Wellon Ph Drop for Ph Testing, Ph liquid Water Testing with Ph Color Chart(5 ml)

Product is good and does work though I am not sure whether the color/chart is perfect or not. It showed the PO value of RO purified water as 5.5 (not sure correct or not). But for different liquids it showed different colors indicating it is working fine. Satisfied with this.

I bought this to check the water at my house, and it was a real eye-opener. It was super easy to use - just a few drops, and I could tell immediately that my drinking water was acidic. Thanks to this simple test, I was able to fix the issue. It's a really helpful product and I'm glad I bought it.

Bought to test tap and Ro UV filter water... Initially the color was greenish blue in any kind of water we tested in mumbai. My mom kept saying that it is jusy a bottle of food coloring. However when we tested the water of bore well and tap water in my home town , the results were different. The water was dark blue , hence giving different result for different specimen. worked well! Quantity is less but for small specimen it is more than enough.. if you are looking for professional use , please go for something else..

good but very expensive and very low quantity

This product is very nice with perfect colour change even i say that it is accurate.. But the only problem is that it is very small even that smaller than you think

Working fine and the guideline provided with it regarding colour and ph correlation is accurate. Only two or three drops to be applied in 30 ml of water which gives result instantly by colour changing.Then the colour of the mixtire should be compared with the provided chart to get the value of ph for the specific colour of the mixture. One thing I must admit that the solution is over priced compared to its quantity.

At first It seems all water are same. But using accurately with right amount of drop and water it give you right result. I'm using it to test Ph level of my Aquarium and drinking water. Neon terta and betta fish need little acidic water or low pH 6.5. I needed a good ph test kit. Thanks a lot

It's quality is not accurate
