So do just put this in a cup, thats it, and then dip pH pen to calibrate? No powders, water, nothing just this?

yes just this. how ever you should also use "PH Calibration Solution (PH 4.01)" to ensure your pH pen is set right.

Mine did not come with a calibration weight. Whether you need a calibration weight, depends on your use for it. I make coffee in the morning with it and measure out the grams of coffee I want as well as the oz of water I need for it. I trust it has been pre calibrated correctly. But then again I'm only making coffee.

First, they have test strips on Amazon for less than $3 that have good reviews and they go below 5.5. I have not used them myself but just ordered some. I use soil and not hydroponics so I'm not sure how to get water to Ph 5.5. They have solutions on Amazon that are specifically made to adjust Ph. And believe it or not human urine can be used to reduce Ph. It sounds ridiculous but it actually works. You just have to experiment with mixing amounts to get to 5.5. And have a bunch of test strips ready so you can test as you add.

Just take stick and dip. Use a cup (Dixie or small solo)-I always wait until I get result before I dump it out. Make sure your don't dip past the max line. If you get the whole stick wet, it won't work at all.

It is not recommended. This is meant to be used as a calibration solution to calibrate pH meters. If you need to adjust the pH up or down, we recommend using a pH Up or Down Adjustment solution.

In order to calibrATE you do need the packets and thew ionized water. Unless you can get a lab to check it against their equipment

I was told by word of mouth that you just dip it into the plant soil when testing then remove it immediately once you get a moisture reading. So sorry that the tip disintegrated :(

You mix it with water the instructions come in the package... It is so many ounces per amount of water

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

Take it out of the package and drink through it like a straw. All your questions have been explained already in the comments section. I suggest you take a moment and read them.

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.

It is in liquid form, but it does not come with any measuring device. Most pharmacies can provide you with a measuring syringe or cup. If you get an oral syringe, be sure to ask for a cap adaptor; it will be easier to use.

There should be a packet of powder that you add to distilled water. Then turn on PH meter, and dip into solution. Hit and hold CAL until it flashes. Then pick the number that is closest to the solution you will be testing (4.0-acidic 7.0alkaline 10.0) then hit ENTER. When it's calibrated it will display END. Repeat once a month to ensure PH meter reads correctly

Have only used the ph strips to test saliva / urine as per box instructions. Don't know how u would test vaginal ph balance

no solution comes with it but amazon has it in 4 7 and 10 the one i got was right on and hasten drifted in 6 weeks just look up ph buffer of calibration solution and a number of them come up hope this helps

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.

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.
