MC-10K, MC-30K specifications

The A&D MC-30K and MC-10K are highly regarded weighing scales that cater to diverse industrial and commercial applications. Renowned for their accuracy, durability, and advanced technological features, these models are ideal for users who require precision in measurement.

The MC-30K model offers a capacity of up to 30 kilograms, while the MC-10K is designed for loads of up to 10 kilograms. Both models are equipped with high-resolution load cells that provide outstanding accuracy and stability in measurements. The readability of 1 gram for the MC-10K and 5 grams for the MC-30K ensures that even the smallest variations in weight are captured effectively, making them suitable for activities ranging from laboratory analysis to quality control in manufacturing processes.

One of the standout features of these scales is their easy-to-read LCD display, which allows users to view measurements clearly, even in low-light conditions. The display is designed to provide quick and efficient readouts, minimizing wait times during the weighing process.

Both the MC-30K and MC-10K models incorporate advanced technology, including automatic calibration and tare functions, which enhance usability and accuracy. The automatic calibration feature ensures that the scales maintain their precision over time, while the tare function allows users to weigh items in containers without needing to account for the container's weight separately.

Durability is another major characteristic of these scales. Built with robust materials, they are designed to withstand the rigors of daily use in busy environments. Additionally, their compact design ensures that they occupy minimal space, making them suitable for various settings, including laboratories, warehouses, and retail outlets.

Convenience is amplified with the inclusion of RS-232 interface options for seamless connectivity to computers or printers, enabling easy data collection and reporting. The power-saving features of both models, including auto-off functionality, contribute to longer battery life, reducing the need for frequent replacements.

In summary, the A&D MC-30K and MC-10K scales are exceptional tools for anyone needing reliable and precise weighing solutions. With their advanced features, user-friendly design, and durable construction, they stand out as top choices for industrial and commercial weighing applications.
