Hi to all
Wanted to share with you guys on how I source a Industrial grade PH digital monitor and use it on our hobby. You can look for the monitor in Taoboa, the cost of one meter with the probe can be less than S$100, depending on model and specs.
I am sure since this is being used in industrial application, the accuracy and longevity of it should be better than our hobby grade.
You probably can source the casing to make it as compact as possible, but for my case, since this is a trial, I just go to Sim Lim and buy off the shelf water proof casing for $17...
The PH probe using the free holder that they give to me....
