10 Best Hay Moisture Testers 2025 in the United States

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 ZOEYEC TK100H Portable Hay Moisture Meter is designed for measuring moisture in various types of forage like cereal straw and different grasses. It is a lightweight and portable tool that is easy to carry around, making it convenient for field use. This meter provides basic moisture readings, which is essential for ensuring hay and forage are stored properly to avoid spoilage.

Its compact size and design suggest decent durability and suitability for farmers or livestock owners who need a straightforward, portable tool for quick moisture checks rather than highly precise lab-level testing. For users seeking advanced accuracy or detailed specifications, other models may better meet those needs.

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.
