10 Best Plant Moisture Readers 2025 in the United States

The XLUX Soil Moisture Meter is a useful tool for gardeners and plant enthusiasts who want to monitor the moisture levels of their soil accurately. Its sensor can determine if the soil is dry, moist, or wet, providing more reliable readings than simply using visual or tactile assessments. The large dial is easy to read with clear zones and scales, making it accessible for users to understand the moisture levels quickly.

One of its standout features is the immediate moisture reading, which offers instant feedback without waiting, allowing for timely watering decisions. The single probe design minimizes damage to plant roots and avoids extracting too much soil, which is beneficial for plant health. However, users should be cautious and avoid leaving the probe in the soil for more than 5 minutes to prevent corrosion of the metal tip. It is also not suitable for testing very hard soil or any liquids, limiting its versatility somewhat.

Additionally, the product doesn't require batteries, making it hassle-free and easy to use. It is lightweight and has an upper temperature rating of 45 Degrees Celsius, suitable for both indoor and outdoor use. The XLUX Soil Moisture Meter is efficient for those needing to measure moisture in typical garden soil, though it may not be ideal for very hard soils or other mediums.

The SONKIR Soil pH Meter, model MS02, is a versatile 3-in-1 gardening tool that measures soil moisture, pH value, and sunlight levels. It is designed for use in various settings, including gardens, lawns, farms, and indoor plants. One of its notable strengths is that it doesn't require batteries, making it convenient and easy to use—simply insert the probes into the soil and get readings within minutes on the readout panel.

The device is built with sturdy materials, ensuring durability for long-term use. Its compact and portable design makes it easy to carry around and employ in different locations. However, users should be aware that this meter is not suitable for testing the pH of liquids, and it may not provide accurate readings if the soil is too dry; in such cases, watering the soil before testing is necessary.

The meter is well-regarded, with a strong customer review rating of 4.1 out of 5 stars from over 43,000 reviews. Measuring 11.5 x 2 x 1.5 inches and weighing just 2.89 ounces, it is lightweight and easy to handle. This product is especially useful for gardeners and plant enthusiasts looking for a reliable and multipurpose soil testing tool. However, it may not be the best choice for those needing highly precise or professional-grade measurements.

The XLUX Long Probe Deep Use Soil Moisture Meter Sensor is designed to help you easily monitor the moisture levels of your plants, whether for indoor or outdoor use. One of its standout features is its long probe, measuring 5.5 inches, which allows it to reach deeper soil levels in larger pots. This can be particularly useful if you have big or deep planters where surface checks are not enough.

The device provides immediate moisture readings, so there's no waiting time - simply insert the probe and read the dial. The easy-to-read large dial with three zones and ten scales makes interpreting the results straightforward. It's also designed to minimize root damage, thanks to its single-probe design.

There are some usage precautions worth noting. It's not suitable for very hard soil, and it is not designed to test water or other liquids. The metal tip can corrode if left in the soil for too long, so it's advised not to leave it in the soil for more than five minutes. The meter is lightweight, which makes it easy to handle, but it might not be as durable in tougher conditions. For gardening enthusiasts or those managing larger potted plants, this moisture meter offers a practical solution for maintaining optimal soil moisture levels.
