If distilled water is ph 7.0, why can't I just use that to calibrate ?

I've tested various distilled waters and they vary from 6.xx to over 8.0; YMMV. Calibration solutions and powders are cheap and long-lived.

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.

Yes. Use RO or drinking water and run threw zero water filter. PH up to 7.4 using ph meter to verify.

As Mark said NO, it is fixed at C. However, I only use the temperature readings to make sure my calibration solution and my rinsing solution are at the same temp. Speeds up calibration. You have to press the C button to get the reading and as soon as you let go it goes back to pH. My cell phone has a C to F conversion when necessary.

hey. um i would imagine so because its acidic. but i would not know how much more..but what you can do is use the test strips to test the acidity and just add drops until you get the ideal ph. :) hope this helps

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

FROM HM DIGITAL: The accuracy of the PH-80 is + / - 2%. It is factory calibrated to pH 7.0. The meter can be easily re-calibrated with digital calibration to pH 4.0, 7.0 or 10.0. All pH meters should be calibrated anywhere from before every use to at least once a month. The frequency of calibration depends on usage and application, but you should calibrate at least once per month for proper results and a longer lifespan of your meter. A free packet of pH 7.0 buffer is included with the meter. Additional pH buffers for calibration are available for purchase. For more information, please visit www.tdsmeter.com/products/ph80.html

The only calibration I have seen happens during each power-on. The directions ask for a vial of clear pool water and it self calibrates.

You make a slurry of equal parts screened soil and distilled water. Then you train the slurry and use the pH meter to read the pH of the filtered liquid. That is the pH of the soil sample. Simple, eh?

As response to the question - you should add it to the water change water cuz if you add it to the already 7.0 water it will make it higher have a great day

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.

Off the top of my head I think it needed a 1:1 ratio with water (1 part G12 to 1 part water). Its best to use denatured or distilled water for best results.

i use distilled water then run the water through a de-ionization process.... expedites the process and if you use a TDS meter during the process you can verify the "potency" of your CS and be uniform in its production.

I am not really sure how it relates to distilled water. I would rather have a whole house filter, but that is not an option right now. I have a PUR pitcher, and the Zero pitcher, so I filter my water twice. Than I put a few drops of lemon juice to make it alkaline to drink. So, I just don't know the answer to your question.. Sorry.

If by "calibrate" you mean manually set the thermometer to a specific temperature, then the answer is "no". On the other hand, if you mean by "calibrate" to check out against a preset temperature, then "yes" you could do this..e.g., immersing the probe in an ice bath.

Ph solution 10.01-7.01-4.01 depending on What ur doing most ppl just get the one I use 4.01-7.01 n calibrate once a month or so and I store in storage solution to keep em on da ball
