-" when the meter is zeroed and ready for measurement. CALCIUM HARDNESS SPECIFICATIONS Range Resolution Accuracy Typical EMC Deviation Light Source Method 0. 00 to 2. 70 mg/L 0. 01 mg/L ±0. 11 mg/L ±5% of reading ±0. 01 mg/L Tungsten lamp with narrow band interference filter @ 525 nm Adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, Calmagite method. The reaction between calcium and reagents causes a reddish-violet tint in the sample. Description Ca & Mg indicator Alkali solution EGTA solution Quantity 0. 5 mL 0. 5 mL 1 drop REQUIRED REAGENTS · Remove the cuvette. · Insert the other cuvette (# 2) with the reacted sample into the instrument. The instrument displays the results in mg/L of fluoride. #2 Code HI 93720A-0 HI 93720B-0 HI 93720C-0 REAGENT SETS HI 93720-01 Reagents for 100 tests HI 93720-03 Reagents for 300 tests For other accessories see page 128. MEASUREMENT PROCEDURE · Select the Calcium Hardness method using the procedure described in the Method Selection section (see page 12). Note: For wastewater or seawater samples, before performing measurements, distillation is required. For most accurate results, use two graduated pipettes to deliver exactly 8 mL of distilled water and 8 mL of sample. · Rinse a graduated beaker several times with unreacted sample, before filling it to the 50 mL mark with the sample. INTERFERENCES Interferences may be caused by: Alkalinity (as CaCO3) above 5000 mg/L Aluminum above 0. 1 mg/L Iron, ferric above 10 mg/L Chloride above 700 mg/L Phosphate, ortho above 16 mg/L Sodium hexametaphosphate above 1. 0 mg/L Sulfate above 200 mg/L Highly colored and turbid samples may require distillation Highly alkaline samples can be neutralized with nitric acid. 58 · Add 0. 5 mL of HI 93720A-0 Calcium indicator solution and swirl to mix. #1 #2 · Add 0. 5 mL of HI 93720B-0 Alkali solution and swirl to mix. Use this solution to rinse 2 cuvettes before filling them up to the 10 mL mark. Fluoride 59 Hardness Ca · Press the Unit functional key to change the current measurement unit. The results can be converted to French degrees (°f), German degrees (°dH) and English degrees (°E). · Add 1 drop of HI 93720C-0 EGTA solution to one cuvette (# 1), replace the cap and invert the cuvette several times to mix. This is the blank. #1 · Press the · Place the blank (# 1) into the holder and close the lid. [. . . ] When shipping any instrument, make sure it is properly packaged for complete protection.
