Buying Guide for pH Test Strips

Why buy pH test strips?

Fluids and solids from saliva to soil to drinking water contain chemicals, bacteria, and varying pH levels. All of the substances have their ideal balance. Plants like blueberries prefer more acidic soil, but the human body functions best at 7.35 to 7.45 pH. How will you ever know the pH levels of anything important to you without pH test strips? You can send samples to a lab, but that quickly gets expensive.

What should you look for in pH test strips?

  • Range: The pH range that a pH test strip can measure is significant. A smaller range may lead to more accurate results that are easier to read, but you will not be able to use these for substances with a pH that falls outside the test strip’s range. Standard ranges are 0 to 14 with accuracy within 0.25 pH. Soil tests range from 3.5 to 9. For most substances, the greater the pH range tested, the better. 
  • Target Sample: Aside from the science class pH strips, most products target a specific sample or substance. If you want an accurate reading of the pH balance of your vegetable garden before you plant, look for a product made for soil testing. The same holds true for drinking water. It’s great to get an accurate pH reading of your drinking water, but you need a lot more information about possible contaminants. In that case, look for pH strips designed for drinking water.
  • Contents: If you’re running a high school science lab, buying in bulk is the way to go. On the other hand, you’ll want both testing strips and bacteria tests if testing your drinking water is your priority. Other things to look for include instructions, colorfully illustrated charts, and guidebooks.

What should you do if the pH levels are off?

If you’re testing the alkaline and acid levels of your urine or saliva for health reasons and the readings are out of the healthy range, you may want to see a doctor for guidance. If your gardening soil is more or less acidic than ideal, you’d probably be better off consulting with a landscaper or professional gardener.
