10 Best Hay Moisture Testers 2025 in the United States

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 Agratronix BHT-2 Advanced Baler-Mounted Hay Moisture Tester is designed for farmers and agricultural professionals who need accurate moisture readings to ensure quality hay. One of its notable strengths is the multi-sensor technology, which provides readings from both sides of the bale and through it, enhancing accuracy. The average readings are updated every 2 to 3 seconds, allowing users to monitor moisture levels in real time, which is essential for preventing spoilage.

The large LCD display is another plus, making it easy to view results in various lighting conditions, whether it's day or night. Users can also set their own moisture limits, which adds a layer of customization and helps in making quick decisions about the hay's condition.

There are a few drawbacks to consider. While the moisture range and accuracy are good, some users might expect even higher precision, particularly for critical applications. Additionally, the product's age, first available in 2012, may raise concerns about its longevity and advancements in technology compared to newer models. Moreover, since it does not come with batteries included, users will need to prepare for that extra cost. Durability is acceptable with its ABS material construction, but practical use in demanding agricultural environments might challenge its resilience over time. The Agratronix BHT-2 is a solid option for those needing reliable hay moisture readings, offering user-friendly features and good performance, though potential buyers should weigh its limitations against their specific needs.

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.
