Jovitec Universal Ph Test Paper Strips Ph Test Strips Roll, Measure Full Range 0-14 Each 16.4 Ft(2 Rolls)

These work very well. In the photo you see the results of a control test, on the left the results of a vinegar (acid) solution and on the right a baking soda (alkaline) solution. The colour of the strips clearly indicates accurate pH measurement against the provided reference. I used these for a soil test to determine adding lime to tomatoe potting mix. They displayed a neutral result tested with the soil which looked the same colour as the testing paper but just wet. I think this result is why some people think it doesn't work. Would recommend over the cheaper options found on amazon. Shipped quickly, accurately and in good condition. Will buy again.

The Jovitec universal pH test paper strip roll offers incredible value for anyone needing to measure pH levels.

Gout patients frequently have acidic urine, which increases the risk of kidney damage and the formation of uric acid stones.***

So I’ve created my plant feed for my Peace Lily; using the leaves that eventually die off (as they do after so long each) So cutting the leaves & stems into tiny pieces; putting into a jar with plant feed pellets & tap water (and adding new dead leaves as & when) All in all my homemade plant feed is to reuse the last nutrients etc in the leaves That said I didn’t want to poison my plant with this experimental homemade plant feed mix (Such as due to the fluoride in tap water etc) So bought these strips to ensure my homemade plant feed is neutral on the ph scale It registered as an 8 (1 above neutral 7) so overall happy (would probably use distilled water in my next feed batch etc instead of tap water) That’s the reasoning for these ph strips Thank you

Dispenser is useful and compact, came in resealable bag to keep dry.

The colours on the wheel are not particularly specific, going in increments of 1, so if you need to be precise in the pH reading these are not for you. Also, even when putting the strip next to the wheel to compare the colours it's still hard to tell if it's one or the other. If what you need is an estimate of the pH these will do fine, if you need to know a precise number, look somewhere else

This is a cheaper and effective way of ph balancing your water/nutrients mixture . I’m using it for feeding potted plants and am experimenting with ph at the required level as per plant . I am seeing a marked difference in foliage and flowers . So I would say this paper tester works well

Very simple and accurate way to test Ph of a liquid. Coloured coded chart indicates scale of acidity and alkalinity.

Great time. Doe what it says. Paper turns the colour just a few seconds after, according to the PH scale. I like that it is in a roll, can rip as little or much as you like. One roll will last a long time. I use it to measure PH water of drinking water from a machine.

I just tested vinegar which turned Red with 1pH. Saliva was green 7pH and urine was gold = 5pH. So I have no idea why people are complaining about the strips not changing color. They seem like a quality product, easy to use and easy to read. Just don't ever expose the strips to any humidity or moisture. Do not store the strips in an area that will be exposed to steam or humidity which will ruin the strips. And use very dry hands and surface when handling these strips. Moisture will render them useless. If you're a novice and using these strips to test kombucha, use a small container to collect and test the booch. Dipping the strip into the fermentation container will ruin your batch as there are chemicals that will kill your Scoby. Anyway buy these with confidence and keep them bone dry.

perfetto per le attività laboratoriali casalinghe o scolastiche

Je m'en sers pour contrôler la préparation d' EM-A (microorganismes efficaces) , la précision est bien suffisante et plus fiable qu'un PH mètre BAS DE GAMME a moins de quelques centaines de € ou $, qu'il faut en permanence étalonner avec des "sauces" plus ou moins précises . j’étais chimiste, 34 ans en recherche, habitué à me servir de colorants ou de papiers ph pour les contrôles rapides. Pour les "ceuses" qui ne le savent pas, on ne trempe pas la bandelette dans la solution mais on en prélève une à deux gouttes que l'on place sur un petit morceau de bandelette PH. Un PH mètre fiable ça vaux une fortune et çà s’utilise en labo dans des conditions bien précises, mais pas devant le robinet ou la piscine !!. L'expérience en chimie ou en physique ne s’acquiert certainement pas dans les forums et autres YOUmachins. Avant de formuler de mauvaises critiques apprenez (pour certains) à vous en servir.

Quería hacer una prueba de ph en un pequeño trozo de tierra donde tengo plantados 18 tomateras, con problemas de podredumbre en su base. Bien, la prueba salió satisfactoria, la tierra tiene el ph correcto, ahora tengo que buscar por otro lado.

good price , & what I ordered
