Im only writing to tell you that if want the best, look no further. Ive had this meter for 3 years and its only gotten more accurate. I keep it calibrated and use storage solution to maintain it. It never fails, and rarely if ever deviates from target ph or ec, not common with most meters. Its expensive, but i dont have to worry about accuracy and i dont worry about probe failure.
