Review on PH Meter, TDS PPM Meter, Soil PH Tester - Digital Kit (3 Pack): Accurate Testing for Optimal Growing Conditions by Heidi Massine
pH meter calibration off
PH. The counter is calibrated. many times. Constantly inaccurate. Tested with pH Power in distilled water and compared to a brand new "brand" pH meter. Using a water stir meter, the reading was +0.40 ish. If the device is idle, the pH value continues to rise. The other 2 meters are fine. *Water plants with incorrect pH up/down. Leads to pH blocking. A nutrient vampire in a plant. Brown spots, leaf curl, leaf fall. In my opinion, if you care enough about your plans, buy a counter. Spend a few dollars more. Buy a brand that has a guarantee.
- Ideal for a small home
- Slightly wrinkled
