Taylor R-0004-A Ph Indicator Refill .75 ounce

I have always had good luck with the accuracy of Taylor test kits. Every now and then I double check with local pool shop.

If you run a hot tub, you need to be aware of your water's pH. Test strips are too inconsistent and difficult to read. The Taylor reagents work with the Taylor comparator and provide a reliable, consistent, repeatable test. I only maintain my personal hot tub so the 0.75oz 'A' size is perfect for me. These should be thrown out a year after they are opened, even if the expiration date has not passed, according to the manufacturer.

Works like it should, not much else to say about it.

Geeat find replacements for test kit

intended to work with Taylor 2000 series of test kits. I think one drop of R-0004 is equivalent to 5 drops of R-0014 test reagent. I use the R-0004 with my 1000 series test kit, using just one drop to pH test instead of 5 drops of the R-0014 reagent. Test it yourself if you own both reagents.

I intended to order R0014 but inadvertently ordered the R0004 reagent. I researched and found that they are NOT interchangeable due to coloration and water sample size. I planned to place a new order for the correct solution. However....I found a site (and one of the answered questions on here) that suggested using two drops instead of the five. This produces a VERY similar result with the water sample in the 1000 test kits. I'm sure if I was to put it under a microscope there may be a slight variance, but it works well enough that I plan to use the rest of the 0004 bottle in place of buying a new 0014.

Taylor is the only brand I use to keep my pool chemicals balanced. Will purchase again. Pretty fast shipping too.

Easy to use. When I take water samples to my local pool supply store for professional testing, it always matches what I came up with at home. I'm very comfortable with this product

Works as it should
