About this item:
The test paper should be stored in a dark, dry, and cool environment, and cannot be stored in an acid-alkaline air environment.
Test the properties of the solution: take a small piece of test paper and place it on a watch glass or glass slide, and use a glass rod or plastic dropper with the test liquid to point it on the middle of the test paper, observe the color change, and compare the color with the color chart.
Test the properties of the gas: wet the test paper with distilled water first, stick it to one end of the glass rod, use the glass rod to put the test paper close to the gas, observe the color change, and judge the nature of the gas.
Package Contents:
80 test strips *5
Standard color card *5

5.0 out of 5 stars Simple and accurate
Bought in an emergency as my very expensive PH pen has just packed up and I check the PH of my hydroponic solution every 3 days, as I can not afford a replacement Blue lab just yet I decided to go old school and get litmus paper (does anyone still call it that?) and it does the job.I keep my PH between 5.2 and 6.2 and obviously this paper does not have that degree of accuracy but it at least tells me I am in the right range and not dipping below 5.0 as occurs with nutrient absorbtion over a period of days.I checked the paper with a few liquids such as vinegar, lemon juice and bottled water and it it does give an accurate reading.Only a fiver for 5 packs of strips and each pack is individually sealed in plastic so very good value too.Better than buying one of those useless yellow PH pens for £7.99.Cheap and they do the job.
4.0 out of 5 stars I got this for testing if my grass was laced
It's the closest thing and it didn't do the trick but I'm not saying it's a bad product just not for me, I'm not weeing in a cup to get mugged, make it legal or have health regulations because you can't stop innocent people ♥ I reckon its accurate for the right thing.
5.0 out of 5 stars Good
Really good and lots of strips for the price.
1.0 out of 5 stars Miserable, don’t buy!
This is miserable and defiantly doesn’t work. Tried it on many liquids with different pH. It either stays neutral or turns light orange towards alkalineAcids show alkaline. Nothing could turn it purple/ dark to show acidity. So it’s not only not accurate, but either badly made or expired!And of course you can’t send it back. A total waste and regret. Better off go for another brand. .Unfortunately, there’s no ZERO stars that it deserves, hence, the one star rating.Shame on them.
5.0 out of 5 stars ph water testing kit
Great product
2.0 out of 5 stars The stain more than tell the PH
Not sure if these work or not...what they do do is stain. The dye seems to come off very quickly... so the results are weak/faded and unclear. I've compared them with others and they don't seem to give a very accurate result. If you place them on your tongue it leaves the dye behind... not a great product.
Practical one
Ratespiel
Na ja...ziemlich enttäuscht. Zeigt natürlich was an - aber könnte zwischen 3 Farben passen. Schätzomative. Und Papier tränkt sich ganz. Eher nicht
