    Not for aquariums

    By on

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

    Great value

    By on

    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.

    Great meter reader for my aquarium

    By on

    I needed a meter that would test my water parameters and I ordered this from Chewy. The shipping was fast and on time and the meter is accurate and easy to read. I recommend Chewy and this product anytime
