The color does NOT match the label. Tap water is testing green blue and filter water is blue. Doesn't match label???

Hi, Elsie. The color results that you are getting are an approximation of what your water sample's pH is. For instance, if your tap tested greenish-bluish it could be that your tap water is in the 7+ pH range. If your filter water tested blue, it could have a pH of 8 and above. The results that you are getting may also be influenced by other factors such as the source water of your area, condition of your machine, and the pH setting that your machine was at when you took the water sample.

Is this good for testing the pH of shampoos and conditioners

No..reccomend for clear liquid..u can try and see

can this be used to test if paper is acid free?

There is a pen you can purchase at a stationary shop. It will let you test for acidity or alkalinity.

is there an expiration date on this product where it will not give accurate results? I've tried both liquid & strips & got different results.

Not sure. But there are tiny print numbers at the bottom of the bottle .It may quite be the expiration date. But one definitely need a magnifying lens to visualize it. Hope that help!

Surprisingly Accurate

This was a straightforward easy to use liquid ph tester. Because I knew going in that one water I was testing had the pH on the bottle, and I knew my town municipality water pH, I was able to guage if this was correct. To my delight this product was on point! I used the pH's that I knew as a gauge as to if this would perform well. It did. Glad I bought it, as I'm trying to get healthy and drink more alkaline water.
