Analytical Laboratory Balance (Two-Pan Scale)

The item is a two-pan analytical balance, likely a triple beam balance or similar laboratory/precision scale. Its primary components include a sturdy, rectangular base structure, a central column supporting the balance mechanism, and two circular weighing pans. The base appears to be constructed from a light-colored, possibly beige or cream-colored, painted metal or heavy-duty plastic, exhibiting some surface wear and minor discoloration consistent with age and use. The balance arm, connecting the two pans, appears to be made of dark-colored metal, possibly painted cast iron or steel, showing some loss of finish or scuffs. The two weighing pans are circular, made of a lighter, metallic material, such as stainless steel or aluminum, with a brushed or matte finish, showing signs of use with minor scratches and smudges. A prominent feature is the central dial and indicator mechanism located below the balance arm. This mechanism includes a large, ridged black knob, likely for fine-tuning the balance or taring, surrounded by a white or light-colored face with numerical markings ranging from what appears to be 0 to 50, with subdivisions, and additional markings for 0.5 and 1.0. Above this dial, a vertical pointer swings along a marked scale to indicate equilibrium or weight difference, which also shows some discoloration. The overall construction suggests a robust and functional design, built for precise weighing. There are no clearly visible manufacturer's marks or model numbers in the provided image. The aged appearance, particularly the wear on the painted surfaces and the patina on the metal components, suggests that the balance is not new and could date from the mid to late 20th century. The craftsmanship appears utilitarian and robust, designed for practicality rather than aesthetic finesse, indicative of a scientific or industrial tool.
