If you need to have an up-to-date pH reading from your nutrient solution at all times, the Adwa Continuous Wall-mounted pH indicator is a great way to go; precise readings at all times.
This pH meter needs to be calibrated to pH 7 and pH 4 for the most precise results possible; it comes with the screwdriver used to adjust the pH. Its electrode is specifically designed to put up with highly mineralized water without breaking down.
It has a wide LCD screen that’s easy to read so that you can go about your business from a distance while checking it. It also has an automatic temperature compensation feature so that none of the readings are altered
You’ll need to plug it into the mains to have it on permanently; one of the best accessories for professional and home-growers alike.
