Technologies R-0004 pH Indicator Reagent, 2 Ounce

Taylor. The best water testing available. Easy to use.

It’s the larger bottle (not the small one that fits in the blue kit) and it’s perfect. It lasts a long time with weekly testing. Way better price than at the hot tub stores and it delivered super quick. Will buy again.

I am the 4th reviewer to have recently received a 0.75 oz bottle even though the product description clearly states that the product offered is a 2 oz bottle including a photo of a clearly identified 2 oz bottle. I have returned the product to Amazon for a refund. I would like to write it off as a mistake, but the fact that at least 3 others have received the small bottles makes me suspect that it is more than a mistake.

The bottle arrived in good condition and yields the same results as my other brand PH reagent. Phenol comes in different concentrations. With this Taylor R-0004, I use 2 drops for my color match. Some brands need 5 drops to get useable readings. With my test kit, 2 drops gives me the same reults as my original reagent and my test strips. Save money with this 2 oz. size.

Did well
