MEASUREMENT PROCEDURE
• Select the program number corresponding to Nickel LR on the
secondary LCD by pressing PROGRAM W and V.
Note: for best results perform your tests between 20-24°C.
• Fill one graduated beaker with 25 mL of
deionized water (blank) and another one with
25 mL of sample.
• Add the content of one packet of HI 93740A
Phthalate-phosphate reagent to each beaker.
Cap and swirl gently until the reagent is
dissolved.
