What is the range of pH tested?

They have a low range test that tests from 6.0-7.6 and a high range test that tests from 7.4-8.8 both are included in the master test kit

low ph range from 6.0 to 7.6 and the high ph is from 7.4 to 8.8. most ideal range is 6.8 to 7.8, i think. that is usually the range for most fish. Hope this helps you. :)

Low range is 6-7.6 and high range is 7.4-8.8. I don't know anything about the high range's accuracy, but the low range is ridiculously wrong. I checked it against my calibrated pH meter as well as lab standard known pH buffer solutions and it wasn't even close. I don't know how they can sell it.

Meter is for dissolved solids, salts & temperature. Suggest looking for pHydrion (brand) test strips, which come in broad (pH 0 - 14) or narrower bands. Easy to use. Tear-off paper roll cheaper if just general pH is needed (like a fish tank).

Try to keep your alkalinity around 90-100. I adjust that with sodium bicarbonate. Keep the pH around 7.2 to 7.4. Keep the chlorine around 3 ppm. Be careful on the calcium hardness the drops go bad fast and Won't give you an accurate reading So replace those once a year probably all of them once a year. Keep your calcium hardness around 200to 300 ppm. If you've added calcium to the pool but you can't get the numbers up suspect that the drops are bad. I love the test I use one at home and one of the apartment complex that I own. JR

The other answers are correct, normal biological pH is (neutral) 7; moreover, it is a specific range from 7.35 - 7.45. The human body employs bicarbonate to buffer the blood pH and maintain this narrow range. Saliva and Urine may vary more significantly. Urine is typically more acidic in the morning from pH of 6.5 - 7.0 and gradually more alkaline through the day to normal range of pH 7.5 - 8.0 in the evening. Saliva (human) has a normal pH range from 6.5 - 7.5.

if you had a way to check calibrations at that range it would work for a while. A more resistant coating is formed above pH 10.5.

I don't think this product is laboratory-grade. I would not use this on anything but food products. I would also avoid very high or very low pH.

I don't measure my own pH, I just measured how these drops affected different kinds of water. Three drops generally improved 16oz of water by 2-3 pH. As for my own pH, I just kind of know how I feel through my joints, energy, etc.

Looking at were the ingredients are at, I would say around 3%. There isn't much in it at all, and I would be curious to see what the ph of this is.

The TDS meter checks for dissolved ionic solids. Charge matter little. Positive or negative pH would give similar results. ie a pH of 9 would probably yield a similar TDS value as a pH of 5.

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.

Within 15 to 30 seconds. I've owned 2 different PH meters and I was impressed on how more quickly this one took the readings. I use mine for checking PH in wine, so I'm not sure how quickly it works with other solutions. PH for wine ranges between 3 and 4.

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

FROM HM DIGITAL: The PH-200 is an ideal, waterproof pH meter 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 also should NOT be used to test solids, including soil.

No: range starts at 6.2-6.5. Get a ph meter, I did and works great. About $20 bucks on Amazon

FROM HM DIGITAL: The COM-100 is NOT a pH meter. It measures EC (electrical conductivity), TDS (total dissolved solids) and temperature. For pH, please purchase HM Digital's PH-200. For more information, please visit www.tdsmeter.com

*Moisture readings register on a scale of 0 (dry) to 10 (wet), light readings range from 0 (dark) to 2000 (light), and pH readings between pH 3.5(acidic) and pH 8 (alkaline) are represented.

I would imagine not to much since your ph is already 5.5. its intended to get water probably to around a 6 or 7 but 5-7 is about the normal range. i haven't actually tested my ph with this device before and after so i couldnt tell you to be exact.
