One of the pictures has a reading of 18.3. I'm not a scientist,but I'm positive that the highest end of the pH scale is 14. How is this possible?

Yes it is possible for pH to go above 14. It iis also possible to have the pH go below zero into the negative. Most chemicals will fall into the 1-14 range but there have very potent acids and bases that will exceed that generic range.

Youre right, the PH range is 0-14. the picture reads 18.3 because the meter was turned on without being submerged in anything.

I get around 700. The package says 1500. The measure is taken with a solution that I made about a week ago (unused, of course) since I don't trust the result if I measure the solution's ppm right after I mix it since there is a lot of solids that you can see with your bear eyes even two days later. To make matter worse, I do have a PH meter but I did not order the standard solution which would allow me to calibrate it at this precise point. I don't know if the solution will measure to 1,500 once I add more particles lowering or raising the PH.

Sorry. I bought this as a gift for my sister-in-law in another part of the country. I don't know the pH of her soil, but the plant is thriving.

There is no calibration. The button is only to get a reading on the meter but it will give you a true PH reading.

You have to calibrate it. It was beyond me. But i had a friend who'd done well in chemistry. He was unsuccessful in getting a reading that made sense, but I blame that more on him, than the reader. I would look for a pre-calibrated meter for someone with limited tech skills. i needed it to test PH in pond water. I have several mud ponds. The PH is a little different in each of them.

You might want to check whatever meter you're using. I have a digital pH meter that consistently measure the pH of this water over 10.

I noticed the same thing, it reads higher than the bayer one I have also by 20 points. This meter is a piece of junk in my opinion, wastes lots of strips.

For correct cyanuric acid (stabilizer) reading, the ph and alkalinity will need to be within range.

A standard litmus kit cannot accurately test the pH of water due to the chemical traces on the strip and the reaction process.....Seriously? Those chemical traces and the reaction process are EXACTLY how pH is determined. This is like saying a speedometer can not be used to measure speed because it measures distance traveled over time...... /smh

hey. um i would imagine so because its acidic. but i would not know how much more..but what you can do is use the test strips to test the acidity and just add drops until you get the ideal ph. :) hope this helps

It is not listed on the bottle anywhere, so I stuck my pH strip into the bottle. It came up with 6.25pH.

Any. All ph meter should be calibrated once a while with a solution like this. You will find helpful to use the one suits best for your measures. Lets say you have to measure ph levels arround 5. So you get the 5 calibratiom solution. Or you need to measure arround 11, then you get the 11 calibration solution. Or like me, for marine aquarium, that o need to be as acurate around 8, then I use this product. Some meters will require two calibration Solutions, check that too.

Thank you for asking Linda; the pH can be adjusted to a range between 8.5 and 10. Please feel free to call: 970-485-5955 or visit us at WaterForHealthUSA.com Thank you for your interest. Bert Middleton

You should calibrate the meter with both the 7.0 and the 4.0 solution and you can store in the solution closest to the PH you are going for. Hope this helped.

The one I received was pretty close about 0.2 if I remember correctly. It is not really an issue though as it comes with chemicals to mix calibration solutions. You just need to mix it with distilled water.

Be very careful about changing your PH. Do it in little increments . If it's at 7 just leave it at that

Most pens calibrate at 7.0, check your pH meter's instructions for further calibration information
