INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780306)

INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780306)

The INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780306) delivers robust, high-accuracy mass calibration for laboratories that require strict traceability and dependable performance at higher capacities. Therefore, this calibration weight supports demanding applications in regulated laboratories, industrial quality control, and research facilities. Moreover, the weight complies fully with OIML Class E2 requirements, ensuring international acceptance and consistent calibration results across critical weighing systems.

Ohaus manufactures this 20 kg calibration weight in the USA using high-quality 316 stainless steel. As a result, the weight provides excellent corrosion resistance, mechanical strength, and long-term dimensional stability. Additionally, the cylindrical one-piece construction enhances mass integrity and minimizes the risk of internal structural variation over time. Consequently, the weight maintains stable and repeatable performance during frequent calibration cycles. With a density of 7.95 g/cm³ at 20°C, the weight also offers predictable handling characteristics despite its higher mass.

To protect measurement accuracy, Ohaus includes a dedicated protective case. In addition, this case reduces exposure to dust, moisture, and accidental impact during storage and transportation. Furthermore, the reinforced case design improves safety and handling efficiency when technicians move or position heavier calibration weights. For this reason, laboratories can manage the weight confidently during routine and periodic calibration activities.

The low measurement uncertainty of 6 mg and a controlled weight tolerance of 30 mg further strengthen calibration reliability. Therefore, this E2 class calibration weight suits the calibration and verification of high-capacity precision balances and mass comparators that demand strict control over weighing accuracy.
