LH2002; DPD Residual Chlorine Water Quality Test Kit 0.05-1mg/l

Estimated delivery : 30 Days; MOQ : 1 Box (1 box = 50 Times)
Product Introduction Overview
Product application: tap water, well water, swimming pool water quality testing, hospital dialysis room residual chlorine residual testing, aquaculture water quality testing, 84 disinfectant residual testing, etc.

Directions :
Take a clean colorimetric tube and add the water sample to the scale line (15mL) of the tube. Pour the residual chlorine determination reagent into the colorimetric tube and shake it until it is completely dissolved. Then lift the tube to a height of about 2 cm from the colorimetric card and compare the color with the standard color scale from top to bottom. The color scale with the same color tone as the solution in the tube is the residual chlorine content in the water (mg/L).

Note:
The pH value of the water sample to be tested is 5.08.0 and the temperature is 1525℃
The presence of other oxidants will interfere with the determination
Colorimetry should be completed within 5 minutes after adding the reagent
The specific operation shall be subject to the instructions that come with the product.

Precautions Notices
The pH value should be controlled at 5-8
Oxidants: bromine, iodine, amine, iodine amine, ozone, hydrogen peroxide, chromate, manganese oxide, etc.

Reducing agent: nitrite, etc.

If the alkalinity of the water exceeds 250mg/l and the acidity exceeds 150mg/l, the measured value will be unstable during the measurement process, and the sample color will disappear or become very light. Adding diluted HCl or NaOH to neutralize the sample can solve this problem.

The color of the liquid itself will also interfere. Activated carbon can be used for decolorization
