INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780304)

INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780304)

The INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780304) high-precision mass calibration for laboratories that require strict accuracy and long-term stability. Therefore, this calibration weight supports critical weighing applications in research, quality control, and regulated laboratory environments. Moreover, the weight complies fully with OIML Class E2 requirements, ensuring international acceptance and consistent calibration results.

Ohaus manufactures this calibration weight in the USA using Troemner Alloy 8. As a result, the weight delivers excellent corrosion resistance, mechanical strength, and dimensional stability. Additionally, the cylindrical one-piece construction improves mass integrity and minimizes the risk of internal structural changes over time. Consequently, the weight maintains consistent performance during repeated calibration procedures. With a density of 8.03 g/cm³ at 20°C, it also offers stable handling characteristics during daily laboratory use.

To protect measurement accuracy, Ohaus includes a dedicated protective case. In addition, this case shields the weight from dust, moisture, and accidental damage during storage and transport. Furthermore, the robust case design and optimized dimensions make handling safer and more efficient, especially for higher nominal weights such as 5 kg. For this reason, laboratories can store and transport the weight with greater confidence.

The low measurement uncertainty of 1.5 mg and a tight weight tolerance of 8 mg further enhance calibration reliability. Therefore, this E2 class calibration weight is suitable for calibrating analytical balances, precision balances, and mass comparators that demand strict control over weighing accuracy.
