Here's what I get. Typically you want to achieve a slow drop rate of about 1 droplet per sec where the droplet forms on the tip and falls off under the forces of gravity (not you wiggling it). 
Something went wrong. 
And I will have a look at your mannitol procedure. 
Fluid viscosity, finger pressure, back-pressure inside the bottle, static electricity, etc, can all affect the droplet volume. The 50 ml beaker is another matter, it has been shipped twice by Amazon and arrived crushed both times.

Thanks for continuing the dialog with me. Thanks very much. The test pads have a pH indicator dye and a prescribed amount of dry acid and buffering chemicals in them. Wont work because the addition of MA is decreasing the carbonate portion of the TA. Use tab to navigate through the menu items. Im having a laugh at myself. And its mainly the difference between the two readings that matters. Pool and Hot Tub Depot and the Pool and Hot Tub Depot logo are registered trademarks. You could always give it a try and see what you come up with. Seller assumes all responsibility for this listing. It's complicated in the details but that about the best you can achieve with a low-tech dropper bottle. We are a registered 501(c)3 non-profit that is funded by user donations. As I said, I've got all the chemicals on order for a better test. In most cases the test strip will be enough in determining the range of the chemistry in the pool or spa but again you will not be able to tell if it a pH of 7.0, 7.1, 7.2, 7.3 or 7.4. They are easy to use, coinvent and inexpensive. I also went back and read several more pages in the test instruction thread.

Test strips are a great way to get a snap shot of your pool or spa chemistry levels. The reason is simple: TFPC (Trouble Free Pool Care) is a methodology, not a product that you must purchase. Again, Pool Math is just not that accurate. You must log in or register to reply here. The levels indicated by color are pretty hard to determine and fairly widely spaced: 0 15, 30, 50 and 80. You will not be getting an exact reading with test strips but a range.
I looked up the specs of a medium quality meter (~$300) which has a resolution of 0.01 pH units and a published accuracy from the manufacturer of +/- 0.02 pH units @ 25degC. some variations of shades and the user will need to decide which color matches closest. Also note that when using test strips in general the color matching will not be exact at every reading. If you have a. pool the Taylor Salt Test Strips would be a good way to verify the salt level in your pool. Test strips can also test for things that reagent or photometer testers cant test for like the salt level and borate levels. Copyright 1995-2022 eBay Inc. All Rights Reserved. They are easy to use, coinvent and inexpensive. The problem with the test strips is that the reaction is not that strong and color change is hard to detect. You will know it is between 7.0 and 7.4 which is fine if you are adjusting the pH up or down in your pool or spa. If that is the case, then dispensing something on the order of 10 to 20 drops or so should have the effect of cancelling out drop-to-drop volume variations. I finally received the BTB, and Mannitol. deals news & more, Get the latest updates on new products and upcoming sales. Then dip the strip in the water sample for the time indicated on the bottle and hold it flat without shaking the excess water off. Then wait the recommended time indicated on the bottle and match the color with the color chart on the back. If you want to verify the test strip reading a reagent test kit would be a good investment. By selecting whether I use 1, 2 or 3 drops I can control the size of the difference1 drop gives the smallest delta. You will not be getting an exact reading with test strips but a range. This means that there. If you have a salt water pool the Taylor Salt Test Strips would be a good way to verify the salt level in your pool. So, if you need an exact reading of a test factor you can use a digital tester or a photometer tester. Testing the water in your pool or hot tub regularly with a Taylor test kit or AquaChek 4 in 1 test strips gives you the information needed to keep and or adjust the the Alkalinity, pH and sanitizer levels to maintain clean sparkling clear water. If borates are present, the buffer/indicator reaction is slightly changed as is the ultimate pH reached.

I just use 50mL because the math is easy. When using the Taylor test strips it is highly recommended that you use a water sample bottle and get the sample 18 inches down in the water away from a return jet to get the most accurate reading. The Taylor titrating bottle fitments are supposed to be designed to yield 40 uL/drop (25 drops = 1mL). I have a tube of the Insta-Test Borate test strips that I've been using for a year. It sounds like with any titration test, you want enough drops to avoid drop to drop variation and not so many drops that you add other errors. This means that there is some variations of shades and the user will need to decide which color matches closest. I didnt mean that the MA would actually be added to the pool!

Excessive droplets counts can lead to long term systematic errors in volume. The color will tend to drift over time so it may not be that helpful. If the color shifts over the 2-3 minutes it takes for the final steps then it wouldn't be of much value. If you read through the entire thread, I think Richard outlines other volumes you can use. the test strip will be enough in determining the range of the chemistry in the pool or spa but again you will not be able to tell if it a pH of 7.0, 7.1, 7.2, 7.3 or 7.4.
