INDIVIDUAL WEIGHT CLASS E 2 Ohaus (30390903)

INDIVIDUAL WEIGHT CLASS E 2 Ohaus (30390903)

The INDIVIDUAL WEIGHT CLASS E 2 Ohaus (30390903) delivers dependable, high-capacity mass calibration for laboratories and industrial environments that require strict traceability and stable performance. Therefore, this calibration weight supports critical verification tasks for high-capacity balances and mass comparators. Moreover, Ohaus supplies this model with an ISO/IEC 17025 accredited calibration certificate, which helps organizations meet audit and quality system requirements efficiently. As a result, users can document calibration accuracy without additional certification steps.

Ohaus manufactures this 50 kg calibration weight in the USA using high-grade 316 stainless steel. 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 minimizes the risk of internal structural changes over time. Consequently, the weight maintains consistent performance during repeated calibration cycles. With a density of 7.95 g/cm³ at 20°C, it also provides predictable handling characteristics for large-capacity calibration work.

Unlike lower nominal weights, this 50 kg model does not include a protective case. However, the robust stainless-steel construction protects the weight against wear during controlled laboratory and industrial use. Furthermore, the solid design supports safe handling procedures when technicians follow proper lifting and placement practices. For this reason, the weight remains suitable for fixed calibration locations and routine verification schedules.

A controlled weight tolerance of 80 mg supports reliable calibration at higher capacities. Therefore, this E2 class calibration weight fits applications that require precise control of mass accuracy while working with heavy loads.
