80 Pieces Water Test Litmus Strips Litmus ph Paper Soil Acidity Meter Liquid pH Tester 1-14 Review

We must look at the color of the wet paper. After drying, the color is lost. Tried on different water (pool, filtered water, tap water) Color is different everywhere Instruction Clear - dipped, looked.

For the purity of the experiment, the paper was dipped in vinegar. That is, it should be densely crimson, the result is in the photo. Absolutely not the way it should have been. I conclude that these are just pieces of paper. . . There is no reaction.

For such a price, you can not demand accurate measurements. So I gave it a high rating. The indicator strips do their job. For a more accurate determination of acidity/alkalinity, something else must be used.

Insights and thoughts on this item.Measurements were made on calibration solutions - if you believe the legend, then the strips lie exactly by one

These pieces of paper do not determine anything, I took the soil on which moss grows (it is sour by definition), the piece of paper did not even stain, it just got wet

Providing an objective assessment.Pros: Compact packaging, enough accuracy for the garden Cons below: I would like to be more precise, but for this money it's ok

by itself, it performs its function, but if you buy it to measure the acidity of store water or tap water, it is useless. in the ranges from 5.5 to 7.5 shows the most similar results, suitable only for measuring very acidic or very alkaline waters.

I am very flattered that the seller is responsible for sending such a seemingly small and inexpensive item. Pros: Litmus paper does its job perfectly! Shelf life - 3 years. A hint on the use of the strips is pasted on the bag, how exactly to use them. Its cons: Unless everything is in Chinese, but the seller pasted a hint in 2022.

I compared according to the readings on test solutions from Tetra, they have an accuracy of up to 0.1. In the first approximation, it seems that it will do to determine the acidity of the soil.

The description says that it is suitable for the pool. actually doesn't fit. conducted an experiment. in the pool shows a neutral environment. leaned against a sour apple, the paper barely turned yellow, completely unsuitable for testing water for domestic needs. by the time when it already shows deviations from the norm, it will be clear to taste! maybe good for chemical experiments. but not suitable for the pool, the description is a hoax.
