I recently tried BluPure pH Test Strips.
These strips test pH levels between 4.5 and 9, and while they are marketed for saliva and urine to test how alkaline or acidic your body is, they also work for other liquids such as drinking water, pools, aquariums or even beauty products.
I found when compared to other pH strips I had on hand, these were accurate, and fun to use when testing your own body's pH level.
You can find this product on Amazon.
