First Microscope with Built-In Scale

The TOMLOV DM4W combines a 4.3" digital microscope with a precision weighing base. Collectors, jewelers and lab users can inspect surface details and read weight in grams, ounces or carats on the same screen without moving the specimen. It is not for buyers who need higher magnification than the fixed screen provides.

0.1 g Resolution and ±0.3 g Accuracy

The integrated scale handles 1 g to 300 g with a 0.1 g division and approximately ±0.3 g accuracy. A high-precision sensor delivers stable readings for verifying coin authenticity, grading gemstones or checking precious-metal content. The single figure that decides fit is whether 0.1 g resolution meets the user’s tolerance.

8 in Stand with Metal Support Rod

The stand rises 8 in and includes an enlarged base plus a built-in metal support rod for extra stability during focus adjustments. Power comes from a NiMh battery pack rated at 1500 watt_hours at 5 volts, so no mains cable is required at the workstation. The unit ships in a 12 pack container measuring 8.5 in x 6.9 in x 3.5 in.

Questions about this item

What does the 0.1g resolution mean when I am actually weighing a coin?

The scale shows weight changes as small as 0.1g so you can see fine differences between similar coins or detect wear that shifts the reading by a fraction of a gram.

How does the USB connection limit what I can do with the live image?

The USB link lets you view and capture the microscope feed on a Windows or Mac computer but it does not carry video to a monitor without a PC.

Will the 8.5 in tall stand fit on my crowded bench?

The stand reaches 8.5 in high with a 6.9 in deep base so you need at least that much clear depth and vertical clearance.
