KERN 366-88 Block calibration weight (OIML M3, 20 kg)
A KERN 366-88 block calibration weight designed for routine verification and adjustment of industrial scales and balances in workshops and quality departments.
- OIML class M3 certified accuracy
- Nominal mass 20 kg
- Painted cast iron block design
- Tolerance ±10 g for reliable calibration
Consistent reference mass for accurate scale adjustments
The OIML M3 rating and the tolerance ±10 g provide a clear, traceable benchmark for frequent load checks and routine recalibration. As a mass standard suited to industrial environments, this block ensures measurement repeatability, reducing uncertainty in everyday weighing tasks. The nominal 20 kg mass is widely compatible with floor scales and bench balances, enabling efficient calibration cycles and predictable measurement outcomes.
Durable block construction that withstands workshop use
Manufactured from painted cast iron, the solid block format offers mechanical stability and resistance to knocks common in production areas. The compact rectangular shape simplifies handling and secure placement on weighing platforms, while the protective coating reduces corrosion risk and surface wear. These material and design choices translate into lower maintenance needs and longer service intervals for reference weights used in busy workshops.
Clear certification and practical application in quality processes
Certification to OIML M3 clarifies the permissible error band and supports documentation for internal quality systems. The tolerance ±10 g corresponds to measurable limits that can be directly applied to acceptance criteria during scale verification. The mass standard is therefore suitable for routine verification tasks, quality control checks and as a working reference in calibration routines where legal-for-trade high-precision weights are not required.

Take advantage of gentle, cotton handling and reliable contamination protection to extend the service life of precision weights; order directly from Metav Werkzeuge or contact our consultants for tailored advice. Gloves KERN 317-280 — Cotton gloves for protecting test weights up to 2 kg The Gloves KERN 317-280 are designed to protect test weights and precision masses from finger grease and moisture during everyday handling in workshops and calibration labs. 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.
