OIML R111 F1 Class Calibration Weights (1 mg–1 kg) | Masse Präzise

All F1 class calibration weights supplied by Masse Präzise conform to the OIML R111 international recommendation, which defines accuracy classes, permissible errors, material specifications, and surface finish requirements.

Key Features of OIML R111 F1 Weights:

• Manufactured as per OIML R111 standards
• Suitable for calibrating Class I and Class II balances
• Low magnetic susceptibility
• High resistance to wear and environmental influence/li>
• Consistent density and superior surface finish

These characteristics make F1 calibration weights ideal for laboratories that require higher accuracy than F2 class but do not need ultra-sensitive E-class standards.

F1 Class Calibration Weight Box 1 mg to 1 kg – Precision Weights

For safe handling, organization, and long-term protection, Masse Präzise offers F1 class calibration weight boxes covering the full range from 1 mg to 1 kg.

Advantages of an F1 Calibration Weight Box:

• Complete weight set stored in a single protective case
• Minimizes risk of contamination, scratches, or mass deviation
• Easy identification and secure placement of each weight
• Ideal for routine laboratory and calibration use

Each calibration weight box is designed to meet professional laboratory requirements, ensuring that weights retain their precision throughout repeated usage cycles.

High-Precision F1 Class Weights Set (1 mg to 1 kg) for Laboratories

Laboratories demand reliability, repeatability, and traceable accuracy. F1 class analytical weights are commonly used in:

• Analytical and research laboratories
• Pharmaceutical and chemical industries
• Academic and institutional laboratories
• Compliance testing in legal metrology.

The weight is delivered with a standard manufacturing certificate as well as a calibration certificate, both traceable to OIML and ISO standards. The calibration certificate is issued in accordance with OIML R111-1:2004 and ISO 17025:2017, ensuring international traceability and reliability in testing laboratories.

F1 Analytical Weights 1 mg–1 kg | OIML R111 Standards

The 1 mg to 1 kg range covers micro, analytical, and mid-capacity calibration needs. This wide spectrum allows laboratories to calibrate balances with different capacities and readability levels using a single standardized set.

Typical Applications:

• Calibration of analytical balances
• Routine verification of laboratory weighing instruments
• Reference standards for internal calibration
• Compliance with ISO, NABL, and GMP requirements

By adhering to OIML R111 F1 standards, Masse Präzise ensures that each weight meets strict tolerance limits, supporting high-confidence measurement results.

F1 Class Weights Set 1 mg to 1 kg – Laboratory Test Weights

As laboratory test weights, F1 class weights play a critical role in maintaining the integrity of measurement systems. Their superior accuracy makes them suitable for environments where even small deviations can impact test results, formulations, or compliance outcomes.

Why Choose F1 Class Test Weights?

• Higher accuracy than F2 class weights
• Stable mass characteristics over long periods
• Suitable for controlled laboratory conditions
