The YSI 251398Y DPD Free Chlorine Reagent Powder is designed for accurate measurement of free chlorine in water samples using a compatible colorimeter. Each pack contains 100 individual powder packs, with each pack formulated for a 5ml sample volume and capable of measuring free chlorine in the range of 0 to 3.5 mg/L.
This reagent utilizes the DPD (N,N-Diethyl-p-phenylenediamine) method, which reacts with free chlorine to produce a magenta color, the intensity of which is proportional to the chlorine concentration and measured by a colorimeter.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Follow these steps to accurately measure free chlorine using the YSI 251398Y DPD Free Chlorine Reagent Powder:
- Sampശേഖരം: ഒരു ശുദ്ധജലം ശേഖരിക്കുകample in a clean sample cell. The required volume is 5ml. Ensure the sample is representative of the water being tested.
- റീജന്റ് ചേർക്കുക: Carefully tear open one YSI 251398Y DPD Free Chlorine Reagent Powder pack. Add the entire contents of the powder pack to the 5ml water samps ലെ leampലെ സെൽ.
- മിക്സ്: ക്യാപ് ദി എസ്ample cell and invert several times to thoroughly mix the reagent with the sample. Ensure all powder dissolves completely. A magenta color will develop if free chlorine is present.
- പ്രതികരണ സമയം: Allow a reaction time of 1 minute for the color to fully develop. Do not exceed 6 minutes, as color fading may occur, leading to inaccurate results.
- അളവ്: Insert the prepared sample cell into your calibrated colorimeter. Follow your colorimeter's instructions to initiate the measurement. The colorimeter will display the free chlorine concentration in mg/L.
- റെക്കോർഡ് ഫലങ്ങൾ: Record the measured free chlorine concentration.
