10 Best Hay Moisture Testers 2025 in the United States

The Delmhorst FX-2000 Hay Moisture Meter Tester is designed specifically for assessing moisture levels in hay, making it an excellent choice for farmers and ranchers looking to ensure optimal storage conditions. One of its notable strengths is its moisture range and accuracy, which allows users to get precise readings crucial for preventing spoilage and maintaining hay quality. The 10-inch probe length enables deeper penetration into the hay, ensuring a thorough measurement. Additionally, the continuous mode feature is a standout, producing two readings every second, which is beneficial for users who need quick and efficient assessments, especially when working with large quantities of hay.

The display type is user-friendly, showing averages and high readings, which simplifies the interpretation of results. The device also offers temperature compensation, enhancing its reliability under varying environmental conditions. Its durability is another positive aspect, designed to withstand the rigors of farm use, thus promising longevity.

There are a few drawbacks to consider. The FX-2000 does not come with batteries included, which may be an inconvenience for some users who expect a ready-to-use device. Furthermore, its relatively high weight of 5.04 pounds could be a consideration for those looking for a more portable option, particularly if they need to carry it around frequently.

The Delmhorst RDM3 Moisture Meter is a solid choice for checking moisture levels in hay and other agricultural materials. It uses pin-type measurements, which provide a direct and reliable moisture reading by physically penetrating the material. The digital display makes it easy to read results, and the built-in alarm can alert users when moisture reaches critical levels, helping to prevent spoilage.

It also features data logging, allowing you to keep track of moisture over time, which is helpful when monitoring multiple samples or batches. The meter runs on a standard 9-volt battery, which is convenient and included with the package. It can handle temperatures up to 100°C, making it durable enough for most farm environments.

This user-friendly device includes important features like temperature compensation and data logging, making it well-suited for farmers or professionals who want a dependable tool without complicated setup.

The Delmhorst TECHCHECK-PLUS Moisture Meter is well-suited for hay moisture testing, offering a good balance of features that meet the needs of users, especially farmers and agricultural professionals. One of its main strengths is its bright, clear digital display, making it easy to read measurements, even in various lighting conditions. The meter provides an impressive moisture range of 0.1% to 60%, ensuring it can effectively measure moisture content in both drywall and wood, which is helpful for users who might also be dealing with different materials. The scan mode allows for quick assessments over a broad range, which could be beneficial when testing large bales of hay or other agricultural products.

However, there are some limitations to consider. The integral contact pins, while useful for direct penetration, only offer a 5/16” depth, which may limit the reading's accuracy in denser materials. Additionally, the device operates on a 9-volt battery, which could require frequent replacements depending on usage frequency. Also, while the device's build quality is reasonable, it may not be as rugged as some users might prefer for harsh outdoor conditions, particularly in agricultural settings.

The Delmhorst TECHCHECK-PLUS is a reliable tool for anyone involved in hay moisture testing, balancing ease of use with functional features. Be aware of its limitations regarding penetration depth and potential battery life to ensure it fits your needs effectively.
