KERN 313-05 Weight Set (OIML class E2, 1 mg–500 g)

The KERN 313-05 weight set is a precision calibration kit designed for laboratory and service-scale calibration, covering the range from 1 mg to 500 g in button-form masses.

• OIML class E2 for high-precision calibration
• Range 1 mg–500 g for broad calibration tasks
• Polished stainless steel weights for corrosion resistance
• Supplied in wooden case with separate mg plastic tray

Reliability that protects measurement processes

The set delivers OIML class E2 traceability across a broad span from 1 mg–500 g, providing repeatable reference values for sensitive balances. Class E2 denotes tight tolerance and low uncertainty, which is essential for laboratories and calibration houses that require documented conformity. Using certified masses reduces measurement drift and supports conformity with internal quality procedures and external audits.

Designed for efficient calibration workflows

Button-shaped masses and an organised storage concept enable fast handling during routine checks. The milligram pieces are supplied in a separate plastic tray, simplifying small-mass management and minimising handling contamination. The wooden case keeps the kit accessible and protected, so calibration cycles are shorter and the maintenance routine becomes more predictable — a practical advantage for busy service technicians and in-house calibration teams.

Durable materials for long-term consistency

Manufactured from polished stainless steel, the masses resist corrosion and surface degradation, which helps maintain nominal values over time. Surface finish and material selection are crucial for reducing adsorption of oils and particulates; regular cleaning with appropriate solvents preserves accuracy without aggressive abrasion. Originating from Germany, the set reflects established manufacturing practices for measurement technology, contributing to dependable long-term performance.

Versatile usage across laboratories and workshops

This kit supports a wide range of applications, from balance verification in chemical laboratories to on-site checks in production and quality control. The combination of fine milligram weights and larger gram masses enables single-set coverage for multiple instruments and reduces the need for separate calibration tools. When consistent reference masses are required for routine verification or accreditation activities, this set offers a compact, ready-to-use solution.

FAQ

What does OIML class E2 mean for calibration?
OIML class E2 specifies tight tolerance and low permissible error for reference masses; the KERN 313-05 weight set meets these requirements and is suitable for high-precision calibration tasks and routine verification.

Can the set be used for pharmaceutical and laboratory balances?
Yes, the 1 mg–500 g range and E2 accuracy make the kit appropriate for many laboratory balances used in pharmaceutical and research environments where traceable reference masses are required.

How are the smallest masses protected during transport and storage?
The milligram weights are supplied in a separate plastic tray to prevent movement and contamination; the wooden case provides overall protection and organised storage for the complete set.

Is special maintenance required to preserve accuracy?
Routine handling precautions and gentle cleaning of the polished stainless steel surfaces maintain nominal values. Avoid harsh abrasives; use lint-free gloves and suitable cleaning agents to reduce contamination risks.

Where is the set manufactured?
The masses are produced in Germany, reflecting established manufacturing standards for precision measurement equipment.
