Simplex Health Paper Water pH Test Strips 0-14 Wide Range. High Range Duel Pad for Acid Alkaline Testing (100 Strips)

This pH paper really came in handy. I used it to make home made shampoo and the strips were accurate for what I needed and quick in results. They are multi function and a good item to have around. I liked the little box it came in. Very tidy and easy to store away.

Good product

all ok

Not sure how accurate these are but as far as finding out whether you are low, medium or high in acid, they're very good. I tested one with saliva and one with urine, both gave the same reading. Came up between 4-5, which suggests I am high in acid. Then I drank half a pint of water with half a tea spoon of bicarbonate of soda. Waited 2 hours tested again and came up with 6-7. Drank the same quantity again and several hours later I was between 7-8, low I'm acid. I will prepeat the same process over the course of a week and take note and edit this review. First day felt much more energetic (got a lot done) and mentally felt positive :)

The colours run in to each other but that's all the colour change you will get...I even tested them on bleach just to be sure!! AVOID!!!

Simple to use, very cheap.

Did the job and give you a pretty good idea of the pH of the test solution. My main criticism is that the colours bled quite badly so you need to be quick off the mark to assess the reading. It was claimed that the colours would not bleed so I was a bit disappointed with that aspect.

Fast delivery perfect

Per essere delle cartine tornasole e non un misuratore digitale, fornisce dei risultati del ph molto vicini alla realtà, l errore è inferiore a 0,5, ottime.

Petites bandelettes tests PH bien pratiques pour déterminer le PH d’un liquide rapidement. (Les acharnés des valeurs PH au dixième, orientez vous vers un PHmètre numérique !) Testées sur solution d’acide chlorhydrique et solution d’hydroxyde de sodium. Réaction rapide (moins de 30 secondes), PH correspondants, lecture des résultats aisée. Petit bémol, sans grande importance selon moi, les pads colorés ont tendance à baver un peu.

Ok

Works well but when compared to another test strip it appears there is a .5 difference. Can't be sure which is more accurate.

Ein PH-Test der ein recht genaues und gutes Ergebnis anzeigt bzw. gut funktioniert! Preis-Leistung, sprich die Qualität ist daher völlig in Ordnung und nicht überzogen teuer. Nach 2 Jahren in der Verwendung sind wir nach wie vor von diesen Tests sehr überzeugt und geben deshalb eine klare Kaufempfehlung ab! Daumen hoch....! :-)
