If your pH meter is going crazy showing variable numbers, let it be on for a while in a glass with little bit of tap water and it will fix itself, mine goes crazy when it's dry I leave it in water and in 30 mins or less it starts stabilizing. Hope it helps
It will be more economical to use this one with Arduino instead of buying the Arduino PH sensor.is it possible to connect the buttons to micro controller like Arduino. How to interface the lcd.
If you believe that pH measurement is related to electrical conductivity of the solution, then definitely you have a lot to learn about pH. You will discover that all the magic is in the little glass pulp, the critical and essential part of such devices.
In a standard process in industry you often use ec to know how much acid or caustic to add in your product to reach a certain pH. Oc the material has to be the same always. For example you add HCl. It dissolves in water to H+ and Cl- increasing the EC. Our product is standardized to 7.6 MS/cm and we always get an ph of 6.8. Oc it only works in one direction. The reason ph sensors arent used extensivly in the food industry is, they brake alot bc of 130°C sterilisation and afterwards cleaning with caustic and acid. You are the one who needs to learn alot.
my ph meter reading is showing in rain water 8.2 but shop water 6.5 ..... reverse type. is it possible to solve by using buffer solution...??? what can i do????
Nope the glass bulb is actually not the same glass with a bulb, normal glass is highly non conductive, ph sensing bulb glass is specifically formulated to both conduct electricity and select hydrogen ions.
@@programcoffee1080 What legs are the signal? Do you have any materials online so that we can work with? These pens are really cheap when compared to a "professional" arduino sensor with converter. If it shows a number on that LCD then I'm pretty sure there is some sort of converter that we can leech the results to an external microcontroller. Teach pls? :)

This is happening to be right now... hope it stabilizes

Good idea, how far have you gone down this track?

You didnt even dig into the sensor. What a waste.
I broke the glass bulb of my ph meter, it can still be in use?
Nope. It's broken now.
This you call a teardown? Half a strip and we're done?
can we use any other thing instead of broken glass
You can try to DIY with those Christmas glass balls (the very thin ones) but the precision is terrible... better to buy one.

can i make this with arduino uno?
Yes :D
