HR-202i Analytical Balance with Internal Calibration
The HR-202i is a high-precision analytical balance offering exceptional performance at an affordable price. This model features dual weighing ranges with 0.01mg semi-micro resolution, internal calibration capability, and comprehensive data management features suitable for regulated laboratory environments.
Dual Range Weighing Performance
The HR-202i provides two distinct weighing ranges to accommodate different precision requirements: a high-capacity range of 220g with 0.0001g resolution, and an ultra-precise range of 51g with 0.00001g (0.01mg) resolution. This dual-range capability allows users to maximize accuracy when weighing smaller samples while maintaining versatility for larger items.
