When precision measurement is non-negotiable, choosing the right calibration weights becomes absolutely essential. Masse Präzise’s F Class Analytical Weight Box is engineered for laboratories and industries that demand reliable, repeatable, and standards-compliant performance every single day. Whether you’re working in analytical labs, pharma units, research facilities, or quality control departments, our F2 mass, analytical calibration weights, test weights, and analytical weight box offer unmatched consistency and trust.

Experience Unmatched Accuracy with Masse Präzise F Class Calibration Weights

Precision labs depend on instruments that deliver exact results — and those instruments depend on accurate calibration weights. Masse Präzise F Class Weights are designed for high-precision analytical and laboratory applications, ensuring your balances perform at their peak.

In our demonstration, each weight is carefully placed on a high-precision digital balance to showcase its:

• Absolute accuracy

• Stability over repeated measurements

• Compliance with OIML R111 global standards

This level of precision ensures you get dependable results, whether measuring milligrams or kilograms.

1. Premium Materials for Maximum Stability

The secret to a long-lasting and accurate calibration weight lies in its material.

 Superior Stainless Steel Composition

Masse Präzise uses high-grade stainless steel that offers:

• Excellent corrosion resistance

• Low magnetic permeability

• Dimensional stability

• Smooth, mirror-polished finishing

These properties ensure the weights remain stable under varying environmental conditions — a crucial factor for labs using analytical balances and microbalances.

 Perfect Surface Finish

Each weight undergoes a controlled polishing process, giving it a flawless surface with almost zero imperfections. This prevents dust accumulation and ensures the weight remains reliable for long-term use.

2. Engineering That Meets Strict Tolerance Levels

F Class Weights (F1 / F2) sit at a critical mid-precision stage — ideal for laboratories that need high accuracy but don’t require the cost of ultra-high-precision E Class weights.

Why Tolerance Matters

Tolerance determines how close the actual weight is to its nominal value. Our F2 mass weights follow OIML R111 tolerance limits, ensuring:

• Excellent accuracy

• Repeatability

• Compliance with calibration standards

These weights are ideal for:

• Standard analytical balances

• Precision scales

• Research instruments

• Laboratory routine calibration tasks

Each weight undergoes inspection and verification to ensure it stays comfortably within permissible error ranges defined by OIML R111.

3. Advanced Manufacturing for Consistent Performance

Every F Class calibration weight from Masse Präzise goes through:

- CNC machining for dimensional precision

Eliminates structural variations or imbalances.

- Micro-polishing for surface perfection

Enhances stability and minimizes environmental impact.

- Class-specific shaping and density control

Ensures reliability during repeated testing.

- Traceable calibration certificate

Each set includes complete traceability to national or international standards, making these weights suitable for regulated industries such as pharmaceuticals and chemical labs.

4. Designed for Practical Laboratory Use

A good weight is only as useful as how safely and conveniently it can be handled.

Your analytical weight box includes:

• A durable, shock-resistant case

• Anti-static tweezers

• Gloves for safe handling

• Individual slots to prevent micro-damage

• Soft cushioning to avoid surface scratches

With sizes ranging from 1 mg to 50 kg, Masse Präzise offers one of the most comprehensive calibration weight ranges in the industry.

5. Guaranteed Long-Term Reliability

Every weight in the set is engineered to deliver decades of accurate performance.

From Masse Präzise, you get:

•  High accuracy

•  Superior stainless-steel material

•  Perfect surface finish

•  Traceable calibration

•  Long-term reliability

Whether you are calibrating sensitive analytical balances or conducting precise scientific measurements, our F Class Weights ensure your equipment always performs at its best.
