50 g Calibration Weight Button Shape Fine-Turned Stainless Steel, OIML M1 Tolerance 3 mg - KERN

Product information "50 g Calibration Weight Button Shape Fine-Turned Stainless Steel, OIML M1 Tolerance 3 mg - KERN"

Combine the OIML M1 accuracy with a precision-turned stainless steel body and compact knob shape for dependable, repeatable calibrations; order the calibration weight directly via Metav Werkzeuge or consult our specialists if additional data or DAkkS calibration is required.

KERN 347-06 calibration weight (OIML class M1, 50 g)

The KERN 347-06 is a precision calibration weight in a knob shape, designed for scale verification in laboratories and industrial workshops.

  • OIML class M1 accuracy, tolerance 3 mg
  • Precision-turned stainless steel body
  • Compact knob shape for safe handling
  • Suitable for scale verification and calibration

Consistent traceability for reliable results

As an OIML M1 single weight with a nominal value of 50 g and a stated tolerance of 3 mg, this calibration unit supports reduced measurement uncertainty in verification tasks. The classification ensures compatibility with many laboratory and industrial metrology procedures; when used within a documented calibration scheme, the result is enhanced traceability and comparable readings across different instruments. The combination of class and tolerance directly benefits quality control processes by providing objective, reproducible reference points for balances and scales.

Durable construction and handling that reduces errors

Manufactured from precision-turned stainless steel, the weight resists corrosion and surface wear that can alter mass over time. The knob shape improves manual handling, minimising contact with the measurement surface and thereby cutting the risk of transfer of oils or debris that affect accuracy. With compact cylinder dimensions of approximately 18 × 29.5 mm, the design balances ease of use with stability on weighing pans, helping technicians perform repeatable checks with fewer handling-related deviations.

Practical guidance on calibration and compliance

The product is well suited to routine verification and calibration tasks; however, note that EC type approval for calibration weights will not be available after 30 November 2025. For traceable results that meet most industrial and laboratory requirements, a DAkkS calibration is recommended as an equivalent solution for evidence of accuracy. DAkkS calibration provides an accredited certificate and establishes a documented chain of measurement traceability that integrates readily into quality management systems and audit trails.

A compact reference weight for busy workshops and labs

This single weight serves as a practical reference for technicians and calibration engineers who require a small, robust standard for frequent checks. The durable material and precise machining lower the need for immediate replacement, while the clear technical class and tolerance support informed decisions within maintenance schedules. As part of a calibrated set or as an individual reference, it contributes to consistent process control and confidence in day-to-day weighing results.
