10 Best Milligram Digital Scales 2025 in the United States

The MAXUS Digital Milligram Scale is designed for precision weighing, making it a solid choice for those who need accuracy in measuring small quantities, such as in jewelry making, reloading, or handling various powders. With a capacity of 50 grams and an impressive readability of 0.001 grams, it stands out for its accuracy, which is essential for users who require exact measurements.

One of the notable strengths is its versatility in weighing units; it can measure in grams, ounces, and even carats, catering to different user needs. The tare function is another highlight, allowing users to subtract the weight of containers, which simplifies the weighing process. The inclusion of a 20g calibration weight helps ensure that the scale maintains its accuracy over time, which is a great advantage for users who frequently need to calibrate their tools.

The scale features a backlit LCD display, which enhances visibility, especially in dim lighting conditions. Additionally, its lightweight design and the option to power it via batteries or USB make it portable and convenient for both home and on-the-go use. There are a few drawbacks to consider; while the scale is compact, some users might find the size slightly limiting if they need to weigh larger batches. Also, the reliance on batteries could be a downside for those who prefer a scale that is solely powered by a wall outlet. Although the auto shut-off feature is useful for conserving battery life, it may interrupt use if users forget to disable it before prolonged use.

The LACHOI Lab Analytical Balance stands out with its impressive precision, measuring down to 0.1 milligrams (0.0001 grams) and handling weights up to 120 grams. This makes it suitable for tasks that require very fine accuracy, such as jewelry weighing or scientific research. It features a clear LCD display that shows measurements in multiple units, including grams, carats, ounces, and milligrams, which adds flexibility depending on your needs. The tare function allows you to subtract container weight easily, and the scale has useful extras like overload protection, counting, and fault alarms to help prevent errors.

Calibration is supported with included calibration weights, ensuring reliable accuracy over time, though the scale needs a 2-hour preheating before first use, which might be inconvenient for quick setups. The RS-232 port allows connection to printers or computers, although you will need to buy the cable separately. One drawback is the size and weight; at over 15 pounds and roughly 17 inches in each dimension, it’s not very portable or compact if you need to move it around often.

This scale is a solid choice if you want high precision and versatile functions primarily for stationary use in a lab or jewelry setting, but it’s less ideal if you need something lightweight and portable.

The Gemini-20 Milligram Scale is designed for precision and versatility, making it suitable for tasks such as weighing jewelry, medicines, coins, and even food. One of its notable strengths is its high accuracy, with a readability of 0.001 grams, which allows for precise measurements. The scale also offers a variety of units of measurement, including grams, grains, ounces, carats, troy ounces, and pennyweights, adding to its flexibility. Its maximum capacity is 20 grams, which is adequate for most small-scale measuring needs.

The inclusion of calibration weights and tweezers is a useful feature, ensuring that you can maintain accuracy over time and handle delicate items easily. The tare function allows you to reset the scale to zero with containers on it, making it simple to measure contents only. The LCD display is clear and easy to read, though it may be less effective in very bright or very dim lighting conditions. This scale is powered by 2 AAA batteries, which are included, making it convenient to use right out of the box.

One of its standout benefits is its portability; it's compact and lightweight, with dimensions of 4.94 x 6.5 x 1.62 inches and a weight of just 4.23 ounces, making it easy to carry around. However, the small size may also be a drawback for those needing to weigh larger items. The flip-down shield protects the weighing surface during transport, but the scale itself can be prone to damage if not handled carefully, as it is a delicate instrument. The Gemini-20 Milligram Scale is a reliable and portable option for precise small-scale measurements, ideal for travel and versatile applications, though users must handle it with care to avoid damage.
