Calipers Appraisal

Pittsburgh Digital Calipers

The item is a set of digital calipers, presented within a black hard-plastic storage case with custom-fit foam inserts. The calipers themselves are constructed primarily from stainless steel, evident from their metallic silver luster, and feature a black plastic housing for the digital display and control buttons. The display is a rectangular LCD screen, currently unlit, indicating it is either off or without power. Below the screen, there are three distinct buttons: a red button on the left, a green button in the middle, and a black button on the right, likely for power, unit conversion, and zeroing functions respectively. The main beam of the caliper is marked with standard metric measurements in millimeters, clearly visible from '0' to '150', suggesting a maximum measuring range of 150mm (approximately 6 inches). The brand name 'PITTSBURGH' is boldly embossed or printed vertically along the lower section of the main beam, indicating the manufacturer. The movable jaw slides along the main beam, operated by a knurled thumb wheel located beneath the digital unit. There is also a small, silver-colored locking screw or knob positioned above the thumb wheel to secure measurements. The overall condition appears good, with no visible significant damage, heavy wear, or corrosion. The surfaces of the metal components seem clean and free from scratches, suggesting careful handling. The foam insert within the case is precisely cut to cradle the calipers, providing protection during storage and transport. The design is utilitarian, typical of precision measuring instruments, and likely dates from the late 20th to early 21st century given the digital display and plastic components. The craftsmanship appears competent for a mass-produced measuring tool, with clear markings and seemingly robust construction.
