10 Best Hay Moisture Testers 2025 in the United States

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.

The AgraTronix Hay Bale Moisture Tester HT-Pro is a specialized tool for farmers and those working with hay. With a moisture range of 8% to 44%, it covers a broad spectrum of moisture levels, making it versatile for various conditions. The 20-inch probe length ensures that users can reach deep into hay bales for accurate readings. The illuminated LCD display is a standout feature, providing clear visibility in low light conditions. Accuracy is enhanced with the included calibration clip, which helps maintain precise measurements over time.

Additionally, the tester indicates when moisture levels are above or below set limits, offering a helpful guideline for optimal hay storage and usage. However, one potential downside is that it does not include temperature compensation, which could affect readings in fluctuating temperatures. The device is lightweight at 1.15 pounds and handheld, making it easy to carry around and use. Durability appears adequate with a 1-year warranty for material and workmanship, though it is primarily made from plastic and metal.

The product operates on a 9V alkaline battery, which is commonly available but not included. This hay moisture tester is recommended for anyone who needs a reliable tool for monitoring hay moisture levels, particularly useful for farmers and agricultural professionals.

The Draminski Hay & Straw High-Moisture Meter with Probe Plus Temperature Display offers a range of useful features for anyone working with hay or silage. It has a moisture range of 10-80%, which is quite broad and should be sufficient for most needs. The 22-inch probe length allows for deep insertion into bales, providing more accurate moisture readings. It is capable of displaying temperature in degrees Fahrenheit, which is a handy additional feature.

The large number LCD display makes it easy to read data even in low light conditions. Additionally, it includes minimum, maximum, and average functions, offering a comprehensive view of moisture levels. One downside is the relatively high weight of 1.36 kilograms (about 3 pounds), which may make it cumbersome to use for extended periods. It requires a 9-volt battery but does not include one, so you will need to purchase this separately.

Durability seems to be good with a sturdy build, though it may not be the most portable option due to its size and weight. Priced reasonably, it represents a good investment for farmers or anyone needing reliable moisture measurements in hay or silage. However, if you need a more lightweight and portable device, you might want to explore other options.
