The FW3000 4-Way Soil Analyzer Shows pH levels from 0 - 9. Provides the percentage of moisture in your soil. Lets you know when fertilizer levels are too high or too low. Identifies light levels to help you find the perfect spot for shade, part shade, and sun plantings. Easily switches functions. Simply insert into soil and flip the lever to the reading you want to take.
How the meter works: The pH meter works by using different metals in the probes. When they are inserted in damp soil, the different metals react with each other to create an electrical current. The meter measure the electric current, and that's how it reads the soil pH. Like many metals exposed to dampness, over time, the metal on the right probe has a tendency to oxidize, which puts a coating on the probe, and prevents it from correctly working. That's why a cleaning pad is included. It is specifically designed to clean this probe.
Tip: Make sure you clean the probe, moisten the soil and wet the probes before using.
