Review on Sonkir Soil pH Meter: 3-in-1 Tester for Soil Moisture, Light, and pH Levels. Includes TDS Meter & Temperature Sensor for Liquid and Soil Testing by Julio Montano

I bought a pH meter to measure the pH of the soil in our garden. This combination product was found in a search and purchased for combined use. Order arrived on time via Prime. 3-in-1 soil tester: no batteries required, great! It helps measure soil pH, moisture and light. The interest was in measuring the pH of the soil and testing it in several spots and it came out just over 7. I'm glad the pH levels are in a good place. TDS Meters: Both meters provide instant results. 61. It is good that we have water of excellent quality. I will give my kids a handy TDS meter. Solution pH Meter: We need to calibrate with the provided pH test material and we need distilled water. It didn't matter as my goal was to measure the pH of the soil, which works great.
