Precision that supports certified results
The OIML class E1 classification signals the highest available accuracy for calibration masses used in laboratories and accredited test houses. With a nominal mass of 2 kg and a stated tolerance of 1 mg, this weight reduces the measurement uncertainty associated with mass verification and adjustment. Laboratories benefit from a clearly defined measurement standard that fits into accreditation scopes; the high-precision specification minimises drift between verifications and supports reliable documentation in calibration logs.
Robust materials and handling for repeatable performance
Manufactured in polished stainless steel, the weight resists corrosion and is easy to clean without affecting the measuring surface, which preserves mass stability over time. The knob form provides safe handling and prevents fingerprints or contamination on the critical measurement surfaces, maintaining the weight’s metrological integrity during transfers and routine use. Durable finish and compact dimensions contribute to long service life and low maintenance within a professional workshop or metrology room.
Practical integration into quality processes
The weight is suitable for use as a reference in balance verification, routine checks and traceability chains within production and quality assurance workflows. Given the E1 accuracy class, storage and transport conditions are important: a protective case is recommended to avoid mechanical damage and contamination that could affect readings. This makes the component practical for fixed laboratory benches and controlled transport between verification points, ensuring consistent calibration results and documented traceability.
