How to use?
Aluminum Test specification
1.Fill a clean test tube with sample to the 10-mL mark.
2. Add 1mL Aluminum () Reagent to the tube, swirl to mix.
3.Add the contents of one Aluminum () Reagent to the tube, cap the tube and shake to dissolve, stand for 5 minutes.
4. Add the contents of one Aluminum () Reagent to sample and swirl to dissolve.5. Place the tube in 1 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 aluminum in the sample.
Notes:
1.Sample pH : 4.0-7.0, temperature: 20-40.
2.When the concentration of Fe3+ exceeds 0.4mg/L or the concentration of Cu2+ exceeds 0.05mg/L in the sample, please add 0.01 g ascorbic acid before testing.
3.In step 4, swirl slowly to avoid forming foam.
Package: 50 test / box
1.R & D team to provide technical support.

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.
