FIX IT!!!...How To Fix Your Cheap PH Meter

[@flexiblebirdchannel]

Yes, these pH probes dry out if stored in their cover, so soak before use for 24h preferably in 3m KCl solution but tap water will do also as stated in the manual. The problem is the calibration, it does not work as mentioned in the manual. The meter will adjust to 4.01 if stored in anything that gives a readout below 6.5 and cal is pressed longer than 3s, will calibrate to 6.86 if stored in anything that gives a readout between 6.5 and 7.5 and to 9.18 if stored in anything that gives a readout above 7.5, so the region where it goes to 6.86 is very narrow. And it takes some time to stabilize, give it a minute in buffer solution. By removing the battery, it resets jammed calibration. The extensive cleaning is usually not neccessary, only milk should be cleaned with pepsine. The problem I have is the 6.86 buffer solution, that gives 6.65 if tested with a professional calibrated probe, so the reading of this cheap probe is approx. 0.3 too high, but the buffer solution is packed by the dealer, not the manufacturer. But the technical quality of the cheap probe is nothing to complain about, it's the one tap software for calibration.

I don't think disrltilled water should read zero.... that's a steel dissolving acid. 7 ish would be preferable but electrically measuring ph on distilled water is not accurate.

You forgot the blowtorch🔥

[@Khryz-mc9nv]

I accidentally drop it in the solution and it's not turning on😩but this is a nice video👍

[@trupyrodice4462]

Just open it up -take the batteries out and put all pieces into a bag of rice overnight, or until dry. Check to make sure it’s all dry inside and replace the batteries. You’ll be up and testing your sugar washes, fish tanks, or like, you know… your methamphetamines or whatever. Lol. I dropped mine into my sugar wash and I thought it was done for sure, but I rinsed that bad boy out and dried it up and it worked until I broke the glass bulb when taking it out of the black cap. Lol

[@d9zirable]

7:05 my meter tries to automatically match the calibration ph, when i press the calibrate button again while it's flashing, it doesn't do anything, it will not switch. now the readings are all messed up

[@MrDabrudda]

Try pulling out the batteries for about 10 minutes and try again.

[@loribadgero1035]

Thank you for this video! My, almost, brand new meter keeps acting up after changing batteries and calibrating, twice. I tried Physan 20 to clean it 🤷🏼‍♀️, but the isopropyl alcohol and hot water trick worked. I soaked it for a short time, too, and it finally zeroed. Whew!! 😰 ❤

[@vernonazusa5430]

Great Vid! My meter hasn't been used for a while and rinsed with tap water, so now readings jump up, down, zero and keeps repeating until eventually landing in zero. Going to try your method and do a full recal to pH water used for garden vegetable seeds germinating. Ever consider sharing your methods on how you get your PPM and pH died in via diy/budget method? Would ❤ to see that! Thanks again, and happy holidays to you and your fam!

[@yusritassiem9913]

it got wet on the inside so will most likely get corrosion on the inside as well which eventually is Gonna Give You a false readings or just packup

[@michaeljames5936]

Your method seems to work for you, but I would caution others, that most articles I've read, say to never store the bulb in deionised water, but to use 4.01 buffer solution and that exposing it to temperatures above 50C will kibosh it.

[@osmanfb1]

He is using degrees F ! 90F = 50C

[@generalawareness101]

I had a bad EC meter that they sent a pH, and the EC, meters that are going back on Monday as one pH meter works while the brand new one would Err on me when testing. Nothing fixed it.

[@maddavo565]

I have a meter from Amazon that is very similar to this BUT it automatically chooses the calibration solution rather than having to press the CAL button. Pressing CAL puts it into calibration mode, but subsequent presses do nothing, it automatically decides which solution it must be in. This is BAD. It thinks my 6.86 solution is 9.18. It thinks my 4,01 solution is 6.86. I'm stuck, IDK what to do.

[@gregandkellyone]

Same issue here, I need to reset pH calibration somehow....

[@cimorelos]

[@srmaozen4720]

Hello, I need your help. I fixed the voltage to 2.50. It gives accurate results in 7.01 solution. But when you measure milk, the voltage changes. so is it normal to give different voltage in each solution?

[@yclare1]

Thanks so much this video is so informative. Glad I watched before calibrating my new Ph meter.

[@patriciaahadzi8024]

Please I did my calibration the first one came right , second one should came out right but the third one 9.07 instead of 9.18 and it's stuck on a particular number which is 0.78 and with I put the pH meter in my product it read number and still stop at same number 0.78 please what should I do

[@ToluSeun]

how do I get mine to give accurate number? it's new. and I tried calibrating but it keeps flashing series of numbers and won't finish at the numbers on the buffers.

[@MrDabrudda]

You could try soaking the bulb in distilled water over night. If the bulb get dried out then it will give sporatic readings. Also check the batteries and ensure they are good.

[@MrDabrudda]

"If the electrode has not been hydrated (i.e. placed in solution for more than one hour), allow the electrode to soak in a buffer (preferably pH 4) prior to standardization or measurement. This will help optimize and re-establish the thin hydration layer on the sensing bulb, which is critical to pH measurement." www.coleparmer.com/tech-article/how-to-store-clean-and-recondition-ph-electrodes

[@genome692002]

thanks didnt know you have to press it again for a second time when calibrating ph 4.. the instruction manual was not very clear..

[@jkaytch]

Mine is stuck at ph 14.00 when I switch on. Any advice ?

[@CookieCreamOreo]

Great video! How long does your ph buffer solution last when you store it in the mason jars? I would love to save the money and not have to keep repurchasing it to calibrate my ph pen. I suggest you make a video on that because it would be very helpful for many. Thanks.

[@MrDabrudda]

I've had that PH meter for about a year. I don't cross contaminate the solutions because I alway rinse off the tip in distilled water before testing the other PH levels. I also store my solutions away from heat and light.

[@nicoherrerai]

Not a good idea, it changes unless you have ABSOLUTELY ZERO contamination, wich never happens in the real world

[@barteknowakowski1962]

@@nicoherrerai use distilled water, ideally :) it has ZERO contamination. And practically close to it.

[@Karaon]

worked, mine calibrated at 4.01 only and had errors on 6,86 or sth. I rinsed it nicely under hot water for a minute or two, then cleaned in distilled water. calibration went flawlessly after that, perhaps it's going to be a a routine for the cheap model if not used often

[@partridgeluke]

Mine says 1. And that's it won't change at all do you know what it is?

I haven't used my pH meter for about 6 years. It was covered with it's cap. I tired calibrating it with some 6 year old calibration solution... I don't know which is which is the problem lol.

[@MrDabrudda]

I'd soak it in warm distilled water over night and let the bulb rehydrate.

funny how u edited the third blink on 6.86 cause it always show error after 2 blinks

Gracias me salvaste una producción de cerveza.no funcionaba mí medidor de ph ahora si

[@barteknowakowski1962]

Ideally the little glass bulb should be continuously immersed in KCl solution in distilled water (4M). I wouldn't also use isopolypropylene alcohol on something that would be use in aquarium tank later on. There is no residue requiring non-polar solvents on it anyway. Use some acid solution to dissolve carbonates, that's it. PS especially using so much of isopolypropylene alcohol is NOT ecological friendly, my friend :)

[@MrDabrudda]

There is really no way to keep this meter's bulb submerged unless you stored it in a container of solution. I have an Arduino ph meter with a plastic screw on cap that I fill with distilled water with the pH adjusted to 4. I use there meters for making batches of liquid fertilizer for my plants and garden.

[@generalawareness101]

Incorrect, as IPA is environmentally friendly and Isopropyl alcohol is a natural product found in Mycoacia uda, Citrus hystrix, and other organisms. Not sure why you would think it wasn't ecologically friendly. Use 10k metric tonnes of it if needed.

[@tylerfosse7336]

DO NOT WHIPE WITH PAPER TOWEL!!! Do some more research. If you're going to dry it, use a cloth, and gently dab. Rubbing it can cause static to mess up the probe, these are VERY sensitive.

[@MrDabrudda]

A cotton cloth would probably generate more static than a paper towel anyways. Again...a $12 PH meter which is not that accurate in the first place.
