Review on Accurate Household Drinking Swimming Meter by Trevor French
Inaccurate pH meters
Follow calibration instructions. I could tell the number was far from first use. We tried to get it to work by comparing it to the strips, but the product didn't work properly every time we used it. When I realized that it was a bad purchase, the return period had expired. Well, this tester cannot be trusted.
