500g Calibration Weight F1 Class – Precision Standard for Reliable Calibration

When it comes to accurate measurement and calibration, precision is non-negotiable. The 500g calibration weight F1 class from Masseprazise stands as a benchmark for reliability, traceability, and compliance in demanding laboratory and industrial settings. Designed to meet the strict standards of OIML R111-1:2004 and ISO 17025:2017, this high-accuracy weight ensures repeatable results and supports critical calibration tasks with confidence.

Crafted from high-grade Austenitic stainless steel (SS-316), the F1 class weight 500g offers corrosion resistance, dimensional stability, and long-term accuracy. Whether used in a pharmaceutical laboratory, metrology institute, or industrial calibration lab, this weight delivers top-tier performance that meets international tolerances.

Traceability and Accuracy of Our F1 Class Weight 500g

The 500g F1 class calibration weight from Masseprazise is not just a piece of metal—it's a traceable, metrologically verified standard. Each weight is manufactured to meet F1 class tolerances as defined by OIML R 111-1:2004, ensuring high accuracy suitable for calibrating medium-precision balances and as a reference for F2 and lower-class weights.

To maintain the highest level of accuracy, the weight is accompanied by a standard manufacturing certificate and a calibration certificate issued according to ISO 17025:2017. This documentation ensures that the calibration process is traceable to national or international metrology standards—vital for labs following ISO, NABL, or other quality compliance protocols.

Our calibration process guarantees minimal magnetic susceptibility (X < 0.2), reducing any magnetic interference during precision weighing. Additionally, each weight maintains a stable density of 8000 ±30 kg/m³, ensuring consistency across environmental conditions and measurement instruments.

This traceability is critical for:

• Ensuring repeatable and defendable results in regulated environments.
• Supporting internal audits and external certifications.
• Providing documented proof of compliance with national and global standards.

Applications of F1 Class Weight 500g in Laboratories and Industry

The F1 class weight 500g is suitable for a wide range of calibration tasks in laboratories, manufacturing, research, and regulatory environments. Designed to calibrate medium-precision analytical balances, this weight ensures accurate readings across applications where minor deviations can lead to significant product or process discrepancies.

Common Applications:

• Pharmaceutical Laboratories: Used in weighing drug compounds, chemicals, and reagents for clinical testing.
• Calibration Labs: Serves as a reference standard for calibrating lower-class weights (F2, M1, etc.).
• Industrial Weighing Systems: Calibrates bench and tabletop balances used in quality control environments.
• Food & Beverage Testing: Ensures accuracy of ingredient weights in nutritional laboratories and manufacturing units
• Educational Institutions: Utilized in laboratory setups for teaching precision weighing techniques.

Due to its superior finish, high purity, and precision machining, the 500g calibration weight F1 class from Masseprazise is a preferred choice for both routine and critical calibration tasks. It supports the maintenance of a reliable metrological hierarchy in any certified environment.

Material and Design Details of the 500g F1 Class Weight

Masseprazise places a strong emphasis on design engineering and material quality to manufacture calibration weights that meet global expectations. The 500g calibration weight F1 class features a knob-type cylindrical two-piece bar design, allowing for both precision manufacturing and post-manufacturing adjustment when necessary.

Design Features:

• Type:Knob-type, cylindrical shape with smooth edges for safe handling.
• Construction: Two-piece bar design with an internal cavity for adjustment. This allows for recalibration over time without compromising the structural integrity of the weight.
• Surface Finish: Highly polished to minimize dust adhesion and facilitate easy cleaning, maintaining mass integrity over time.
• Marking: Laser-engraved or stamped identification for traceability and classification.
Material Specifications:
• Material: SS-316 Austenitic Stainless Steel, chosen for its non-corrosive properties, high purity, and non-magnetic nature.
• Density: 8000 (± 30) kg/m³ – controlled to ensure consistency in environmental conditions and compatible with precise calibration formulas.
• Magnetic Susceptibility: X < 0.2, meeting OIML Class F1 requirements, ensuring minimal magnetic interference during calibration.

To maintain integrity during handling and transportation, the 500g F1 class calibration weight is securely packed in a hard aluminum case. This packaging protects the weight from moisture, temperature fluctuations, and mechanical damage—ensuring it remains within tolerance for years to come.
