What is the range and increments tested on the ph?

6 to 7.6. The increments are .2 as follows: 6.0, 6.4, 6.6, 6.8, 7.0, 7.2, 7.6 My kit was accurate and up to date.

Total range is from 5.0 to 9.0 in increments of 1.0Standard method of comparing color of tested water to colors on a chart so you interpolate in between to some extent

You can test pH of a soil, but not by sticking the probe in the sample. Do do so, you'll need to put a sample of the soil in some distilled water (RO would do) to form a suspension (try not to make it thick or else the pH meter will not read effectively). The more you shake the suspension prior to reading, the more accurate your results will turn out.

The bottle says that the color code is light bluish for 8.5 and higer, so you probably wont be able to accuratly tell what the ph is if it higher. If your just testing regular things like your gardens water you will almost never get any reading that are higher than 8 or lower than 4 (or atleast i would hope so). Hope it helps a little!

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.

This meter's pH scale doesn't vary much above and below 7.0. Most people have a liquid available at the store they can use to do a quick check, distilled water, which under ideal conditions should have a pH of 7. If the scale is off by even a factor of .5, it could really hurt your plants.Some basic chemistry calculations: Kw = [H+][OH-] = 1x10^-14 at 25°Cfor pure water [H+] = [OH-] = 1x10-7Acidic Solution: [H+] > 1x10-7pH = log10[H+]Basic Solution: [H+] < 1x10-7When calculating pH, remember that [] refers to molarity, M.

Depends,A year or so maybe.I would test the PH with another testing kit from time to time.

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

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

PH up and pH down if you really want to but I only use this test kit. Remenber cycling a large tank can take up to 8weeks. Be very patient and test daily while cycling.

Hi Carla, Not sure if this is what you want. I bought it for testing the ph in our club kitchen dishes rinse water. Turns out this is the right one. 2 places to check for the right kind: local health department (they set me straight) and county extension agency. good luck

I have one and it depends on the filter. I have tested the ph on different levels of flow in the water spout and always had a 9.5 ph except when the filter is on the end of life cycle. I have a city water supply. then it came down to 7.5 or 8.0

pH on this meter is 0-8. no calibration needed, just cleaning with pad before use.

I don't know the ph, and the product is better than other brand of victamin c, recommded to try on sensitive skin and problem skin, have a try, I am still continues using these range for more than 2 years. Good to try��

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

FROM HM DIGITAL: The PH-80 is a reliable pH meter that is ideal for testing applications such as hydroponics & gardening, pools & spas, aquariums & reef tanks, water ionizers, drinking water as well as other liquids. It should NOT be used for testing distilled water or acids, as they may damage the sensor. It should NOT be used to test solids. For more information, please visit www.tdsmeter.com/products/ph80.html

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.

I don't calibrate the meter. It works right out of the box for humidity level. I do not use the ph meter or the light meter. May be you can stick in in vinegar and see if it reads about 3
