This 3-in-1 analogue soil meter is perfect for getting an idea of the pH, moisture, and light levels of a given area. Measurements are displayed on a simple dial, allowing for an approximate value to be read quickly and easily, and the analogue nature of the meter means that it does not require batteries. Two metal probes take the measurements for pH and moisture, while a small light sensor reads light levels. pH values from 3.5 to 8 are displayed, along with a 1-10 scale for moisture and light range of 0 to 2000 lux. An excellent cost effective way to take soil measurements.
