This EC meter is excellent for a range of applications. I've used it for water quality testing, gardening, and experiments. I also mentioned that I've been using the same gauge for a little over 7 years with no errors. I just had to change the battery and clean the probes from time to time. I love that it's waterproof as I've dropped it in water a few times and the seals are still holding up after 7 years of use. I definitely recommend this calculator.
