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

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..

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.

It is better to use a well calibrate meter for ph rather than thee solutions.Since color variation is very wide and accompanying card does not match actual water color . One can only judge it is more acidic more alkaline or lesser acidic or lesser alkaline.Just a rough estimate quickly

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

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.

Recieved the package with missing colour chart. I needed it for aquarium pH check i.e. estimation will do the job for me. So didn't face any issue regarding the missing chart. The product works fine. I would recommend it.

It's quality is not accurate

I have used so many other brands, but somehow the Wellon PH test liquid drops are more promising. Totally satisfied, though some say its expensive, but then its the quality that matters. I am very happy using this product.
