10 Best Hay Moisture Testers 2025 in the United States

The F-6/6-30/18/PKG Analog Hay Moisture Meter Deluxe 18” Package by Delmhorst is a practical tool for farmers and hay producers needing to monitor moisture levels in their hay. It features an easy-to-read analog display which makes it user-friendly. The moisture range it can measure is from 6% to 31%, which is broad enough for most hay moisture-testing needs. The device also includes an 18-inch probe, which is adequate for reaching deep into hay bales for accurate measurements.

An internal calibration check helps ensure ongoing accuracy. The device doesn't rely on batteries, which is convenient and reduces ongoing costs. It also comes with a 1-year warranty, providing some assurance of durability and reliability. The moisture meter is built to operate in humidity levels between 10-90%, which covers most typical conditions. It is lightweight at 1.5 pounds and comes with a carrying case, handle, and additional probe for added functionality and ease of transport.

The lack of temperature compensation might affect accuracy in varying environmental conditions. The analog display, while easy to read, may not be as precise as digital options. The product is also relatively large with package dimensions of 24 x 8.5 x 4.7 inches, which might be cumbersome for some users. Despite these minor drawbacks, it serves well for those who need a reliable, easy-to-use moisture meter for hay.

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 Agratronix Windrow Hay Moisture Tester is designed to measure the moisture content in hay with a range of 13-70%, making it versatile for various stages of hay processing. Its accuracy is appreciated by users. The device features a clear display for easy reading. The tester is made from durable aluminum, ensuring it can withstand rough field conditions. It is relatively lightweight at just over 2 pounds, making it portable.

One notable drawback is the need for a 9V battery, which is not included. This could be inconvenient for users who need to use the tester immediately out of the package. While it ranks moderately well in the niche category (#138 in Moisture Meters), it isn't one of the top choices in the broader Tools & Home Improvement category. For farmers and professionals needing a reliable and durable moisture tester for hay, this device offers a good balance of features and user satisfaction.
