Fast, accurate visual method for determining chlorine concentrations. If you think theres high metal content (as little as 1 ppm metal can cause staining), its best to consider a metal kit. DDPD reacts with free chlorine to form a purple product. Adding DPD #3 to the treated sample gives you the total chlorine reading. Next, an organic dye is added that turns red when it reacts with calcium. Then add 4.5 mL of water that has NO chlorine in it (bottled water usually doesnt contain chlorine). One way to set your pool apart from the competition is reassuring recreational and competitive swimmers that you routinely test and analyze water quality and chemicals. To get the reading, the number of drops used to cause this color change is multiplied by the appropriate factor for the size of the water sample (supplied by the manufacturer). /8A%373'Q-=EPu"UK>=JZLH>*}~C9@q]a%E2kRb[jr The turbidity is then measured against a comparator chart depicting the relative visibility of a dot in the test vial, thereby indicating the corresponding CYA reading in parts per million. The majority of calls are about the same topics, and I often get asked the same questions: Why am I getting a zero or very low chlorine reading when I know theres plenty of chlorine in the water? What is the proper way to hold a dropper bottle when dispensing drops? Where did that weird color stain in my pool come from?. Up to 50 data sets can be stored on the instruments memory, and it has a live clock meaning the exact date and time is saved for each measurement, allowing for full traceability for compliance and auditing purposes. Taylor Water TechnologiesLLC ISO 9001:2015 Certified. The number of drops required to cause a color change in the water sample correlates to a chart that prescribes the amount of muriatic acid (to lower pH) or soda ash (to raise it) needed to move the pH. The resulting colors yellow (low), red (middle) and purple (high) will be accurate in a pH range of 6.8 to 8.4. This variation of the traditional DPD method allows users to measure both free and combined chlorine levels as low as 0.2 ppmthe maximum allowable level for combined chlorine according to most health authorities as well as the Pool & Hot Tub Alliance (PHTA)and as high as 20 ppm.
A buffered DPD indicator powder is added to a water sample and reacts with chlorine to produce the pink color characteristic of the standard DPD test. Option A: Continue to add level scoops of FAS-DPD Indicator Powder until the pink/red color stops bleaching out. The number of drops required to turn the sample blue correlates to hardness in ppm. You can train all your team members to use the kit so they're able to quickly assess the quality and safety of the water in pools and water parks. Make a color match and multiply that value by 2 for your free chlorine reading. Higher concentrations produce far more particles and turn the water very cloudy. The sample volume and the amount of DPD #1 and DPD #2 added will produce a pink-to-red color proportional to the amount of free chlorine in the sample. To properly mix the titrant, the test vial should be gently swirled after each drop is added. OTO (ortholtolodine): This has fallen out of favor recently due to its inability to distinguish free chlorine from total chlorine, but it still has advocates. To get a reliable, accurate result, all you need to do is a 1:1 dilution (directions on how to do this are in the yellow-shaded section of the instruction in most of our test kits). The Water Intelligence System that turns your data into powerful operational insights. Taylor's 2000 Series uses printed color standards to achieve a reliable and accurate color match, making frequent test comparisons even easier. If your tests show that the pH needs to be raised or lowered, another test should be done to determine exactly how much adjuster should be added. The FAS-DPD method is accurate for chlorine readings up to about 20 ppm. Again, be aware that a high sanitizer residual (more than 10 ppm for chlorine, 20 ppm for bromine) can create false pH readings. DPD continues to be the standard method of chlorine determination throughout the world. Taylor Technologies kits include everything needed to outfit a facility for testing, and the company's replacement solutions, reagents and indicators make it easy to restock an existing test kit. Copper and iron are the two most likely culprits.
