An E1 Class 1 kg Calibration Weight is a primary reference standard used to calibrate precision balances and lower-class reference weights. It conforms to the OIML R 111-1:2004 standard, which specifies the tightest permissible error limits, lowest magnetic susceptibility, and highest-quality construction. At Masseprazise, our E1 Class weights are manufactured with SS-316 non-magnetic stainless steel, ensuring long-term stability, durability, and compliance.
The density of our OIML R111 E1 1 kg weight is 8000 (±30) kg/m³, exactly as required by the OIML standard. This density ensures consistency, accuracy, and predictable performance across calibration applications.
Yes. The E1 Class 1 kg Calibration Mass is highly suitable for pharmaceutical and biotechnology applications where accuracy, traceability, and regulatory compliance are critical. Each weight is supplied with an ISO/IEC 17025:2017 accredited calibration certificate, making it fully compliant with audit and quality assurance requirements.
To maintain accuracy and extend the lifespan:
- Always handle the weight using special gloves or tweezers to avoid contamination.
- Store it in the aluminium hard case provided to protect against dust and scratches.
- Avoid direct contact with magnetic fields or corrosive environments.
- Schedule periodic recalibration (typically annually, or every 6 months in high-regulation labs).
Yes. Masseprazise’s E1 Class 1 kg Calibration Weight is a monobloc (single-piece) knob type design. It contains no adjustment cavity, which eliminates the risk of contamination or material loss and ensures maximum stability over time.
The maximum permissible error (MPE) for a 1 kg E1 Class Calibration Weight as per OIML R 111-1:2004 is ±0.50 mg. This is the tightest tolerance available, making it the most precise 1 kg weight for high-end calibration work.
Yes. Masseprazise offers customization options, including:
- Protective casing choices (wooden, ABS, or aluminium hard case).
- Laser engraving/serial numbering for identification and traceability.
- Calibration certificate options depending on regulatory requirements.
