WEIGHT SETS CLASS F 1 Ohaus (80780409)

WEIGHT SETS CLASS F 1 Ohaus (80780409)

Product Overview

The WEIGHT SETS CLASS F 1 Ohaus (80780409) delivers high-precision micro and small-mass calibration for analytical and precision balances. Therefore, it supports full verification of sensitive weighing instruments in laboratory environments. Moreover, compliance with OIML Class F1 ensures dependable mass traceability for quality-critical measurement routines. In addition, this set covers a complete range from 1 mg up to 5 g. As a result, laboratories can perform 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 performance remains consistent during long-term use.

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