Review on 🔍 ROOYLE Digital pH and TDS Meter Combo with ±0.01 pH Accuracy and ±2% Accuracy by John Bailey

The water filter brochure said we had something to measure water quality (I never would have thought of that). I knew we had hard and horrible water but I just couldn't believe it when I saw the numbers for our tap water - as you can see in the picture! I took various samples to make sure this thing was working: Tap water - 722 (oh my god that's well over the maximum limit) Filtered with fridge filter - 473 (I can clearly see the filter needs changing) Newly replaced water filtration system - 138 (since it's dropped below 100 so I know it's better) Bottled water - 16 I didn't even know what I was expecting but looking at those numbers I realized I had another one had to make a few changes. It was pretty easy to use. The PH I haven't used I don't know at the moment when I will use it as my main concern has been the water quality and making sure we change these filters when the quality starts to drop. Ople with a water filter is definitely a great addition as sometimes the recommended timing is different if your water is as unpleasant as ours.
