The Dickey-John Grain Moisture Tester is a handheld device designed for measuring grain moisture levels. It's portable and powered by a single 9V alkaline battery, making it convenient to use in various locations. The device has a measurement temperature accuracy of ±2.0°C, which may not be the most precise but should be adequate for general use.

The USB connectivity adds a modern touch, allowing for easy data transfer and potentially integration with other devices or software. The tabletop mounting type suggests it's stable when in use, although this may limit its portability slightly compared to fully handheld versions.

Durability is not explicitly mentioned, but as it's made by DICKEY-JOHN, a reputable manufacturer, it likely offers reasonable longevity. This grain moisture tester is suitable for general use, particularly for those needing a portable and modern device with basic accuracy.

The Agratronix MT-Pro Portable Moisture Tester is a versatile tool designed for accurately measuring moisture in various grains. One of its standout features is the direct readout for 40 different grain scales, making it highly useful for diverse grain testing needs. It can test grains with moisture content up to 40%, which is quite high, and offers a readout accuracy of ±0.5%, ensuring reliable results.

The illuminated multilingual LCD display is another significant advantage, facilitating easier use across different languages and lighting conditions. The inclusion of a protective carrying case with a shoulder strap enhances its portability, making it convenient for field use. Additionally, the device supports both single-point and precision multi-point calibration, allowing users to match local elevator standards, further boosting its accuracy and usability.

The product dimensions (12 x 10 x 5 inches) and weight (1.94 pounds) are manageable but might not be the most compact or lightweight option available, potentially making it a bit cumbersome for some users. Despite being battery-powered and coming with included batteries, the reliance on a 9-volt battery might be considered a drawback for those who prefer rechargeable options. The Agratronix MT-Pro Portable Moisture Tester is a reliable and user-friendly device with excellent features for grain moisture testing, particularly suitable for users needing accurate and multilingual capabilities. Its size and battery type may not be ideal for everyone.

It provides accurate moisture readings quickly, which is a key advantage for those who need immediate results to make swift decisions. The ability to display both moisture and temperature simultaneously is another useful feature, helping users monitor environmental conditions that can affect grain storage and quality. An external temperature sensor can be added, enhancing its versatility.

Additionally, the backlit display ensures readability in various lighting conditions, making it convenient for use in different environments, whether in a dimly lit barn or out in the field. The unit is portable, though it may be a bit bulky for some users due to its 0.88-kilogram weight. Its tabletop mounting might not suit everyone, especially those who need to carry the device around frequently.

In terms of durability, the product appears to be robust enough for regular use. However, it's essential to handle it with care to avoid any damages that could affect its accuracy. The device is powered by alkaline batteries, which are readily available, ensuring that users can keep it operational without difficulty. For those seeking a reliable and relatively easy-to-use moisture meter for a variety of grains, the AMT65C serves as a good option despite some minor portability concerns.
