Best Soil Meter Buyer’s Guide

The Most Important Features to Consider

  1. Measurement Metrics
    Many soil meters can perform multiple types of measurements, including the measurement of pH levels, moisture levels, and light levels. These multimeters typically allow for simple adjustments between measurement metrics via the press of a button. Be sure to read the fine print, however, as not all soil meters are designed to conduct all measurement types, as some can only handle one or two different metrics.
  2. Ease-of-use
    Look for gardening tools that are extremely easy to use, with lengthy probes that easily insert into soil, conducting their measurements immediately, in the case of moisture or light, or taking several minutes, in the case of testing the pH of your soil. The best soil meters also feature bright and easy-to-read displays that easily provide results of said measurements. Most soil meters also use simple designs that do not require any external power sources, so they do not require batteries.
  3. Probe Length
    Make sure the soil test kit you choose features a lengthy probe of around seven to eight inches, or longer, so as to reach as close to the root as possible, for the purposes of providing accurate readings. You may want to also choose a soil meter with a single probe design, as these cause less soil disturbance during use.
