Enhance Organization with INHDBOX Universal Plastic Strips Strips: A Practical Storage Solution Review

Each week we use hundreds of pH test strips to test the pH of incoming water samples. The problem reported by our laboratory technicians is that the indicator dyes "bleed” when wet, making the pH value assessment of the water sample difficult and unstable. After trying these strips we will continue to use our regular brand of pH strips. We were looking for a cheaper alternative but no less quality product.

Colors don't really change from wet to dry unless other colors shimmer when wet. I've tested with high and low pH and the color doesn't change much and sometimes it doesn't even match the colors on the pH chart, some get lighter and darker and you can't find any color. burned my plants due to inaccurate readings, I ended up buying an $80 Hannah pH tester at a local store who calibrated it for me and have had no problems since.

Color goes into the test liquid almost immediately, especially blue. If you leave the strip in a glass of water for more than 2 seconds, the water will turn a distinct blue color. Also, more importantly, I tested accuracy with a newly certified Mettler Toledo pH meter and these strips almost all showed low readings. The strip clearly read pH 7 while my meter read 8.2. These strips are completely useless. You might as well try to imagine what pH is instead of measuring it with this product. This
