Buying Guide

You have already read reviews of the best soil moisture meters. Now, how will you find the right device for your needs? Before providing you with a comprehensive guide, we need to say that soil moisture meters are of different types.

Analog meter

It has a simple and minimalistic design that does not need a battery. It needs electricity, which occurs naturally in the soil. The soil’s moisture content reaches the tip of the meter’s probe and emits a charge to give you readings.

Digital meter

Digital soil moisture meters need batteries to display information on the screen. However, the best fact is that their probes have no corrosion risks. Thus, although you have left the device in the soil for several hours, the probe will not get damaged.

You need USB cables to charge the device, and you may transmit the data to your PC.

Hybrid soil moisture meters

These devices are multifunctional solutions, as you can use them to measure sunlight intensity and hydration level. While measuring the moisture, the device checks the pH level. However, you may find these devices in both analog and digital versions. You can invest in these products for composting, as the soil must have the proper hydration level for microbial growth.

To buy your soil moisture meter, you have to focus on some factors.

  • Easy-to-use device with clear display

Moisture meters with user-friendly designs make it easy for you to measure the water percentage in the soil. Thus, as a beginner, you have to look for an intuitive soil moisture meter. In most cases, you may operate the device by touching a button.

The most important part of the device is the display. The screen has to show the moisture level of the soil. The moisture level can range from 1 to 10, and based on the position of the dial, you can check out the water content of the soil.

For flower plants, like lavender, aster, and poppy, the moisture level has to range from 21 to 40% (Level 3 to 5). However, some other flowers need a higher amount of moisture (3 to 9). Lots of plants, like cactus, survive drought (1 to 3).

You may not know the right moisture level for your plants, and thus, manufacturers add an instruction book to the package to help you in gardening.

  • Availability of innovative features

Do you need to measure only the water level of soil moisture meters? Some gardeners like to check other qualities of the soil. That is why manufacturers integrated special sensors to detect the soil’s temperature, light, and pH level. By investing in one device, you will have multiple functionalities. The single-feature device may be simple for your use. Still, 3-in-1 devices are better options for your needs.

  • The accuracy level of the measurements

The inaccurate measurements of soil moisture and other conditions can affect plant growth. That is why you have to check out the level of accuracy of the final readings.

  • Probes of soil moisture meters

You can find soil moisture meters with one-probe and two-probe designs. The stainless steel probes have no rust issues. However, some metal problems may have corrosion problems when you have left them in the soil. It is better to clean the probe after every use to avoid any damage to this part. The sensor on the metal problem may lose its sensitivity while you have not taken it out of the soil for long hours. 

Conclusion

Now, are you ready to buy the best soil moisture meter for your purpose? You can check out these devices’ features to measure the soil moisture, temperature, and other factors.
