How to use?

Chlorine (Total) Test Specification

1.   Fill a clean test tube with sample to the 15-mL mark

2.   Add the contents of one DPD-Chlorine (Total) Reagent to the tube, cap the tube and shake to dissolve

3.   Open the cap, place the tube in 2 cm above the blank of standard card, compare the color from top to bottom, the standard color level has the same color as observed from the tube shows the concentration of chlorine (total) in the sample.

 

Notes
 

1.  Water sample pH : 5.0-8.0, temperature: 15-25

2.  The presence of other oxidizing substance will cause a positive interference to the result

3.  Complete the test within 5minutes after adding the DPD reagent.

FAQ

Q1: When doing hardness testing of water samples ,why color keep unchanged after  adding 100ml of water ?
A1: The hardness of the water sample may belong to low hardness,it out of testing range range of reagents, lower hardness reagent is recommended to be used.
 

Q2: When doing chlorine (or ozone, total chlorine) testing of for water samples,the longer time, the deeper the color, and why?
A2: Because the containing DPD reagent may react with the air oxidation, it is proposed in strict accordance with the test instructions, to control the reaction time.

 

Q3: Why the water sample shows pink after adding DPD chlorine (or total chlorine, ozone) reagent ,and then faded to become colorless?
A3: The reason may be that the concentration of chlorine (total chlorine, ozone) in the water is too high, dilution is recommended before testing.
