10 Best Hay Moisture Meters 2025 in the United States

The AgraTronix Hay Bale Moisture Tester HT-Pro is a handy tool designed to help farmers and hay producers accurately measure moisture content in hay, which is crucial for preventing spoilage and maintaining quality. It offers a moisture range between 8% and 44%, which covers the typical levels you’d want to check in hay bales. The 20-inch probe is a good length for reaching inside large bales, giving a better reading of the moisture deep within, not just on the surface.

The tester includes a clear, illuminated LCD display that shows results easily, even in low light conditions. It also has helpful indicators that alert you if the moisture content is above or below safe levels, making it simple to know when hay is ready for storage or needs further drying. The ability to calibrate the device with a provided clip helps maintain accuracy over time, which is important since moisture meters can drift with use.

In terms of durability, the unit is built with plastic and metal parts and is handheld and lightweight (about 1.15 pounds), making it portable and easy to handle in the field. It runs on a 9V battery, which is common but not included, so you will need to keep spare batteries handy. For most farmers who want a reliable and straightforward moisture meter to protect their hay investment, the HT-Pro offers a solid balance of features without being overly complicated.

The Agratronix Windrow Hay Moisture Tester is designed to help farmers and agricultural professionals accurately measure the moisture content of hay. It offers a moisture range of 13-70%, which is quite broad and suitable for most hay conditions. The device does not include batteries, and you will need to purchase a 9V battery separately for it to function. The build quality, made of aluminum, suggests good durability, which is essential for agricultural environments.

At a weight of 2.07 pounds, it is fairly portable, though the probe length is not specified, which might be a consideration depending on the user's specific needs. The product has been available since 2012 and ranks #138 in Moisture Meters, indicating it is a well-established choice in its category. Users looking for a durable, reliable hay moisture meter with a good range and ease of use might find this product a suitable option, despite the minor inconvenience of needing to purchase a separate battery.
