Hicarer 400 Strips Plastic pH Test Strips, Universal pH 0-14

These work great. With the 4 different colored squares, I am more confident that I have an accurate Ph level than with the single colored paper strips. The 4 squares are secured onto a longer plastic strip making it easy to measure readings without getting solution on yourself. I found the price reasonable. I do go through a lot of these, I measure the ph level before generating my solution, again if I make any adjustments, after generating it, and before using if the solution has sat a while. You can cut these vertically in half or 3rds to stretch them. I find the current price point very reasonable, and plan on making these a regular purchase.

Helps see between whole numbers.

Good price. Works well.
