DIGITAL PH METER CALIBRATION

[uwekackstaetter]

Unfortunately the calibration procedure as shown in this video is WRONG! This is why so many people in the comments have problems with correct readings. Yes, you hold the calibration button down for 5 seconds as indicated in the video. Then the calibration pH will show (e.g. 6.86) BUT YOU WILL NEED TO LEAVE THE PH METER IN THE SOLUTION UNTIL CALIBRATION IS The calibration for the pH point is completed once the display stops flashing and goes to solid. This may take several seconds! NOW IT IS CALIBRATED. Taking the pH meter out right away and looking at the display as shown in the video will NOT, I repeat, will NOT calibrate the instrument. You must leave the instrument in with the displayed pH until the flashing stops. You can simply retest by now inserting the instrument into the solution without the CAL button being pressed. It should show the pH of the solution as indicated. If you calibrate with only the 6.86 solution your readings will be accurate to 0.1pH. For accuracy to 0.01pH you will need to calibrate using ALL 3 solutions. This is called a 3 point calibration.

Thank you! I bought two of these, neither one told you to quick press calibrate once or twice more. You’re the best!

Thank you for sharing, I tried calibrating but failed dismally as I didn't know about the fast press. This really helped me alot. Thank you for sharing.

0:50 I can’t imagine where you got this idea but that’s not a glass vial full of water in the tip and the cap doesn’t keep anything from drying out. The piece of glass in there is just an insulator for the small sensor inside it and the cap is to keep it clean and protect from scratches.

Hey don’t know if you’ still do videos but this helped me today ...this is my second time buying the buffer solution to calibrate it because I messed it up the first time lol

[johnconstantine]

THANK YOU, this video was alot of help.Jesus christ bless you and family.

omg lifesaver! i'm just here trying to figure out the instructions for my new pH meter and saw your video. The stars must have aligned 🤣because you have the exact same one as me with the 3 buffer powders. thankyou so much! it was doing my head in lol

[coolrn]

Should have watched this before I totally screwed up my calibration! The directions in the box were crap!

[tomfile]

Thank you. The cal instructions with these cheap ph meters leave a lot to be desired.

Best vido in internet of ph calibration, by far.. thank you :)

[jonnyblazedemall]

Thank you! The instruction manual is not as clear as your tutorial! I really appreciate you!!!☮️💚🧬

This totally helped me. I m currently doing experiment on pH kf fermented rice and hoping all turns out well! Thx 4 sharing !

Thank God! Somebody I understand. Thank you. I did see Uwe Kackstaetter's post about not removing the meter until the flashing stops. Otherwise it won't calibrate. For cannabis grow can't I just use the one needed packet verses all 3 packets. I still don't understand it all. I'm determined though. :)

Thank you very much, it has been very useful to calibrate the equipment.

[tashanewman]

Thank you ma'am. Used your method and it worked.

Nicely explained. Thank you for the detailed information. (From India)

Well done! Always help to have a visual! Just received mine to test spa water. Also, mine was German made (live in Germany) and the written instructions have me using the ph 4.0, then 6.86, then 9.18. However the diagram part of the instructions have the 6.86 first like you, so that’s what I’m going with!
Thx again!

TO EVERYONE SAYING THIS IS WRONG ->. It is NOT wrong, shes just doing it differently. I know because ive tried both ways 1000 different times. When you quick press like she is, you dont have to leave it in the solution like that.
"Quick press" takes you directly to the different ph buffers faster without having to hold and wait.

How do i know this? I HAVE AN IN-GROUND FRICKIN POOL and a Jacuzzi 6 person Spa....going on 15 years now. I check the ph every 3 days, 365 days/year. Calibrated every 2 weeks. Believe me, if the ph were wrong in my pool it will turn the water either brown or cloudy dark green.

Thanks for just making a simple video and not overcomplicating everything c:

Thanks for the terrific video. Great information!
