WEIGHT SETS CLASS F 1 Ohaus (80780412)

WEIGHT SETS CLASS F 1 Ohaus (80780412)

Product Overview

The WEIGHT SETS CLASS F 1 Ohaus (80780412) delivers high-precision calibration across micro to medium mass ranges for analytical and precision balances. Therefore, it enables complete verification of sensitive laboratory weighing instruments. Moreover, compliance with OIML Class F1 ensures dependable mass traceability for critical measurement routines. In addition, this set covers an extended calibration range from 1 mg up to 100 g. As a result, laboratories can perform full multi-range calibration using one organized reference set. Furthermore, optimized construction across different mass values enhances stability. Consequently, drift risk decreases and repeatability improves. Thus, calibration accuracy remains consistent over long-term use.

At the same time, weights of 1 g and above use two-piece construction, while sub-gram weights apply one-piece construction. Because of this, each mass achieves ideal durability and precise handling. Furthermore, Ohaus combines Troemner Alloy 8, stainless steel, and aluminum materials. As a result, density consistency and corrosion resistance remain excellent. Additionally, the protective case keeps all weights clean and secure. Therefore, storage and transport become safe and efficient. Ultimately, this Class F1 set provides dependable precision for demanding laboratory calibration environments.
