INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780303)

INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780303)

The INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780303) delivers high-accuracy mass calibration for laboratories that require strict traceability and reliable measurement results. Therefore, this calibration weight supports critical applications in regulated and research environments. Moreover, Ohaus supplies the weight with an ISO/IEC 17025 accredited calibration certificate, which simplifies compliance with internal audits and international standards. As a result, laboratories can perform calibration tasks with higher confidence and documented accuracy.

Ohaus manufactures this calibration weight in the USA using Troemner Alloy 8. Because of this, the weight offers excellent mechanical stability, corrosion resistance, and long-term durability. Additionally, the cylindrical one-piece construction improves mass consistency and prevents internal structural shifts that could affect accuracy over time. Consequently, the weight maintains stable performance during repeated calibration procedures. With a density of 8.03 g/cm³ at 20°C, the weight also provides consistent handling characteristics during routine laboratory use.

To preserve measurement integrity, Ohaus includes a dedicated protective case. In addition, this case reduces exposure to dust, moisture, and physical damage during storage and transportation. Furthermore, the compact case dimensions allow technicians to store and handle the weight efficiently within laboratory workspaces. For this reason, the weight remains suitable for both daily use and long-term storage.

The low measurement uncertainty of 0.6 mg and a tight weight tolerance of 3 mg further enhance calibration reliability. Therefore, this E2 class weight supports high-resolution analytical balances, precision balances, and mass comparators that demand strict accuracy control.
