Can these strips measure the PH of black coffee?

I don't see why not. I just tried it in my coffee (which has creamer though) and it showed a PH of 7...which seems about right since I added creamer and stuff.

If it tests for what you want, then yes. It is necessary to check free chlorine in saltwater chlorinator pools to make sure the saltwater system is doing its job. So these strips will work for that (as well as ph, etc.). But you probably also want to test for salt level which these strips will not do.

No. Each meter uses its own kind of strips. This is only for a True Test meter.

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

Some of these units come with a clip to allow you to attach it to the side of a pot. So long as the probe is not touching the bottom or side of the pot you should get a reliable reading. Just be sure you have stirred the pot so the temp of the liquid is uniform.

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.

Measures Free Chlorine, Combined Chlorine, Bromine, and pH. If pH is off, it will help you determine how much acid or alkaline to use. I like this better than test strips.

Unfortunately they are not compatible with the next meter, you must use the Next strips, Amazon also offers this item in its inventory...

take soil samples to your local extension office and they will give you a full analysis of your soil including ph. Do not use the rapid test strips as they are not even close to accurate.

The outer or end pad tests the ph by testing the concentration of hydrogen ions present, hydrogen ions have a positive charge (H+) and are acidic. The other pad I believe tests the presence of hydroxl ions, they are negative (OH-) and are alkaline. It seems the strips are testing the positive (outer pad) and the negative (inner pad) to get a more accurate results. One pad (outer) tests the H+ while the other tests the OH-. The more H+ the lower the ph and the more OH- the higher the ph. So each pad approaches the test from opposite ends of the scale making them complimentary. One pad sensative to the + ions present and the other sensative to the - ions. The outer pad should be sufficient and the inner one just as a back-up. To really simplify, the outer pad begins at 0 through 14 (0-1-2-3-4-5-6-7-8-9-10-11-12-13-14) and the inner pad begins at 14 through 0 (14-13-12-11-10-9-8-7-6-5-4-3-2-1-0). In the ideal, the outer pad (H+) and the inner pad (OH-) should reflect the corrosponding colors to a certain ph but in the real world they may be off a little. When (H+) and the (OH-) are balanced the ph is 7. The reason we are told to use the outer pad is because testing ph by measuring the hydrogen ions is the most common method but either pad should give the same result.

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.

No. This only tests for ph, ammonia, nitrite, nitrate. You can get a cheap hydrometer here on Amazon. Just do a search for it.

no but i measure my coffee by using a measured scoop and i believe that markings would be hard to read.

Probably not. The levels of chlorine in drinking water should be well below the detection range of the strips. If you can get a reading with these strips for anything other than pH with drinking water, then you have very hard, over chlorinated, questionably safe drinking water...

Yes. It's in a convenient single serve packet. Can use in coffee, tea spaghetti sauce, whatever . Makes black coffee look a little cloudy but no flavor change .

Hi Mike, pH Dips have been designed to indicate whole number values for pH and you should easily be able to estimate 0.5 or half units as colors on the test strip may fall in between two whole numbers. I hope this helps. Thank you for your purchase.

No it does not appear you can. I always use a container of some kind and if say I am measuring loose or wet items I use a disposable paper coffee filter.
