Ensure weighing accuracy with certified calibration weights
Calibration weights are precision mass artefacts used to verify, adjust and document scale performance, providing process security and repeatable results in production, quality assurance and laboratories. They come in defined nominal values and accuracy classes such as E1, F1 and M1, so you can match the right weight to the scale’s readability and application to avoid false confidence or unnecessary cost. Correct handling—using gloves or tweezers, storing weights in their case and avoiding contamination—keeps them reliable, while routine checks at multiple points in the weighing range reveal issues caused by vibration or temperature changes.

KERN 315-246 tweezers — stainless steel with bent plastic tips The KERN 315-246 is a 130 mm tweezers designed for safe and precise handling of small test weights in calibration and workshop environments Stainless steel body with premium plastic tips Bent tips for precise grip of small weights 130 mm length for secure handling Suitable for test weights ≤ 5 g (Classes E1–M3) Precise handling for delicate test weights The combination of bent tips and high-quality plastic tips delivers a controlled contact surface that prevents slipping and avoids marking delicate weights. This design makes the tool ideal for manipulation of test masses up to 5 g, including high-accuracy classes E1–M3, where minimal surface contact and repeatability are essential. A curved tip geometry improves visibility at the point of contact, reducing handling time and the risk of measurement deviations in routine calibration tasks. The build supports accurate pick-up and placement, ensuring repeatable handling in laboratory and workshop workflows. Robust construction that limits contamination and wear Manufactured from stainless steel, the tweezers resist corrosion and stand up to frequent cleaning without loss of form. The plastic tips act as a barrier between metal and weight surface, lowering the chance of scratches or contamination that could alter a mass value. With a light overall mass of 0.02 kg, the instrument is easy to manoeuvre, enabling steady operation without introducing torque or pressure that might disturb fragile artefacts. These properties together contribute to more reliable measurement results and a longer service life for both the accessory and the weights it handles. Ergonomic length and geometry to streamline workflow At 130 mm overall length, the tweezers offer a balanced reach for handling weights in pans and small receptacles while keeping the operator’s fingers clear of the weighing area. The bent tip profile provides a natural angle for picking up tiny masses and placing them precisely on a balance pan, reducing contact time and the risk of error. For calibration technicians and metrology professionals, this means fewer handling cycles and improved throughput during verification procedures. The tool’s design therefore supports operational efficiency and helps maintain measurement integrity across repeated tasks.

1kg Wooden Case For Single Calibration Weights Unpadded, For Class F2–M3 - KERN
The supplied product data contains conflicting specifications and cannot be published as a reliable product description. In one part of the information the case is specified as suitable for calibration classes F2 and M1, while elsewhere it is indicated as F2 and M3; this inconsistency affects the declared target use of the wooden weight case. In addition, the listed price values appear contradictory and cannot be reconciled from the data provided, which prevents safe reference to commercial details. Until these discrepancies are clarified by the supplier or the original data source, a production-ready description will not be created to avoid potential misinformation. Please provide corrected and consistent information regarding the calibration class and the pricing details so that an accurate, compliant product text can be produced.

Ensure measurement reliability with certified test weights
Test weights are defined mass artefacts used to verify, adjust and document the performance of scales across production, laboratory and quality assurance environments. They provide the objective reference needed to confirm accuracy, repeatability and process reliability where documented results matter.
How test weights work and where they matter
Test weights serve as traceable references with fixed nominal values — for example 1 g, 100 g, 1 kg or 20 kg — and are manufactured to specific accuracy classes so that permitted deviations are known and comparable. In practice they are used to check a scale’s reading at one or several points within its range, to distinguish between calibration (checking and documenting deviation) and adjustment (setting the scale to read correctly). Typical situations include routine production checks, audit-prepared quality control, laboratory validation and fault-finding when instability, vibration or environmental factors affect readings.
Immediate performance gains for production and quality assurance
- increase measurement confidence by using weights matched to the application and scale resolution
- reduce downtime and troubleshooting time through systematic multi-point checks (lower, mid, upper range)
- protect process validity by choosing the correct accuracy class: E1, E2, F1, F2, M1, M2, M3
- limit handling-related error: use tweezers for small weights and clean gloves for larger items
- extend usable lifetime through disciplined storage in protective cases and regular control or recalibration

FAQ
What exactly are test weights?
Test weights are defined mass artefacts with fixed nominal values that are used to check, adjust or document scale performance within quality assurance and calibration workflows.
Which accuracy classes are available and when should I use them?
Accuracy classes range from E1/E2 for the highest demands, through F1/F2 for precise everyday applications, to M1–M3 for robust industrial or platform scales. Select the class that matches the required measurement uncertainty and the operating environment.
How often should I check my scale with test weights?
Frequency depends on the criticality of the process: critical operations often require daily or per-shift checks, while less critical applications may use weekly or monthly intervals; always check after location changes or suspect readings.
Why must test weights not be touched with bare hands?
Skin oils and moisture alter surface mass and can introduce measurable errors, especially for small nominal values. Use tweezers or clean gloves to maintain traceability and reliability.
What is the practical difference between calibration and adjustment when using test weights?
Calibration documents how far a scale deviates from the nominal value; adjustment actively corrects the scale to bring it back into tolerance. Both processes make use of test weights but serve different quality objectives.
Metav and KERN & Sohn provide the products, documentation and calibration pathways to integrate test weights into routine quality assurance — ensuring your measurements remain verifiable, repeatable and audit-ready.
