    Great value

    By Pete on Dec 20, 2019

    I needed a TDS meter to measuring nutrient levels in plant run off and picked this up because it was inexpensive. I've been using it for the last year and it has exceeded my expectations. It's far more accurate than I was expecting in a low cost meter and it's also very consistent. I will take multiple measurements that I know are within a close range, and the numbers are always what I expect. I have not calibrated the meter yet, but I know that my tap water is about 110-114 ppm and the meter usually reads within 2-5% of this. I recommend it for anyone who needs a fairly accurate reading but doesn't want to spend more on a more expensive meter.

    The working range in ppm isn’t high enough for aquariums
