The Agratronix Advanced Hay Straw and Silage Moisture Tester is a robust tool designed to help farmers and agricultural professionals measure the moisture content in hay, straw bales, and silage accurately. With a moisture measurement range of 8% to 72%, it covers a wide spectrum suitable for various farming needs. The 20-inch stainless steel probe is particularly useful for dense bales, offering durability and ease of handling due to its rubber grip handle. This makes it less likely to suffer damage over long-term use, even under heavy-duty conditions.

The automatic density compensation feature ensures that the readings are adjusted based on the density of the bale, enhancing the accuracy of the results. The bright LCD display is user-friendly, allowing for easy reading both during the day and at night, and supports multiple languages including English, Spanish, French, and Portuguese, making it accessible to a broader range of users. Additional customizable modes for different types of materials (hay, straw, silage) further ensure precise readings tailored to specific needs.

Temperature compensation is another strong point as it can measure temperatures between 14° to 176° Fahrenheit, which is crucial for accurate moisture readings. The tester requires a 9-volt battery, which is not included, potentially adding an extra step for users before they can start using the device. It also has a USB port for saving readings and downloading firmware updates, adding a layer of convenience. This moisture tester is portable, weighing 3.34 pounds, making it easy to carry around the farm.
