Sir, after calibration in 6.86...when a checked the same for ph... without r holding or pressing calibration... reading of meter is 5.92.. After calibration at 4.....same buffer solutions shows ph 4.8 And after calibration at 9.18...same buffer solution shows 7.40 reading.... Is my pH meter ok interms of calibration...or the fluctuation of readings seems... error
I haven't used the pH paper. Here is something that I found. While both pH meters and pH paper are portable methods to measure a solution's pH, pH meters provide more accurate results and color blindness is not an issue as results are displayed on a digital readable display. However, pH paper is a much cheaper and easier way to measure pH.
I am not very sure about it but do keep it in some warm place, it might not be able to sustain so much of cold. Back in south India temperature hardly goes below 20, so I am not quiet sure about it.
Yes I have tried it once, result is more or less the same. I was checking in some forum people generally does that, also if you are buying the buffer powder to create the solution, do use a little and store the remaining in some container. It can be easily reused as well.
@@joy_of_life thank you🙏. So how much would you suggest of the buffer should I use for 250 ml solution so that I can recalibrate for future uses. As I have observed the whole package was used for the calibration. If need be then can we purchase more of the sachets? If yes can you provide the link.
take it a small/narrow container(your device should be able to go inside) and make sure the bulb in the front is completely submerged into the liquid, don't use wider vessel as it might take more liquid, you can search in amazon with "calibrating buffer solution" ... sharing the link from amazon india website www.amazon.in/Wellon-Buffer-Solution-Measure-Calibration/dp/B07YMSGSXT
one easy trick once you make the water ready just take some portion of the water and keep the remaining in a glass bottle and reuse them later, otherwise you will end up spending a lot
Not everytime, keep the calibration liquid handy. Just use it to check if you are getting the same reading from the calibration liquid. If it varies hugely then you need to recalibrate again.
This new pH meter me 00 Reading nahi aati Jo sahi nahi hai kiya ki naye instrument me 00 Reading aani chaiye Mai do din se 00 reding ka raha hai lekin nahi ho rahi
Just get pH testing paper kit, it's cheaper and easier to use .. 80 tests is 200Rs this kniva is a disaster, can't keep doing all this .. returning asap
Can we keep that solution for future use like for couple of months?
Yes you can
Can we store the water and reuse it next time?
Yes, you can
I have 7.0 ph buffer solution only. For the 2nd time recalibration, can i use 7.0 ph buffer solution??? Or the instrument only uses 6.86 to calibrate?
This device uses 6.86 only for calibrations
Out of 250 ml of given buffer solution i hav used only 20 ml and kept the remaining saftly. Can i use it for recalibration?
Yes, I do that often
It's perfectly fine to do that
You explained well. Thanks.
Glad it was helpful!

It isn't normal. Could be a faulty device as well. Try testing with an alternate device using the same solution.
Is battery water ok for calibration?
Many uses distilled water, I have never tried it personally
@@joy_of_life ok thank you
Hi Joy, Can i use pH Paper for getting the same result. Will it be accurate or useful like of pH meter ?

@@joy_of_life Thanks for the info.will use paper
Thank you for the wonderful video
I am glad that you liked it!
Just purchased it. Do we have to maintain 27 degree celcius? My place is cold so it's kinda hard to maintain the temp. Please let me know . Thank you

@@joy_of_life thank you for your prompt reply. Also can distilled water be replaced by mineral water?

caliberation required after every few days or what?
Quiet frequently, I am doing it in every 10-15 days
@@joy_of_life so these sachets are available in market to create this solution
yes, check the link below

How to use fish aquarium water?direct put meter to tank?
Calibrate the device, then take some water out of your fish tank in a cup and test.
@@joy_of_life every time need to calibrate?
Not everytime, keep the calibration liquid handy. Just use it to check if you are getting the same reading from the calibration liquid. If it varies hugely then you need to recalibrate again.

Faulty machine bhi ho sakta hai, Amazon se liye ho toh replace karwa lo
Mine giving error after flashing 6.86 :( any help
try re-calibrating with fresh solution
@@joy_of_life Checked with customer care and they have asked to return the item if getting error. 👍🏻
I have the same one
Cheap and good!

Will surely try it out, but his reliable it is?
Only time pass.
It just starts 6:50.
