As this meter is not temperature compensated, does anyone know how much temperature differences will affect the ph readout?

Yes, a 40 degree rise in temperature will lower the Ph by about 0.1 which is not very much. Going from 10 degree C to 50 degrees C reflects as the following. Ph 6.92 down to 6.82. I've used this meter at room temp and 101 degrees F in my hot tub with little difference.

I don't understand why this questions is under the Q and A for the ATC(automatic temp compensation) version of this meter ph-2011, but when I click on the question to answer it, it goes to the ph-009 page, which doesnt have this, this is going to mislead ppl who don't take the time to look up what ATC means when browsing the ph-2011 version... o well

The device is calibrated at 72 degrees, for my purposes I use water at this temp to avoid errors.

The test strip you are using is not accurate/sterile enough to accurately test the PH of water...One thing that everyone should know about these (and other) pH test strips is that they work based on the TDS (total dissolved solids) that are present in the water you are testing. If you are trying to test a true distilled water (with nothing in it, no TDS) the strips won't be effective and I'd recommend you use a test drop for the water sample.

I have not had any issues, but the DW(Distilled Water) I use reads in the 0 to 9µS range- which would show 0 on the mS range.

I found the salt strips to be a bit tricky (compared to chlorine etc chemical strips). They take a long time to read, so I was just laying the strip in the water sample. You need to stand the strip up in the container so the bottom is in the water and let it sit. The strip was reading far lower than it should have when laying in the water vs standing up in the water. Perhaps you are having the same issue and it really is higher than 2000ppm. I started out with too much salt because of this as well.

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).

what parameters does it actually measure ??? does it measure ph and ppm or is it just a moisture and light sensor?
748988
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.

Mine takes up to 15 minutes. That's with a solution with a ppm of roughly 400. It does settle very quickly in a calibration solution, which has a much higher ppm. I understand why there would be a difference, but 400 ppm does seem like enough for a quicker reading.

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

Stated battery voltage is unimportant. Tester measures specific gravity of sulphuric acid/water mix in flooded-electrolyte, lead-acid batteries. If you can safely get to the electrolyte in each cell, you can make your measurements. This tester does not have a thermometer attached for temperature compensation calculation. You will obtain higher confidence in the accuracy of your measurements if electrolyte temperature is at or very near 68 degrees F. Cheers!

Great name! Thanks for the question. The ph range is from 6.0-10(in the red) - end padThis test kit is nice and easy, tests for Bacteria, lead, pesticide, nitrates and PH. I have been testing evrey 2-3 months since I am in PA along the fracking belt and recently my township has converted to Philadelphia public water, no more well water. All the best!

The humidity reading on my old unit that eventually failed got funky and was reading about 30 percent lower than what it should have been. But the replacement unit I bought over a year ago has been right on the money so far. What's weird, however, is that the humidity reading INDOORS on my MAIN unit has gone bonkers now and is reading about 20 percent less than it should be. So go figure. But I have a digit-readout humidifier that I use in the winter, so that's not as important to me as the temperature.

I have a pH meter that I use for wine making. It has a resolution of 0.01 pH, and an accuracy of +/- 0.01. I calibrate it before every use so I am confident of the reading. The pH of the water form the pitcher when new was just over 9 - about 9.03. After 4 months of use with the same filter is is now reading about 8.79. We use two to three pitchers of water per day.

pH of a solution increases with temperature, but only slightly. For accurate reading, temp.compensation unit is better i.e more reliable. But, for most household work, this change is not significant.

We have this test meter for our community well. We fluorinate according to the EPA guidelines. It works well when it is calibrated. You have to have the 1% fluoride solution and the tabs to calibrate the meter. We had the meter for about 4 months and the sensor went bad. The company replaced it immediately at no cost but with the wrong part. It took several weeks to replace it with the right part. It was on B/O for some time. Now that we use it daily I can get an idea of the level we need to be at. It's a field test and they are not 100% but close enough for what we need. When our levels were low the meter just gave a Lo code. It am not confident it would give you a zero reading you may be looking for.

It does not need calibration but you must let it stay in soil undisturbed for minimum of 5 minutes until it displays final PH reading and the PH range is less than 5 and above 7

Certainly. It will read the surrounding temperature -- in air, in water, in bread or wherever else. The one I have is quite accurate. It reads 212 degrees F in boiling distilled water at about a sea level elevation.
