Cotton construction for gentle handling Protects test weights from finger grease Suitable for test weights up to 2 kg Lightweight, reusable pair for workshop use Preserve measurement accuracy with clean handling Handling delicate masses without contamination helps to maintain precision and reduces the need for frequent recalibration. The KERN cotton gloves provide an effective barrier against finger grease and light moisture, keeping surfaces free of oils that can alter measured mass. By preventing direct contact, the gloves contribute to consistent readings and minimise the risk of measurement drift, supporting reliable quality control in routine metrology tasks. Practical protection for everyday workshop routines Lightweight and easy to store, this pair is tailored for straightforward use in production and service environments. The simple design allows quick application while handling small test weights, helping to maintain workflow speed without compromising care. Suitable for masses up to 2 kg, the gloves enable safe manipulation of common calibration weights, combining protection with operational convenience to keep processes efficient and repeatable. Why cotton is the right material for delicate tools Cotton fibres offer a soft, absorbent contact surface that decreases the transfer of oils and residues onto sensitive metal surfaces. The natural fabric reduces abrasion risk compared with harsher materials, providing gentle handling that preserves finish and mass integrity. At an almost negligible net weight, the gloves do not affect the handling ergonomics of small weights but do increase confidence in routine handling and storage practices.

Take advantage of a robust combination of lightweight aluminium protection, a padded interior and certified suitability for calibration classes F1–M3 to keep block weights safe in transit and storage. Order the case directly via Metav Werkzeuge or consult the Metav team for specification support. KERN 346-080-600 Aluminium-protected case for block weights, padded The Aluminium-protected case 346-080-600 is a padded transport and storage solution designed for block calibration weights used in laboratory and industrial environments. Aluminium protection housing Padded interior for secure storage Designed for block weights up to 20 kg Suitable for weight classes F1–M3 Robust protection that preserves calibration integrity This lightweight aluminium housing combines structural rigidity with reduced mass, creating a reliable shell for sensitive calibration artefacts. The internal padding secures each block against shocks and vibrations, lowering the risk of dents or surface damage that could alter mass distribution and affect accuracy. For metrology departments and service technicians, a well-protected weight reduces the frequency of re-calibration and associated downtime. The transport case is engineered to match the handling patterns typical for laboratories and mobile calibration services, translating to measurable savings in time and maintenance costs. Designed for calibration workflows and secure handling The case is tailored for block weights, offering precise cut-outs and cushioned support to prevent movement during handling and transit. By ensuring that each weight remains immobile, the case helps maintain the declared tolerance class throughout storage and transport. Compatibility with F1–M3 tolerance classes indicates suitability for a broad range of calibration tasks, from precision laboratories to routine verification in production environments. The combination of a corrosion-resistant outer shell and internal padding also simplifies logistic processes: weights can be moved between sites without additional packaging and with preserved traceability. Practical meaning of classes and how they benefit operations Tolerance classes such as F1 and M3 specify permissible deviation ranges and are widely used in traceable mass measurement. Choosing a dedicated storage solution for weights intended for these classes safeguards the nominal value against mechanical or environmental damage that could invalidate the calibration status. For teams responsible for quality assurance, using a purpose-built protective case reduces the risk of non-conformances during audits and supports consistent measurement results. The case also supports efficient organisation in the workshop or lab, keeping block weights accessible, identifiable and ready for use.
