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

    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.

    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!

    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

    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?

    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

    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.

    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.

    "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

    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 :)

    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.

    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.
