The device boasts a measurement range of 5% to 40% moisture, suitable for most grains, and operates in temperatures from 0° to 45° Celsius, which adds to its usability in different environments.

The multilingual LCD display is a notable feature, allowing users to select from several languages including English, Spanish, and French, making it accessible to a wider audience. Additionally, its USB compatibility enables easy software updates and personalizations, enhancing its functionality. Portability is another advantage, as it comes with a carrying case equipped with a handle and strap, making it convenient for field use. However, weighing 8.2 pounds, it might be slightly bulky for some users.

Durability seems to be well covered with its robust design and the inclusion of a carrying case for protection. On the downside, it requires 4 AA batteries, which are not included, potentially adding to the running cost. The product has been available since 2014, indicating it’s a tried and tested model, but it may lack some modern features found in newer models. The AgraTronix 30100 offers reliable performance, multiple language options, and good portability, although its weight and battery requirement could be minor drawbacks for some users.

The AgraTronix MT-16 Portable Grain Moisture Tester is designed for accuracy and convenience, making it a solid choice for farmers, cultivators, and grain sellers.

The backlit display with multilingual settings ensures readability even in low light conditions, which is a nice touch for those working in various environments.

Additionally, the tester can average up to 99 test results, providing a comprehensive overview of moisture levels. Portability is another advantage, with its compact size and lightweight design making it easy to carry around, especially with the included protective carrying case and shoulder strap. However, there are some drawbacks to consider. The device requires two 9V batteries, which, while included, could be seen as a hassle for some users who prefer rechargeable options.

Also, while the moisture display resolution of 0.1% is quite precise, some users may find the relatively small display dimensions (7 x 3 x 3 inches) a bit challenging to read. The MT-16 functions well within a temperature range of 32° to 113°F, but extreme conditions might impact its performance. In summary, the AgraTronix MT-16 offers reliable accuracy and ease of use, making it a suitable tool for those who need a portable and versatile grain moisture tester, despite its minor inconveniences related to battery usage and display size.

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.
