INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780305)

INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780305)

The INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780305) delivers dependable, high-accuracy mass calibration for laboratories that require strict traceability and consistent weighing performance. Therefore, this calibration weight supports demanding applications in regulated, industrial, and research environments. Moreover, Ohaus supplies the weight with an ISO/IEC 17025 accredited calibration certificate, which helps laboratories meet audit, compliance, and quality system requirements with confidence. As a result, users can document calibration accuracy without additional certification steps.

Ohaus manufactures this 10 kg calibration weight in the USA using Troemner Alloy 8. Because of this, the weight offers excellent corrosion resistance, mechanical strength, and long-term dimensional stability. Additionally, the cylindrical one-piece construction enhances mass integrity and reduces the risk of internal structural changes over time. Consequently, the weight maintains stable performance during repeated calibration cycles. With a density of 8.03 g/cm³ at 20°C, it also ensures predictable handling characteristics despite its higher nominal mass.

To protect accuracy during storage and transport, Ohaus includes a dedicated protective case. In addition, this robust case minimizes exposure to dust, moisture, and accidental impact. Furthermore, the reinforced case design improves safety and handling efficiency, especially when working with heavier calibration weights. For this reason, laboratories can move, store, and deploy the weight with greater confidence and control.

The low measurement uncertainty of 3 mg and a tight weight tolerance of 16 mg further strengthen calibration reliability. Therefore, this E2 class calibration weight suits the calibration of precision balances, high-capacity analytical balances, and mass comparators that demand strict control over weighing accuracy.
