A&D Weighing MC-1000S Mass Comparator Balance, Internal Calibration, 1100 g x 0.0001 g

The A&D MC-1000S has a maximum capacity of 1,100 g with 0.0001 g (0.1 mg) readability. It uses a 128 × 128 mm weighing pan and provides the extended resolution needed to detect very small mass differences, making it suitable for precision mass comparison and calibration laboratory applications.

The MC-1000S is designed for professional mass-standard management. A&D specifies the MC Series for OIML Class F1 and lower-class weights, while A&D's U.S. product information also identifies it for metrological weighing involving ASTM Classes 2–7. This makes it suitable for calibration laboratories, metrology facilities, and quality-control departments.

The MC-1000S package includes an auto-centering pan that automatically helps align the center of gravity of the test weight with the center of the weighing pan. This reduces eccentric or corner-loading errors caused by inconsistent weight placement and can improve repeatability during high-precision mass comparisons.

Yes. The MC-1000S features an internal calibration mass, allowing users to perform calibration conveniently without relying solely on an external calibration weight. A&D describes the internal calibration function as a way to help maintain balance accuracy with a simple calibration operation, which is valuable for routine laboratory workflows.

Yes. The MC-1000S configuration includes a glass breeze break. By reducing the influence of air drafts around the weighing area, the breeze break helps create more stable conditions for measurements at the balance's fine 0.0001 g readability. This is particularly useful during demanding mass-comparison work where small environmental disturbances can affect results.
