About Chlorine Assay Kit

A Chlorine Assay Kit is a test used to determine the chlorine level in a human serum sample. The test is primarily used as an auxiliary diagnosis for hypochloraemia and hyperchloraemia. Increased serum chlorine levels are common in diseases such as natriemia and metabolic acidosis, while decreased levels are found in conditions such as excessive loss of urine and spleen.

HANNA Free Chlorine Test Kit

If you're in need of a free chlorine test kit, the HANNA HI 701 is the perfect tool. Its hand-held design is both compact and portable, and the digital colorimeter's technology provides more accurate readings than conventional chemical tests. The Checker's design also provides an automatic shutoff function and an easy-to-read LCD screen. The HI701 is supplied as a complete set, including two trays with a lid, powdered reagent for six tests, and a quick user's guide.

The Hanna HI3831F is a colorimetric chemical test kit that determines free chlorine concentrations in water samples within a range of 0.0 to 2.5 mg/L. It comes complete with the reagents, equipment, and instructions needed to perform around 50 tests. To test the chlorine level in water, simply add the reagents to the water and compare the color. This kit provides reagents that are easy to mix and use, and includes markings and expiration dates. It also provides a cube for color comparison and a 20-mL reagent.

FAS-DPD method

The FAS-DPD method for chlorine assasin is a chemical technique that measures the total and free chlorine content of a sample. The titration test kit measures total and free chlorine levels in increments of 0.2 ppm. A distinct color change in the sample indicates the amount of chlorine in the sample. The method can measure levels as low as 0.2 ppm or as high as 20 ppm.

The FAS-DPD method is the most accurate way to measure free chlorine in a pool or spa. DPD produces a pink color and is usually used in conjunction with OT. However, OT is only useful for measuring total chlorine and cannot measure residual chloride. In most of the United States, health departments no longer allow the use of this method for regulated facilities. This method is more sensitive and more accurate than OT.

Color wheel test kits

The use of a color wheel test kit is not limited to the home. A variety of commercial and municipal testing facilities offer this kit. Using a powdered chemical known as DPD, which turns pink in the presence of chlorine, these kits are less expensive and simpler to use than digital meters. The color wheel can measure both free chlorine and total chlorine. The kit's range is 0 - 3.5 mg/L.

The most common color wheel test kit uses three main reagents, which are phenol red, methylene blue, and cyanocobalamin. They have been around since the early 1900s and are marketed to homeowners and commercial pool service providers. The five-way test kit is an example of this type of kit. The tester adds five drops of a reagent to the sample water in the comparator tube and then compares the results to the colour scale. This process is known as a colorimetric test.
