Chlorine In Water Testing Equipment

TEST METHODS AVAILABLE


COLORIMETRIC


	Tests which determine the concentration of a substance are based on Beer's Law. Simply stated, this says that the higher the concentration of a substance, the darker the color developed in the test, so more light is absorbed by the sample.


	There are two basic styles of manual block comparators as illustrated below. When reviewing these kits available, the Test Method Column will state what style of block comparator the kit consists of.


	Octet Comparator


	The Octet Comparator contains eight color standards with built-in filters which eliminate optical distortion. The color standards are arranged so that the sample can be compared to four standards at once.

		Octa-Slide Comparator


	The eight color standards in the Octa-Slide are placed in a bar so that they can be compared to the sample individually.


	Digital Electronic Chlorine Colorimeters

Electronic colorimeters measure the amount of light which travels through the reacted sample, and convert the measurement to a reading as ppm.

There are Single Test and Multiple Testing Electronic Colorimeters available.

Test Strips


	Test strips are either dipped or swirled in test solutions. The resulting color reaction is compared to a color chart provided.

Titrimetric


	Titrimetric tests can be used to determine the concentration of chlorine in a sample solution. For testing higher total chlorine levels, this method is used. After the sample is treated with an indicator, a standard titrant is added until a color change indicates a completed reaction. LaMotte offers four separate types of titration methods, allowing a choice of precision and convenience.


	The Direct Reading Titrator is a 1.0 mL microburet calibrated to allow direct reading of the test result. Each Titrator has a specific range, but may be refilled to test higher concentrations.


	Dropper Pipet


	The drop count test uses a pipet to provide fast, reliable measurements in the field. The number of drops used to obtain a color change is multiplied by a given factor to produce the test result.


	Automatic Buret


	The self-zeroing automatic buret is calibrated from 0 to 10 mL in 0.1 mL increments. It is available with a squeeze valve (pinchcock), glass stopcock, or Teflon® stopcock.


	Dropper Bottle

		The dropper bottle test uses bottle tips which deliver a consistent standard drop size to add titrant to the sample. As with the drop count test, the number of drops used to complete the reaction is multiplied by a given equivalence factor to determine the concentration. Many dropper bottle tests use different sample sizes for different equivalences.

Chlorine

Free, combined, and total chlorine may be determined using DPD with either colorimetric or titrimetric methods. These determinations are generally limited to concentrations of 0-10 ppm, although the FAS titration can test higher concentrations with the addition of more DPD indicator.

Higher concentrations of chlorine require the iodometric titration, whereby the sample is acidified and iodide is added, which is oxidized by chlorine to iodine and is titrated with a standard thiosulfate solution.
