K-2520D Chlorine

Why Choose HR CHEMets kits?

HR CHEMets^®  is the new way to test at high ranges and replaces the now discontinued VACUettes product line. This product's measurement ranges overlaps with the discontinued K-2504D test kit. 

The K-2520D Chlorine HR CHEMets^®  Test Kit (0-25 ppm) comes in a plastic case and contains everything needed to perform 30 tests (except distilled water): R-2500 CHEMets^®  Refill, C-2506 Comparator, A-2500 Activator Solution, 25 mL sample cup, A-0104 10mL syringe, and instructions.

What's Included:

Method:

The Chlorine CHEMets®1 test kits employ the DPD chemistry.2,3 Free chlorine oxidizes DPD (N,N-diethyl-pK-2520D/R-2500: 0 - 25 ppm Free Chlorine Procedure 1. Using the syringe provided, obtain 5 mL of the sample to be tested, and then dispense it into the empty sample cup. 2. Dilute the contents of the sample cup to the 25 mL mark with distilled water  (fig. 1). 3. Place the CHEMet ampoule, tip first, into the sample cup. Snap the tip. The ampoule will fill leaving a bubble for mixing (fig. 2). 4. To mix the ampoule, invert it several times, allowing the bubble to travel from end to end. 5. Dry the ampoule. Obtain a test result  1 minute after snapping the tip. 6. Obtain a test result by placing the ampoule between the color standards until the best color match is found (fig. 3). NOTE: Use the 0 - 25 ppm concentration scale on the comparator label. Total Chlorine Procedure 1. Perform steps 1 - 2 of the Free Chlorine Procedure. 2. Add 5 drops of S-2500 Activator Solution. Stir briefly. 3. Immediately perform steps 3 - 6 of the Free Chlorine Procedure using this pretreated sample. phenylenediamine) to form a pink colored species in direct Figure 1 Figure 2 Figure 3 proportion to the chlorine concentration. Total chlorine, the sum of free and combined chlorine, is determined by adding an excess of potassium iodide to the sample. Chloramines (combined chlorine) oxidize the iodide to iodine. The iodine then oxidizes DPD to the pink colored species. Other halogens, ozone and halogenating agents will produce high test results. Chlorine at concentrations significantly above the test range may prevent proper color development, causing low test results.

1. Place a pipette tip firmly onto the end of the MiniPet®4 (fig. 1). Note: Use a fresh pipette tip for each test.	2. Depress the plunger on the minipet. Immerse the tip in the sample to be tested and release the plunger. A portion of the sample will be drawn into the tip (fig. 2).
3. Hold the minipet over the empty sample cup, and depress the plunger to dispense sample (fig. 3).	4. Dilute the contents of the sample cup to the 25 ml mark with distilled water (fig. 4).
5. Add solutions to the sample cup in the following order (fig. 5). 5 drops S-1404 Stabilizer 5 drops S-1405 Catalyzer (green) 5 drops S-1406 Activator (blue)	6. Immediately place the CHEMet ampoule, tip first, into the sample cup. Snap the tip. The ampoule will fill leaving a bubble for mixing (fig. 6). To mix the ampoule, invert it several times, allowing the bubble to travel from end to end. Dry the ampoule. Obtain a test result  5 minutes after snapping the tip.
7. Obtain a test result by placing the ampoule between the color standards until the best color match is found (fig. 7). NOTE: Use the concentration scale on the comparator label that corresponds to the range of the test procedure being used.	0 - 10,000 ppm Test Procedure Using the syringe provided, obtain 3 mL of the sample to be tested and dispense it into the empty Sample Prep Cup. 2. Dilute to the 15 mL mark with distilled water. Perform the entire 0 - 2000 ppm Test Procedure using this pre-diluted sample.
