Product Description

Product Description

Principle
Based on the national standard EDTA titration method(also known as "ethylenediaminetetraacetic acid titration").EDTA (ie, ethylenediaminetetraacetic acid) is a strong complexing agent that can form stable complexes with many metal ions. The method can measure about 70 elements directly or indirectly. Most commonly used to determine calcium and magnesium.

 

Applications
Used in analysis of hardness in softened water, boiler water, condensation water and reverse osmosis water,etc.

Features
1.Quick and easy
Operating in accordance with the instructions, users can complete the low hardness test independently without specialized
training.5 minutes is enough to complete the analysis of one water sample.
2.Accurate and reliable
Determination results with this method are in accordance with the results with the standard method. It can be used as an
alternative method to the standard method.
3.Quantitative packing
The kit can be used for 50 times. It is small, light and easy to carry.

Specification

Testing range: 0.4 mg/L~20mg/L (as CaCO3).

6: I purchased DPD reagent with gray spots, is it normal?
A: DPD residual chlorine, total chlorine, ozone reagent kits supporting the reagents are tablets. Due to the differences in the
color of the DPD material, the color of the product may be white, light gray or pale pink. If the tablet is dark, sticky, do no
use it .

7:How often should the measurement be completed?
A: Because DPD residual chlorine, total chlorine, ozone reagents react with the oxidizing substances in the air, resulting in
color deepening. Therefore, we suggest to finish the testing within 5 minutes after the addition of the reagent.

8:What are the factors in the water that interfere with the measurement?
• Oxidizing agents: bromine, iodine, bromamine, iodine, ozone, hydrogen peroxide, chromate, manganese oxide.
• Reducing agent: nitrite etc..
