The Mettler AT261 DeltaRange analytical balance is a high-quality laboratory balance designed for highly accurate weighing in research, pharmaceutical, and chemical laboratories. Thanks to DeltaRange technology, the balance can operate with very high resolution in the low weighing range while maintaining a higher maximum capacity.

Due to its robust construction, fast stabilization time, and integrated data interfaces, the AT261 is suitable for applications such as:

analytical chemistry

pharmaceutical quality control

sample preparation

research and development

The glass weighing chamber protects the sample from air currents and vibrations, ensuring accurate measurements remain possible. Technical specifications
