In this part of the buying guide, the material and durability of the meters are reviewed. Materials of the soil moisture meter can guarantee a comfortable usage of the device without any issues. Soil moisture meters generally include various parts; first and foremost are probes. The probes are the most important part of your meter, as they directly contact soil for measurements. Stainless steel probes are the most common probe material and they are more resistant to erosion and can withstand soil moisture with varying pH values. Another less common material for probes is copper, offering more and better conductivity but susceptible to erosion. Another part of the meter is the case or body of the device, which protects internal sensors and electronics. Most meters offer plastic body material because it is moisture resistant and lightweight, making working with devices more comfortable. However, in extreme environmental conditions, their performance might degrade. Other devices offer rubberized cases to resist water and boost the durability of the device. The meter’s body must be sealed to prevent water penetration. This is done by epoxy resin and silicone seals.
Stainless steel probes of the soil moisturizers can be bought separately.
Some soil moisture meters are impact, water or corrosion resistant, making them ideal for outdoor usage in harsh environments. For example, the Vodeson 4-in-1 Plant Soil Moisture Meter has a waterproof and corrosion-resistant design that can remain in the soil continuously, needing only quarterly cleaning for optimal functionality.
In this section of the buying guide, we look at the measurement accuracy of the soil moisture meters. The measurement principles that are different for soil moisture meters. For a wider range of soil types, capacitive sensors are typically more accurate. While resistive sensors calculate resistance between two probes, the result can be affected by different conditions of the soil, such as salinity and temperature. Other, more expensive meter types are time domain reflectometry (TDR). These meters calculate the travel time of the electromagnetic pulse between two probes, resulting in more accurate measurements. There are different conditions related to soil that can affect the results of a measurement. First of all is soil type. Soils based on their ability to absorb soil affect the accuracy of the meters. For instance, clay soil absorbs water and can hold the soil moisture, while sandy soils drain quickly. Soil salinity is another parameter that can affect the measurement because high salinity can disrupt electrical conductivity, which the soil moisture meter uses. Soil temperature is important as well and can affect the resistive and capacitive sensors in soil moisture meters, leading to errors, although some meters offer temperature compensation algorithms to offset this effect. Another important element is that meters measure moisture in a specific depth and if the soil is heterogeneous, the soil moisture value can differ in other textures.
The soil type can have a major impact on the accuracy of a soil moisture meter due to their unique features | Extensive Buying Guideline of Soil Moisture Meters With High Measurement Accuracy
Soil conditions can impact the results as well. For example, many meters have optimum performance in a soil that is neither too dry nor too wet. Otherwise, the performance might be affected. The accuracy of the meters varies with each other. Take commercial soil moisture meters as examples, which offer ±3% to ±5% of the actual soil moisture content, while more professional meters, especially the TDR types, offer accuracy less than ±3% of the actual soil moisture content.
Soil moisture meters are user-friendly without any complex installation. However, here are some important elements that need to be considered: For installing the meter for continuous monitoring of soil, make sure that sensor is placed at the 15 to 30 cm (6–12 inches) depth, known as the root zone, because this area generally absorbs the most water. If you are using multiple meters, it is better to place them in different depths to get a broad picture of the soil moisture content in each layer of the soil. Another factor is sensor installation, making sure that the sensors probe in a vertical position, avoiding air gaps. The soil moisture meter is better placed in bare soils, avoiding large rocks or roots because they can affect soil contact.
To ensure accurate results, calibration is needed, although the meters come with factory calibration. However, if the reading is off and doesn't seem right, recalibration is required. Regularly clean the probs from dirt, salts, or organic matter; if they accumulate, they might impact the results. Use distilled water for this process and after drying, reuse the meter. Environmental conditions, such as extreme temperatures, fertilizers, and pesticides, can damage the soil moisture meters; therefore, protect the device from those.
The soil profile contains multiple layers and the best depth to place the sensor is 15 to 30 cm.
One of the important parts of selecting the right soil moisture meter is the power source, which will be discussed in this section of the buying guide. The most common source of power for soil moisture meters is batteries. First, there are meters that are not using batteries; they are analog and affordable, but their accuracy is not significant. The most common type is alkaline batteries, which are affordable but if you are using the meter frequently, it is not a good choice because it may require frequent changing. For consistent and large-scale monitoring, stationary meters are required that use external power sources.

This aids you in selecting the best option, preventing financial loss. First of all, take into account the soil type that is being measured. There are a relatively vast majority of soil types, such as agricultural soil, forest soil, urban soil, or arid land soil. The soil type is important because moisture content significantly varies in different soil types, ranging from very low in dry or sandy soils to higher in moist or clay-rich soils. Soil moisture meter measurements are specific, and the readings will vary significantly depending on the environmental conditions and soil characteristics. Since there is a relatively wide range for moisture in the soil, selecting the right soil moisture meters becomes essential. For example, moisture content in agricultural soils is from 10% to 40%, while forest soil has a higher soil moisture capacity up to 50%. Make sure to choose a device that covers a full range of soil moisture values that you wish to measure, because if the range exceeds, the results could be inaccurate or unreadable for you. Precision is another element that you need to consider based on your applications. Generally, the higher the moisture value, the greater the error in accuracy. However, generally, meters offer ±3% to ±5% of the actual soil moisture content, while more professional meters, especially the TDR types, offer accuracy less than ±3% of the actual soil moisture content.
Some soil moisture meters offer remote connection.
3.2 Evaluate the Existing System
The new soil moisture meter that you want to buy must be compatible with your current system, preventing unnecessary issues during installation or use. For example, if you have a centralized monitoring system that uses Wi-Fi or cloud platforms with multiple soil moisture meters, make sure that the new device is compatible with your other tools either for a better experience or data monitoring. Also, if your current system does not support Wi-Fi connections, it is worth it to update it with these kinds of technologies in order to get a better understanding of the soil moisture values. Advanced soil moisture meters require frequent calibration and maintenance to maintain their performance. Therefore, if your current system needs regular calibration, you can consider switching to a model with automatic calibration or minimal maintenance capabilities. Always check the power source when buying new soil moisture meters that are compatible with your other device. It is better that all the meters and sensors use the same power sources and are compatible with each other. The environment that you wish to use the meters in is another element. For example, if the meter is used outside, direct sunlight can cause overheating, leading to failure and inaccurate measurement of the device.
Price is an important element that can have a major impact on your options. The price range is broad and depends on several features, including the type of soil moisture meter, accuracy, measurement range, brand and additional features.
